We were referred to Dr. Dezfoli by our GP. My sister had severe anemia and we needed to find out why. Dr. Dezfoli performed an endoscopy and found that she had an ulceration in her esophagus and severe damage due to acid reflux. He also noticed two lumps in the lining of the stomach. She needed a specialized endoscopy with ultrasound. He was able to refer us to a top notch gastroenterologist at Cedar Sinai and with his connections to the hospital we were able to get an appointment within 2 weeks. With the help of Dr. Dezfoli, and his diligence we are working on getting her back to health. He and his staff are wonderful to work with. read more

If you're trying to book a colonoscopy this is the place to go, if they accept your insurance of course. And if they don't accept your insurance get different insurance and go here. From start to finish I was treated with professionalism, speed and courtesy. Kind staff and responsive staff all the way through. Truly night and day above other providers I had contacted who never even returned my call from their robot voicemails. Here it was personal and caring from the consultation to the procedure and the follow ups. read more

I went in for a consultation in preparation for a colonoscopy, but it turned out to be nothing more than a giant upsell opportunity. We'll do genetic testing! We'll do a mail-in stool sample! We'll do a liver scan! OK, I said, as long as these tests are covered by insurance. Turns out they told my insurance company that I'm an alcoholic to try to induce them to cover the liver scan. WOW! I am just speechless. If this doctor cannot survive through legitimate procedures, there is something terribly, terribly wrong here. Run screaming, like I did. read more

Dr. Dexfoil is a great and caring Doctor. I took my friend with me, and she said she would go to him in a heartbeat, from what he had done for me and how professional he is. And he even has jokes to make you feel at ease. I go back in a few months for a follow-up. He is so thorough in making sure, We can take care of this issue I have. I can't thank him enough, and his staff. read more

Awful place and service. They lie. "We called you". No they did not. Cancelled appointments due to "family issues", and promised to fit me in afterwards, and after labs, they never did. No call back with lab results. Need a preauthorization for a prescription, that's an additional $30; you're a healthcare provider, it's part of your job to obtain preauthorizations. Call from the office? Well, that's apparently considered an office visit, and you'll be billed for a co-pay. Do they tell you this? NOPE! Just a bill from insurance. Long are the days of Dr.'s actually wanting to actually help patients. No, this place is a sham. They want you to use their "Prescription Center". Be prepared to wait until close to midnight for delivery, if it even gets delivered at all at the promised date. Kick backs? Most likely. STAY AWAY!!! Phone #: 1 (562) 485-5550 Address: 3816 Woodruff Ave. Suite 411 Long Beach CA 90808 United States Be warned!!! read more

Ive had several appointments with PA-C Kassidy Williams at Dr. Dezfoli's office and the quality of care I have received has been superb. She's wonderful at listening to my needs and concerns, and offers advice free of judgment. The office staff is friendly and efficient. My appointments always start on time, and the office itself is clean and modern. read more

I cannot recommend Dr.Dezfoli enough! From the moment I walked into the office, I felt cared for and respected. Dr. Dezfoli takes the time to really listen, explains everything clearly, and makes sure you feel comfortable. He is not only incredibly knowledgeable but also kind and compassionate, which makes such a difference when you're dealing with something as important as your health. The front desk staff is also wonderful,friendly and willing to help with scheduling or questions. read more

Dr Dezfoli is an exceptional doctor, especially after our previous disappointing experience with another gastroenterologist . We were Impressed by the numerous 5-star yelp reviews praising his excellent bedside manner and cutting edge expertise. We chose Dr Dezfoli for my husband's care. For background, my husband has been very disappointed in past medical care , always feeling rushed and not heard by most physicians. Thankfully this was not the case this time around! Our first appointment with him scheduled late in the afternoon, exceeded expectations. Dr. Dezfoli informed us that my husband was his last appointment for the day, allowing for extra time. He reviewed my husband's health history, along with his family history and addressed all of his concerns and answered all of his questions. Dr Dezfoli is more than a skilled gastroenterologist; he's a genuine advocate for my husband's health. HIs reassurance and guidance have proven invaluable. For anyone facing similar challenges and in need of a medical professional who listens, cares and takes his time to recognize your needs, look no further. read more

