I'm so glad I found this place! I hadn't had a primary care doctor in over 10 years, and even before that, I only had one for about three years. I've always had trust issues with traditional healthcare. Too often, it feels like the focus is on following protocols and prescribing medications rather than understanding the root cause of health problems. I see more and more people struggling with their health despite regularly seeing doctors. Many talk about preventive care, but I've rarely seen it truly put into practice. I've always been passionate about keeping up with the latest medical research, scientific discoveries, and advancements in functional and preventive medicine. I wanted a doctor who was open-minded, looked beyond conventional approaches, and focused on optimizing health rather than simply treating illness. Dr. Matisse offers exactly the kind of care I've been searching for, and at a surprisingly affordable price. Similar practices can cost thousands of dollars a month, making this level of personalized care inaccessible to many people. My first meeting with Dr. Marissa was music to my ears. She spoke about modern approaches to healthcare, the importance of understanding the body as a whole, and using deeper testing and research to identify potential issues before they become serious problems. For the first time, I felt like I was having a conversation with someone who shared my curiosity about health and understood the kind of care I had been looking for all these years. What impressed me most was her willingness to listen, think beyond the standard approach, and have an actual conversation rather than simply rush through an appointment. It's refreshing to find a practice that embraces modern medicine, prevention, and long-term health without charging an outrageous premium. I'm still early in my journey with them, but my first impression has been excellent. I'm genuinely excited to finally have a primary care doctor again, and even more excited that it's someone whose approach to healthcare aligns with what I've believed in for years. I hope more medical practices eventually move in this direction. Healthcare shouldn't just be about managing disease. It should be about understanding our bodies, preventing problems, and helping people live healthier, longer lives. read more

I had been in the market for medical insurance through Covered CA but the cheapest one I could find, that also allowed me to go to the doctors I had been going to for years, was a bit expensive. I decided to look into other options and did a search for places I could pay out of pocket. When I lived in Mexico, I had been using the services at a local hospital, paying a monthly membership fee for their services so imagine my surprise when I found out that the exact same system existed here. That was when I found Dr. Marisse so I booked an appointment. I found her originally on Zocdoc and the nearest appointment was in a month and a half. Within a day of making the appointment, I was called by the office to Nurse Shawna who wanted to make sure that I knew that all appointments needed a preliminary chat with the Doc, after which I could book my appointment. thanked me for letting her know that the next available appointment was that far away. It turned out there was a mix-up and that she did have more immediate appointments available. There is plenty of parking, as it is in shared parking lot with other businesses. However, there are two buildings with the same building number but with different locale numbers. Upper Echelon is in the building nearest to the AAA and the Farmer Boys. At the appointment, everything was clearly explained and we went over a sort of plan of attack, with regards to my concerns and what I needed to do. I appreciated paying less per month for the membership, which includes as many appointments as you want. The lab work and the tests are at wholesale prices so even with the membership fee and registration, all of this was cheaper than the plan I was going to get with insurance. What I appreciated was the quickness of getting an appointment. I have always hated waiting a few weeks, as a new patient, before actually being seen but I was able to book this within a week of the appointment. It was a week because their availability interfered with my work hours. Otherwise, I would have been seen earlier. All in all, it is pretty convenient and a wallet-friendly option. After that first appointment and the lab results came in, Dr. Marisse wrote a VERY long email detailing every point of concern. Which I appreciated because I went for answers and I was getting them. If you need a straightforward person to tell you what you need to be doing and not someone who has to be on your ass every step of the way, this is the ideal option. I would say the ONLY con is that they do not have appointments during the weekends. And since I work during the week, I have to take time off to go to an appointment. read more

I always have excellent experiences at Upper Echelon Medical Office in Fullerton. From the moment I walked in, everyone was welcoming, professional, and made me feel comfortable. A special thank you to Shawna and Karla--they went above and beyond to provide outstanding care. They were incredibly kind, attentive, and took the time to answer all of my questions without making me feel rushed. Their professionalism, compassion, and positive attitudes truly made a difference and turned what could have been a stressful visit into a great experience. It's rare to find a medical office where you feel genuinely cared for, and Shawna and Karla exceeded my expectations. I highly recommend Upper Echelon Medical Office to anyone looking for quality care and exceptional customer service. Thank you both for making my visit such a positive one! Dr. Marisse is truly one of the best doctors I've ever had. She explains everything clearly, never makes you feel rushed, and always makes you feel like your health and well-being are her top priority. Her professionalism and caring attitude give me complete confidence in the care I receive. I highly recommend Dr. Marisse to anyone looking for an exceptional physician. read more

