I've been coming here for over two years, and I can't say enough good things about my experience--especially with Dr. Jennifer Gong. Dr. Gong is outstanding. She's professional, knowledgeable, personable, and genuinely takes the time to listen. She doesn't make you feel like you're just the next appointment on the schedule. She pays attention to what's bothering you, explains what she's doing, and adjusts the treatment based on what you actually need. The quality of care has been consistently excellent, and the entire office makes every visit comfortable and welcoming. After more than two years as a patient, the fact that I continue coming back says everything. Dr. Jennifer Gong has earned my trust, and I highly recommend her to anyone looking for excellent chiropractic care. Five stars without hesitation! Lamont and Deb Watson read more

This is a very well run office with knowledgeable doctors and helpful staff. They assessed my medical issues, developed a plan of care and began treatment all in the same visit. Dr. Hagan went over my x-ray results with me and gave me one of the best adjustments I've had in my life. I look forward to my ongoing treatment at Hagan Chiropractic. A+ read more

Having back pain & some neck pain brought me to Dr.HAGAN's Chiropractic office. I found him through my insurance & am quite pleased with the service & front desk operators & administrator. Especially when I made several inquiries regarding insurance, cost & parking. The administrator patiently & informatively answered all my concerns. There was no push to purchase a pre-paid plan, just simply what I felt I needed. I've only started going to this office for a few months (since Oct.25' ) & have found some relief. So I would recommend Dr.Hagan & his staff of chiropractors for their practical assessment & service. read more

I have been a patient at Hagan Chiropractic for over 20 years. Because of a spinal condition (Had since birth), that caused swelling, mobility problems, and excruciating pain, I knew I needed a place that I could trust to give me the proper care I desperately needed so that I could live a somewhat 'normal' life and function daily at work, school, with family, and alone. Hagan Chiropractic is that place! Yes, I've tried others in and out of the area, but none have even come close to the excellent care I receive! He and his staff are genuinely caring, detailed and attentive, and efficient in providing the care you need.... Not just with disabilities, but also with injuries, etc. Dr. Hagan and his staff take a hands-on approach and actually explain and teach you about your body and what to do to improve your health with 'preventive' measures, encouraging you to walk, managing your diet, exercise, and they also offer massage therapy and have exercise equipment for their patients right there in the clinic! Kudos to Dr. Kent Hagan and his staff in Hayward California! The #1 place to go for excellent health and wellness care! C. Fisher-London read more

After I got a very bad flare (I have rheumatoid arthritis) my rheumatologist did steroid shots and increased my meds....nothing worked. I could hardly walk, could barely turn my head....every joint hurt. I started looking for other options and my insurance covered chiropractor. I started going to Hagen on April 15, 2025. After a couple of weeks I could put my chin on my shoulder. As weeks went by I continued to feel better and I can't could move with less pain. I'm still going every other week to keep my body moving. Dr Tomcik is fantastic and I love the front staff....they are always so helpful and friendly. I also love Anna who gives me electronic stimulation before I get adjusted.... really helps a great deal. I recommend this office.... everyone is excellent. Check this place out if you need a chiropractor for an injury or even for regular adjustments....it will make you feel fantastic. read more

Great care! I'm a regular patient and love the care I get from the doctors at Hagan Chiropractic. Dr. Tomcik helped me out with an adjustment that took my back discomfort away!! Thank you!! read more

I love this place! The team is super friendly and very organized. They have been helping me for years and as long as I live in the area, I will not go anywhere else. read more

I have been coming here off and on for about 15 years. I was first introduced to this office when my family and I were rear ended. It took a bit of time, but they fixed us right up! Here I am 15 years later, and some old sports injuries have come back to haunt me! I was at a point to where I could not lift my left arm at all! With the assistance of Drs Gong, Hagan, and the drs on staff, my mobility and strength is returning! That front office is 2nd to none! Fina and Emily are the nicest and friendliest EVER!!! Always so cheerful and helpful! They are the epitome of grace under pressure and the glue that keeps that office rockin' and rollin'!!! I've been there when it's jam packed! They take everything in stride and kind and professional to each and every patient they come in contact with! Great place to come to, to get yourself right!!! read more

I had my first visit with Dr. Tomcik, and the visit couldn't have gone better. The entire staff at Kent Hagan Chiropractic were all so professional, while also being so sweet and caring. I'm actually 8 months pregnant, and have been struggling with back pain, and Dr. Tomcik made me feel so comfortable. I'm already looking forward to my next appointment, and will continue to receive care as Chiropractic care helps with my pain, and with my overall posture excluding the pain! read more

Dr Hagan is the best he has great knowledge understand patients how to fix the pain he's like a magician . Office is great staff is professional . Definitely recommend read more

Dr Strange is Alive and Well Here!! If you're not a comic book aficionado worry not, its just a reference to a team of highly gifted team of Physicians that are uber talented and practice miracles day in and day out. Amazing practice well worth the price of admission as health is priceless read more

It's been many years since I have received an adjustment and care from a chiropractor. Making the decision to come to Hagan Chiropractic was certainly one that I will not regret! The staff are very friendly and in terms of time they are very flexible and tend to you in a timely manner. After just my first visit I already felt a difference ! My journey for better posture will be a long one but I'm glad that I have someone to count on for my eventual better posture transformation! Overall I recommended this place! read more

I've been going to Dr. Hagan's office now for several years. The combination of electro therapy and adjustment are keeping me in good health. Generally I go once a month for maintenance type of treatment. The staff and Doctors are just fabulous, friendly, knowledgeable about what this patient's needs are. read more