My 77 year old father did not have a great experience. They made him wait much longer than planned for a colonoscopy. This is especially tough because he is elderly and could not eat or drink anything the day of the procedure, and started fasting around 2 PM the day before. It seems ridiculous that patients need to give a one week notice to cancel but it's permissible to have patients waiting hours past their scheduled appointment time. He was told to arrive at 12:30 PM, he was supposed to be seen at 2:30 PM, but the actual procedure didn't start until 4 PM. I contacted the office and spoke with the doctor and hospital staff to understand what went wrong and give them a chance to explain themselves. It was a insufficient apology and finger pointing. My family and I are not happy with how my dad was treated and not very satisfied with the explanation given. Regardless of how busy they are, there needs to be a better system so that elderly folks are not fasting any longer than they should, sitting alone in a room for hours waiting to be seen. I understand that things happen, and they are medical professionals that save lives, which we are grateful for, but I really do think there needs to be some adjustments to allow for some flexibility in the schedule that's not at the expense of other patients. read more

Had a wonderful colonoscopy experience with Dr. Dezfoli. He made me feel comfortable and in good hands regarding my procedure in prep and post information. The staff at St.Mary's Medical Center was also caring from the time I walked in until I left.I would highly recommend Dr. Dezfoli for your for GI needs if you want someone with knowledge ,experience,and kindness . read more

I tend to dread Doctors, their offices and anything to do with doctors. Dr. Dezfoli was lovely and kind, he joked with me and calmed me down and even out on some music I like to relax me. He seems to actually care about his patients. read more

Good luck trying to even get an appointment here. Sent them my info and was told to call back in two weeks to set up an appointment. I've been calling and left multiple messages that they say they'll return but it's been crickets. Called another office in Los Alamitos and got scheduled in 15 minutes for an appointment in less than the time than I've spent trying to get ahold of this office. read more

I live in a rural area serviced by Providence. I'm so grateful that Dr. Dezfoli does travel medicine and it was great to have someone with his expertise and knowledge to perform my Colonoscopy. He listens and his removal of Polyps were all excellent. read more

i had a great experience at Dr. Dezfoli's office today. The staff was friendly and professional, and Dr. Dezfoli made me feel comfortable and well-informed. I highly recommend this office for anyone needing gastroenterology care. read more

I recently called the office of Dr Dezfoli as i had a missed appointment due to getting covid and was charged 50$ for missing the appointment. The office asked me for a covid test result and i mentioned i didn't have due to it being just a quick test and i had thrown that away. Within a month or two i was sent to collections by them for 50$. Just know if you get sick or miss your appointment this is how it will go. While i understand you have to keep your rules doesn't make it sting any less when your sick and you miss something and there is no understanding even after i called. I never met Dr Dezfoli sorry to say. Just how his office runs. Good grief and now you can clearly see how it will go based on the below comment directly from them : read more

Cindy in the office and all of the doctor's staff go over and beyond to accommodate you and make you feel special and cared for. Dr Dezfoli is one of the very few doctors today that really take time to hear you and address any concerns you may have. Very caring and professional. If only all doctors cared as much as he does this world would be a better place. Thank you all! read more

First, I could NOT get a hold of anyone in this office. No phone number, only emails, impossible. Day of: I am on the table and they are hooking me up and stuff in my mouth and I am trying to say please slow down I am freaking out but no one was paying attention because it seriously was like 'just another one of these' and I started CRYING. I don't cry. and no one noticed and I vividly remember Dr Dezfoli with his back to me sitting in a chair on his phone talking about renting office space! I NEVER saw him. He never came over to me while I was on the table. Never saw him after. And when I came to, afterwards, they had a person who did not speak English well....fine! I'm fine with that BUT...not when he tells me they removed polyps and I asked if that's cancer and he said yes but your doctor will talk to you about it-and I couldn't get any reassurance etc..... OMG!!! So you make up your mind. read more

Dr. Dezfoli and his staff are amazing. He is very thorough in his explanations of timelines and procedures. Cindy was a rockstar and got prior colonoscopy records within 5 min. I would highly recommend this office to anyone in need of a gastroenterologist. read more

I feel so fortunate I was able to find Dr. Dezfoli. He was incredibly accommodating to meet with me virtually and his staff is so on top of communications with their patients. It was super easy to communicate with him, get updates and the necessary information I needed. He has incredible beside manner and as someone who often finds doctors and hospitals incredibly anxiety driven he was able to calm my anxiety by outlining everything I should expect and setting the proper expectations. The expectations that he set were just as he said they would be and I honestly feel so lucky I was able to find Dr. Dezfoli and his team. Thanks again! read more

It is really amazing to find a doctor that you can trust from the first visit. I came to this doctor after a very bad experience with another G.I. office. Dr Dezfoli did my colonoscopy (it was not as scary as I thought haha) and I came back for a follow up a few months later for a different issue. He is a caring, knowledgeable and kind person. He actually takes the time to listen to your concerns not rush you out the door. I am so glad I found his office. I never want to go to another gastroenterologist ever again. read more