My first experience with a concierge doctor and I would say it was just ok. My first appointment I was prescribed an inhaler and then a few appointments later they asked if I had an inhaler- I thought that was strange since they prescribed me one...shouldn't that be in my chart? I had an xray done for my right collarbone/shoulder area. I was emailed about how my left looked like nothing was wrong and I had to remind them it was my RIGHT I was concerned about.. Doctors are very nice, and they are able to see you quickly/respond quickly. Just not for me. read more

I've been going to Dr. Marisse for almost two years and it has been one of my best things I could have done for my health. Dr. Marisse is knowledgeable, friendly and having a doctor available whenever you need is priceless. Her staff (Karla and Shawna) are amazing as well. Both are very friendly and efficient whether it's scheduling appointments or answering questions I may have, they are so efficient at what they do. I highly recommend Upper Echelon Medical for all your primary health needs! read more

I just started my membership with Dr. Marisse and her lovely staff, including Shawna and Kayla. They are all so wonderful. I love how quick they are. My first appointment they were all so kind and sensitive. Dr. Marisse listened to my ranting patiently, lol. I also joke a lot, and they laugh at my jokes - they are very down to earth, yet educated and professional. They made me feel welcome from the start. Dr. Marisse is very educated. Our first appointment, and she provided me more information than any doctor I had before her. I do appreciate and like how she is very thorough, especially wanting to get to the root cause of the issue and explaining alternative ways we can heal our parasympathetic nervous system. I had never heard of that before, but I did my research afterwards, and I knew she was more than just a regular doctor. The next day, they scheduled blood work, and again, they were very quick. I was in and out without any waiting. It's not something I'm used to. I do love that they have upfront pricing, unlike insurance companies that can give you surprise bills after your visit. I look forward to working with them on my health journey. I am excited to see how I can heal myself, especially with the health concerns that I've been struggling with for many years. Dr. Marisse and her team are very special! I'm very inspired, motivated, and determined to get my health on track and to take accountability for myself with their medical expertise. read more

The visit was amazing! Dr. Marisse is a doctor I only wished to find all these years! I felt heard and I felt like she genuinely cares to help me feel better. She created a personalized plan for me that addressed my specific conditions and recommended diets to improve my general health. The office is conveniently located and is clean and inviting. Looking forward to my next visit. read more

Medical doctors are inundated with an overload of patients, so of course one's needed medical care falls by the wayside. I'm 74 years and have changed doctors numerous times because I am not only a holistic health care practitioner myself but also avoid medications unnecessary for me. I agree that in dire situations medications are needed for a temporary fix. Dr. Marisse is the first doctor who I so appreciate and the time spent with me on my first evaluation visit I have never experienced with any doctor. 1 hour wow! She truly is an asset to her professional she truly cares about her patients too, I have found my forever primary care doctor who truly understands what my needs and desires are, she get an A++ in my opinion. Her office staff is also exceptional too! Very professional and helpful! I would highly advise anyone looking for a doctor that has their best interest to go for a meet and greet with Dr. Marisse Herrera, you won't be disappointed! read more

I can't say enough good things about Dr. Marisse and Upper Echelon Medical Center. After years of regular bloodwork with other doctors, she was the first to catch my vitamin D deficiency -- something no one else had ever noticed. That discovery alone has made a huge difference in how I feel. Her accessibility and commitment to her patients are incredible. The membership model makes everything so easy -- I can message her directly, get quick responses, and even schedule same-day appointments when needed. I highly recommend her and her team for anyone looking for attentive, thorough care. read more

Dr. Marisse was a great physicia! I loved her approach thru holistic healing. very great bedside manner and calming aura! highly recommend if you're looking for alternative healing. read more

Highly recommend! Dr.Marisse takes the time to listen and address my health care needs. She responds to emails in a very timely manner. I had an emergency prescription request while she was out of office and I got the medicine I needed the same morning. Karla in the front office responds quickly to patient requests as well. I'm so grateful for Upper Echelon Medical. My blood pressure is even lower when I visit their office! read more

Highly recommend if you're looking for reliable and professional medical care. read more

This is the best Doctor's visit I've ever had, Dr Marisse is not a Doctor who talks down to patients and uses confusing medical jargon a patient doesn't understand. She is caring, listens to the patient and stresses the fact that a Doctor-patient relationship is a partnership. She's wonderful. The nurse and office staff are on point, communicate clearly and timely. I highly recommend Dr Marisse and have already shared her info with some of my friends who are sick and tired of medical system as we know it (basically serves the interest of corporations and insurance companies. read more

I'm so glad we found Upper Echelon. The care I've received far surpassed the platinum PPO I had that didn't cover the critical care I needed. I highly recommend Upper Echelon. read more

Wow! I could not be happier with Upper Echelon Medical. The entire staff is so compassionate and caring. Dr's. Marisse and Kevin take the time to truly listen and understand what you are experiencing and take a 360 degree approach to your care. They take the time to explain everything.

Upper Echelon is amazing! I've been telling all of my family about it so far! Dr.Marisse was so kind and explained everything in a way which is perfect for me to understand. I was happy with how long and detailed our first meeting was. It made me feel secure in the fact that I will be receiving both quality care and support. The fact that an all women team was present also made me feel strongly about my experience. Everyone was truly amazing and I can't wait to go back! read more

Tired of the traditional take a number doctors visits, I looked for a better way to better health. I found it here and I'm looking forward to getting healthier with better support. Highly recommend. read more

Dr. Marisse at Upper Echelon Medical is amazing. She really takes a holistic approach and makes you feel cared for as a whole person, not just a symptom. I love how quickly she replies and makes herself available when you need her. The office is welcoming and the staff is great too. I am so glad I found her and highly recommend her care. read more

Dr Marrise is so nice and helpful. I would definitely go back to her. She did not rush me through describing my experiences like other doctors and gave me great holistic and medicinal suggestions to help me manage my health. I would recommend her services to anyone. I think as a woman it's important to have Doctors who are in tune with woman's needs and patient care and she definitely demonstrates that. I also was pleased that she offered medicine at a affordable rate in this day and age and had bloodwork immediately available at a low rate. She is patient and kind and does not rush her patients through their questions. 5/5 Stars for Dr Marisse! read more

Wow! This is how healthcare should be. I feel like not telling others would be greedy. The amazing care of Dr. Marisse is worth it many times over. She doesn't rush you out. Everything I read about her and her practice is true. I drive 20 miles to see her and I would drive even further. Seriously, it's worth it. I like the DPC model instead of the insurance craziness. Not only that, but it makes way more sense to continually be a client. Upper Echelon's model isn't something I was familiar with, but seriously as many visits as you need, plus services from others at cost/wholesale...I mean, come on...this is an industry game changer. I could go on and on, but I'll spare you. The care and service is superb and efficient. Booking an appointment is easy and convenient. Oh and on top of all that, I love their office. It's clean and modern and has a really nice vibe. So glad I found them! read more

Dr Marisse is great! She takes the time to get to know you. Ask all the questions that others don't. She listens to whatever questions, comments, or concerns you might have. I've been recommending her to all my friends and family. 10/10 read more

My kid wanted their ears pierced and we didnt want to do it at the mall. Therefore we looked up a few places like tattoo parlors but ended up coming here given reasonable cost. Booking is super easy and they do text message follow ups! We had a day where we were unsure of what was happening and texted and got a response in 10 minutes. Way better than normal health care systems! The doctor was also really nice and understanding, patiently waiting for me to quiet my kid while they cried. Highly recommend the office especially for someone that want a more specialized care for piercings kids ears. It came with the diamond plastic earrings. They are nice and stay really well! read more

Upper Echelon Medical - Ear piercing comes with a plastic diamond earring - Osteopathic Physicians Near Me - Fullerton, California

Came here to get my 4 months old baby ear piercing. Dr Kevin explains everything really well and there are 3 other staff watching us in the room. He used a pen to mark the ears to make sure they are even on both sides. He did the piercing on both sides of my daughter ears at the same time using the gun piercing. the worst part is he MiSSED the spot on the right ear. So he unplugged the earring and pierced the right ear again. My baby screaming crying as it hurts. she got pierced three times in the short amount of time. It's very unprofessional as an experience doctor to make that kind of mistake. He did apologize and followed up on the next day by the phone call but I really don't recommend this place for ear piercing especially for infants or toddler. read more

This is the best doctor that I've ever came across and I am so thankful that I found her. This office is very different than any other office I've been to. Once you arrive for your appointment, the focus is on you and only you, no waiting in line. Marisse Herrera listens to everything you have to say and she cares so much about her patients and gets you the help you need. I am very comfortable here and I highly recommend her! read more

Absolutely amazing service and care. I would highly recommend this medical office. Thank you

My first visit at Upper Echelon Medical was a pretty good experience. Doctor Marisse took her time during my visit, thoroughly discussed the plan, and provided follow through. I very much appreciate this type of medical service. The office personnel was friendly and welcoming. My family and I are very fortunate to have found a group of doctors that truly care for their patients. read more