Rating My Dr. Seper Dezfoli a 5 star. He's kind, respectful, and he's bedside manners are the best. He's very patience with his patients and listen and take his time with your concerns. He goes far and beyond with his job to make sure his patients are comfortable and all questions are answered. read more

The type of care from Dr Dezfoli and his team (the office staff is excellent) is highly recommended by me. So very grateful to find him and received exceptional care from Dr Dezfoli pre and post surgery. His bedside manner was so good, very kind man and assured I am in good hands! Just had my outpatient surgery today; he came to say hello, asked if I had questions for him. Made sure I was comfortable and then in the surgery room again he was superb! Thank goodness for him. Because I'm home now and well. Thanks doctor ‍ read more

Worst experience ever! I set up an appointment for January. I then became very ill and tried calling and texting to reschedule. I could never get anyone on the phone. 7 months later I get a bill of $150 for a "same day cancellation". They do have a 2 week cancellation policy, which I knew about. This is why I started calling as soon as I knew I was not going to able to make the appointment. I even called the surgery center to let them know I was not going to make my appointment, and they said they would try and get a hold of the doctor. Once I got the bill, I reached out to the billing office and requested the bill be deleted, and explained the situation. Their response was that the dr. office said they had no record of me calling/texting. I then sent them copies of my phone bills showing my many attempts to reach someone at the office. I have not heard back and just got another bill stating that it's overdue by 30 days! I have filed a complaint with my health insurance and well as The Board of Managed Care. As mentioned above, my initial plan was to reschedule, but after all of this I obviously won't be going to this doctor. This has been very labor intensive and feels like a scam. Why have a cancellation policy if you don't answer the phone?!? read more

If there was an option to leave zero stars, I would I initially found Dr. Dezfoli via a Yelp! search only to find out he's no longer located in Los Angeles & his office is now in Long Beach. I've been having consistent nausea & vomiting (specifically at night) that I've been having a hard time diagnosing. I made an appointment with Dr. Dezfoli a few weeks ago only to be BOMBARDED with phone calls the morning of my appointment with staff panicking to get copies of an endoscopy report I did back in December (w/ a different doctor before I moved) that had already been mailed to their office & then needing to move my appointment time to an earlier slot day of. After briefly speaking with Dr. Dezfoli, he put me on Dexilant & suggested an upper GI series with Dr. Richard Sukov where a report showed I had something called hiatal hernia. I assumed Dr. Dezfoli would call me back to explain my results, but after I hadn't heard anything, I called his office (multiple times) and eventually got ahold of the receptionist who excused the lack of follow-up by telling me the previous receptionist I spoke to is no longer with the office. I thought sharing this information was unprofessional & unhelpful as I didn't care why, I just wanted to speak with the doctor. The receptionist (I believe, Maria?) called me back shortly after that interaction to "go over my results" in which is told me I'd need another endoscopy, or to see an "ENE." I was confused why she was suggesting another endoscopy as I had just done that in December & not much had changed since then and her response was, "because your systems aren't going away." I asked her to clarify what "ENE" meant and she said I needed to see an ear, nose & throat doctor, but she didn't have a referral to one. When I asked her why she was going over my results instead of the doctor, she told me it was because if I wanted to talk to Dr. Dezfoli, I needed to make an appointment with him. I guess my 4 attempts calling their office previously didn't suggest I wanted to talk to the doctor?! I expressed how disappointed & unprofessional I felt their office was being & this really seemed like a scam to bill my insurance and force me to do invasive procedures for absolutely no reason and no intention in actually following-up with me once those procedures were done. Maria ended our interaction with screaming to talk over me when I proceeded to ask more questions and eventually hung up on me. I'll be looking to file a formal complaint with this office and their practices. I think my experience speaks for itself, but just in case it doesn't -- AVOID! read more

Diagnosing the root of a gastrointestinal issue can be a long process - and a painful one for the sufferer. Thank goodness we found Dr Dezfoli and his wonderful office staff that helped my son find relief from stomach/esophagus/intestinal pain he's suffered with for years. I spoke to Gabby, at the front desk, many times and she always did her best to get my son an appointment, a prescription refill, or a question answered. Dr. Dezfoli is a compassionate physician that doesn't give up, and for this, we are forever grateful! read more

Dr. Dezfoli is an exceptional and unique doctor. His ability to listen to his patients and translate that into the correct type of testing and procedures needed to fix the issue(s) is truly remarkable. His office is organized, billing was done accurately and it was overall a very positive experience during a difficult time. Highly recommend Prestige GI. read more