You know how you constantly switch hair salons in search of the perfect hair stylist who understands exactly what you want and can deliver? The one who you show a picture to and it turns out exactly like it and and how you want it? Well, that's what I found with Dr. Marisse, but for something much more important, my health! It's easy to get comfortable in certain circumstances, even if it's not the best for you, because it's familiar and you know what to expect. That's how I was with my health care. I knew it would take weeks, even months if I needed a specialist, to make an appointment. I knew when I got to my appointment, I'd be packed in a waiting room with people who had the same appointment time or even earlier ones than me. I knew when I met with my doctor, I would spend 8 minutes getting reacquainted with her while she read through my charts. Then the final 2 minutes would be spent on the actual appointment. Often, it wasn't even my doctor, but whatever PA was available that day. I didn't know there was any other option, until I found Upper Echelon Medical and Dr. Marisse. I actually heard her name from my mother-in-law a few years ago. She's with Kaiser Permanente and mentioned her former doctor recommended plantbased whole foods as an option. Once I heard that, I knew Dr. Marisse was speaking my language. But for those of you who aren't into all that, she's definitely trained and well-versed in traditional medicine too. The only thing that kept me from contacting her sooner was her "membership model." I had no clue what that was or how it worked. After years of dealing with conventional doctors and going through insurance, that's what I was used to, what I was familiar with. When I met with yet another doctor last year -- who I don't think ever made eye-contact, then scheduled a bunch of tests without explaining what they were or why I needed them, then later called to tell me my blood tests were "normal" but my cholesterol was "slightly elevated" and if I wanted to discuss possible medications for that -- I figured I'd meet with Dr. Marisse and figure out the membership model later. I'm so glad I did. Dr. Marisse took her time to really get to know me, listened to all my babble, and answered every one of my questions. She didn't rush me out to get to her next patient. She even followed up with an email summarizing my visit and next steps. She scheduled blood tests, explaining why each was necessary. Going through her instead of my insurance (although that was also an option), actually saved me a lot of money. I apologize for the length of this review, but I have to mention, Dr. Marisse went through all my bloodwork results with me. She explained what everything meant and what could be done to improve certain numbers. For one number, I was in the "normal" range. Dr. Marisse said I passed, but asked if I just wanted to pass or if I wanted to get an A+. My husband chuckled and agreed, Dr. Marisse and I are on the same page. So, don't worry about this new-fangled membership model. It's definitely worth it to work with a doctor who actually cares. Plus, it's not as bizarre as you may think and may even save you some money. read more

This is a long overdue review, but I have to express my gratitude for Upper Echelon Medical. Dr. Marisse is truly amazing! Visiting the doctor is never fun, and I used to hate going, but my experience here has been different. I stumbled upon Upper Echelon Medical while searching for a primary physician for my husband on Yelp (definitely not for myself, haha). After calling several clinics and finding everyone fully booked, I called Upper Echelon Medical, and they scheduled my husband for a same-day appointment. Some might assume that because they had availability, they might not be good, but the reason they have time for their patients is because they are a direct primary care facility, which means no insurance headaches. On the same day they scheduled my husband, I signed up for their services too, and it was one of the best decisions I've made. During my first visit, I was nervous because I found out I had COVID, but aside from that, they've been incredibly helpful with everything. They are very hands-on and proactive. They took care of obtaining records for my pap smear, handling the entire process of requesting records from another facility. They did the same for my husband, contacting his previous doctor to retrieve his records. It's rare to find a place that genuinely cares about its patients, takes the time to get to know your lifestyle, and doesn't rush you in and out. I wholeheartedly recommend Upper Echelon Medical. They are truly a blessing, providing an amazing level of care and service. read more

Dr. Herrera did an office visit for a family member of mine who had extreme complex condition and on the verge of passing away. Dr. Herrera spent more than 2 hours with us going over options. Not only did she extend utmost professionalism as a provider but her countless follow up to give advice and also to see how our family member is doing genuinely warms the heart. In a age where we are just a number to the medical system. It's a thrill to see real patient care still exist, and is well very alive with Dr. Herrera and her team. Thank you again Dr. Herrera for going above and beyond the call of duty for us. I wish I live in the area because Upper Echelon is really a no brainer for anyone who can afford the low membership fee. read more

I'm truly grateful I discovered Upper Echelon Medical and Dr. Marisse this past month, as someone who had not visited their primary care provider in years or had any type of check up recently, it was nice to easily become a member of UEM and make an appointment with virtually no wait time. During my first visit, Dr. Marisse made me feel comfortable and heard, she sat with me for about 45 minutes and never rushed me out even when I had further questions, followed by a comprehensive email with a step by step guide to improve any issues I was having and how to maintain healthy habits long term. I also got my blood work done thanks to her amazing assistant Karla, who is always super responsive and accommodating and received my results back within one day. As someone who is trying to fully lock in on their health, it has been reassuring to know that they're available over text and email during business hours and make you feel cared for as a patient, I'm glad I became a member! read more