I went to Dr Dezfoli after feeling like my GI concerns had been dismissed by other GI doctors. My first interaction with Dr Dezfoli was on a video call due to COVID. He was very professional and seemed genuinely interested in helping we sort out my concerns. He listened, he asked questions then proceeded explaining the possible diagnosis. The key word here is "explaining". Dr. Dezfoli always explains in simple terms what could be the issue. We work on a plan together with clear steps. He's also very creative in his approach. He performed a sigmoidoscopy on me that went really well and he was later instrumental in diagnosing some intestinal issues that I had been having for YEARS! I'm now about to receive treatment after years of getting no answered and feeling like I wasn't heard by other doctors. If you're looking for someone who will be invested in your health and who looks at things from a different angle, I'd highly suggest you give Dr. Dezfoli a call. Good luck! read more

Dr. Dezfoli is awesome and a sweet doc! He explained my findings in great detail and made sure to ease my anxiety with his positive approach. I would highly recommend him for all your gastric concerns and issues. Tony S. read more

Dr.Dezfoli has been my doctor for 2,5 years by now. It is his extensive expertise accompanied by immense patience and detailed approach that helped me to accept the fact of having the autoimmune disease and learn how to live with it. I really appreciate his willingness to listen and discuss his patient's condition. For him there's no such thing as a silly question or weird description. Dr. Dezfoli knows when to give you some time to mull over information, or when to nudge you gently to a much needed procedure. He doesn't mind old school treatments but stays on top of the most modern and progressive research - in case you're ready to consider this option. I'm very grateful for Dr.Dezfoli to be on my side in this trying journey. read more

Dr. Dezfoli is my mom's GI doctor. I cannot say enough kind words to him and his wonderful staff, who took care of my mom. Dr. Dezfoli is attentive to his patients, listens to all their concerns, and answers any questions. My mom had two GI procedures with Dr. Dezfoli that went so smoothly. She is happy to be his patient. The front desk ladies are very helpul and welcoming. Special thank you to Gabby! Dr. Dezfoli and his team are amazing healthcare professionals for whom the health of their patients is paramount. read more

Incredible bedside manner. Caring and attentive. I was very nervous going into the procedure, but within moments of Dr. Dezfoli explaining what was going on, I was put at ease. Clear communication. I hope I don't have to see him again, but if I do, I know I'll be in good hands. read more

I had the pleasure of meeting Dr. Seper Dezfoli today at Kaiser where he works once a week. It was, for me, an emergency appointment because of what I was experiencing. I was nervous and within just a couple of minutes after telling him what was going on, he cracked a few jokes and broke the tension. It wasn't that he didn't take me seriously, but rather he wanted to ease my stress and bring down my tension. It worked!! He was very attentive and explained each step of the easy non-painful examination so I would know what to expect. And afterwards he made me laugh again and also assured me that with some medication, I would be back to usual. He is incredibly professional, caring, super funny and patient. ALOT of Physicians could learn ALOT from his style of care and communication with patients. I would recommend him to anyone needing a GI doctor. You won't be disappointed! read more

Dr. Dezfoli took care of my husband in the hospital and that's how I met him. My internist also recommended him. It is now almost 4 a.m. and Dr Dezfoli just returned my phone call because I'm getting ready for a colonoscopy later today and my first preparations took to have bowel movements wasn't working. He returned my call and had a couple of suggestions and assured me everything should be fine for my procedure. Thank you Dr. Dezfoli. read more

I was going to be selfish and Not share my review with Dr Dezfoli. We had our first appointment yesterday and it was PHENOMENAL! He went over everything in details. He gave some peace of mind. Dr Dezfoli is really caring. It's like I told him, I truly wish there were more doctors out there like hime he spent almost an hour with me and getting to know me. Truly, truly Grateful! read more

I don't know how this wonderful doctor can stay so organized and give such excellent, undivided attention to his patients. My problems feel so complicated and I've been feeling horrible for months but every moment of my experience in Dr. Dezfoli's office has been reassuring. He thoroughly reviewed my GI results, as well as results from another member of my healthcare team who he works with, he even contacted my primary care doc and I feel like I am being cared for by all of them as if I'm on a freaking TV show where everyone cares about patients! Why are doctors like this so rare that they are emulated like a fantasy you watch on TV?!?? Every patient should be cared for this way. The staff in his office is extremely friendly and they all seem just as grateful as I do as a patient, to be working for him. This is the care that I've prayed for. While my situation is not totally resolved yet and I'm being referred to a urologist, I finally feel like I am on a path to healing and feeling better. If you need help in the digestive and internal areas of gastroenterology, look no further. Here is your doctor. read more

Great doctor and really easy going bedside manner. When I first started going to Dr. Dezfoli he recommended a change in a medication I had been barely tolerating for many years. It was a life changer! No other doctor had thought to prescribe it. I highly recommend Dr. Dezfoli and am glad to have found him! read more