Best doctors office I have ever been to. The doctors respond quickly, spend time with me, and always makes me feel heard and cared for. I'm thankful I found this place. The medicine is cheaper, and I have easier access to care. Worth every penny! The psychoeducation from the doctors allow me to understand my body better, and learn as I go. The atmosphere is clean, sterile, and warming. The medical staff are friendly, and welcoming. read more

Looking for a doctor that's genuine and passionate about his or her practice is hard to find. Often times the structure of our health care system does not promote actual care and proper examination. Like a month to month membership, you can hone in on your health and game plan what needs to be done to improve your well-being. Health is wealth right? Prior experiences with other doctors, I've felt most don't really listen. If you feel like your current doctor is just booking you for a check, then give Dr. Marisse and the staff of this practice an opportunity. You're treated with respect, great bedside manner, and given actual time to focus on what you need to do to address any potential and or current health issues. Though only my first visit, I feel I already got to build a real patient-doctor relationship and the staff here are kind and professional as well. Any questions and concerns aren't just dismissed with a quick prescription, and you have access to communicating directly with your doctor. Don't sleep and tap in with this team of real people that care!! read more

I rarely leave yelp reviews, but felt inclined to leave one as I had a wonderful experience with Dr. Marisse. As a pharmacist myself who has worked in multiple hospitals and clinics, I can say confidently that Dr. Marisse is a excellent physician and truly cares about her patients. She was incredibly thorough, transparent, sharp and caring. You could tell she is very passionate about medicine and her patients. I had a few extra concerns at the end of our appointment and she made me feel so comfortable and took extra time examining and answering my questions. Marissa is also so friendly, professional and communicative when scheduling appointments and also drawing blood! I HIGHLY recommend Upper Echelon Medical! read more

I want to thank Dr. Marisse and her team for helping me address my mental health. Before I started going to Upper Echelon I was getting my anxiety and depression medication for triple the cost of what I am getting with them. She was able to explain more of what I was going through to help me feel better about myself. She is much more understanding and easier to talk to. If I need a refill I am able to text my doctor for a refill and I can pick it up within two days if not the next day. I was also experiencing some bloating and she was able to take her time to massage my stomach and explain why I may be inflamed. She gave the best advice and future planning to keep me healthy. I appreciate Upper Echelon! read more

Dr. Marisse is so thoughtful every time I speak with her. She takes the time to hear you out and provides advice and follow up care so you know how to prevent it in the future. I was experiencing migraines one day and I was able to do a quick video call same day to make sure it wasn't anything more serious. I was able to make an appointment for the next day and got looked at and she explained what was the root cause of my migraines. The type of natural medicine she is practicing is helping me in the long term to deal with all my health concerns. I truly enjoy the care Upper Echelon provides for me. read more

What a refreshing experience. Dr. Merisse Herrera is the best! So caring and thorough. Phenomenal, thoughtful reporting following the initial exam, crafted into a detailed e-mail which provides links to specific issues of concern. Ongoing and personal assistance with our health issues.

This is a great set up! This made alot of sense for me since my INS still needed me to pay a copay for general doctor visits, which was around the same amount I would pay monthly with Echelon. The doctor is super responsive and you can always get ahold of someone. Multiple ways to contact them. In house meds that are cheaper than your local pharmacy. I've been very happy with the management of my condition and a proper diagnosis which was confirm my multiple specialist. read more

Dr. Marisse and staff were a major part of my road to a better health. When I first signed up and took my first blood test, I was informed I had various health concerns I needed to be mindful of. Fortunately nothing was serious but Dr. Marisse stressed the importance of lifestyle changes I would need to consider to improve my overall well-being. Since the very first day I signed up she followed up with me regularly to ensure I was on track. She was also readily available anytime I needed to ask her questions. To the medical staff: Thank you for all that you do. read more

Dr Marisse and her team were amazing! I have not been going to doctors since Covid started in 2020 other than to see my specialist whom I HAVE to see to get my medicine. I was looking fora family medical doctor and found this office which treats their patients homeopathically and/or with medicine...integrative(?). Dr.Marisse took her time asking me lots of questions and allowing me time to answer without rushing. So unlike most doctor's offices today! I could not be happier! I look forward to my journey toward total health and healing with an office that is unlike any other I have seen! read more