This place was disappointing, specifically the chiropractors are unprofessional and lack bedside manner. I ended up feeling worse than when I went there due to having a different chiropractor adjusting me. I was not made aware prior to my appt beginning that there was a change in dr and the dr who adjusted me was rough and pulled my hair while adjusting me. Long story short, I left with more pain than I started with. When I returned at my next appointment and discussed with my original doctor, her demeanor was extremely defensive, uninterested and unapologetic. There was no concern for my pain and or the weird switch that I did not know about or consent to. One star for the desk staff that was friendly. read more

Referred here by a coworker and now I'm definitely going to buy him lunch tomorrow for the amazing recommendation. Great first time experience, made another appointment for tomorrow. Came in with 9/10 neck pain, and since the appointment the pain has subsided. Pain is about 3 or 4 now!! Really enjoyed my adjustment appointment, the service was quick, efficient and successful. Doctors and staff were very kind and informative . Can't wait for tomorrow. read more

I've been meaning to come here after hearing my sister praise about it for a year, but a car accident definitely assisted me to it quicker! I was glad to know you can have x-rays, treatment / adjustments all in the same place. It's so hard to find that all in the same building these days lol. The staff is so friendly and sweet, they walk you through the process of everything and ease you into the routine. I've had the pleasure of meeting Dr. Gong and Dr. Tomcik - they're both great! There's a good presence of familiarity between staff and patients = good customer service. This is worth a 45 - 60 min drive for me. read more

First time being with a chiropractor, been suffering from jaw pain, jaw locks, and facial/neck pain. 10/18 i had an appointment and the staff are so nice and caring. It started off with an evaluation then an exam/ x ray. Doctor gong made me feel comfortable and calm due to being anxious. Super great and will be coming back hoping to get fixed ! Therapy session 10/10 10mins of heat pad and electric magnetic therapy? Forgot what its called but amazing with a free icy cool back rub After it was time for the adjustment, I DIDNT KNOW I COULD CRACK LIKE THAT. Amazing felt great and cant wait to continue the rest. read more

I've been coming to Kent Hegan Chiropractic for a little over a month. Location: Busy intersection of Jackson street and difficult to get to in the commute hours. I recommend going around through Soto and coming in through the back parking lot. Therapy Services: Ana and Alondra are amazing! Ana is very sweet and takes her time to make sure you are comfortable. She explains everything ahead of time and checks up on you often. Alondra gives the best massages out of all the therapists. All are amazing but I always feel better after her massage. Adjustments: Dr. Gong, by far one of the best chiropractors I've ever been treated by. She is gentle yet effective. She always asks how I'm doing, always asks me for progress updates and takes her time making me feel better. I'm still on the mend but feel that her treatment plan is helping me slowly recover. I highly recommend that you check out this office. read more

After a car accident, I was sent to DR. HAGAN chiropractors office. There was an extensive thorough intake in which they even took xrays. They have multiple massage therapists who treat me every visit prior to sending me to the Dr. to get a thorough adjustment. I've gone to Many Dr's offices in my life. DR. HAGANS office is literally the Very Best Dr.s office I have ever been to. Especially Dr. Tomcik! They have the most efficient system I've ever experienced. They are always upbeat, professional and offer EXCELLENT service from the receptionist to the owner (it feels like what customer service used to be). I feel like i am going to a spa in Beverly Hills. I am feeling better slowly but surely with ever appt. I would Highly recommend Dr. Hagan Chiroprator's office to any and everyone! read more

This is a terrible place to receive treatment. I dealt with Maurine Hagan, wife of Kent Hagan, who has so many problems with bedside manners and communication. She does not communicate! The care is awful and Maurine Hagan is self-absorbed. She is concerned about her tennis match and does not want to show up to office. That means no care for you the client. She has limited knowledge and it is only at a remedial level. Please do not come to this place because you will be treated very poorly. read more

They take care good of you they make sure you are welcome. They do chiro and massage. Dr Gong is amazing even there stuff are kind and nice.

I was referred to this place by the Joint because I was involved in a rear ended car accident. I never realized how much back pain I was in until I came here and finally got massages and adjustments. The staff is very welcoming and friendly. They keep the place clean and sanitized. They also play great music :) read more

Absolutely recommend their office. We were referred the chiropractic office by our lawyer Mervin after being in a car accident. The entire office is great. They make sure to explain what and why they are treating you for whatever reason they need too. They are realistic and make you feel comfortable while your being treated. If you need an alignment or therapy this is the place to go to. read more

Excellent and attentive staff, my favorite part is that they communicate clearly with me and answer all my questions so I know what I'm getting done and why. read more

This is a great practice Dr. Hagen and his staff are super friendly and helpful. They really work with you on the issue or problem you may have. You get results from the experience here and they explain everything very well. read more

I am relatively new to the Bay Area and Hayward. My wife and I moved here from San Diego during the peak of the pandemic last year. I was experiencing neck pain from working from home this past year, and I finally got around to finding a chiropractor. My chiropractor in San Diego did a combination of physical therapy and chiropractic adjustments, so I was looking for someone who specialized in both. I found Dr. Hagan from my insurance portal and double checked on Yelp. Getting my first appointment scheduled was a breeze. You can contact them via website, email or phone, and someone from their front desk will call or reply to your email within a day. I've been going to see chiropractors on and off my entire life, and this was the first time getting an X-ray. It's reassuring that the treatment plan is derived from the investigative evaluation they perform. Dr. Hagan's practice is the first one I've been to that has a full team of massage therapists and chiropractors working together under the same roof. Staff are very friendly and make you feel welcome. I was very impressed with their seemless system of therapy and adjustments. I've been getting treatments for about 3 weeks now, and I can honestly say I'm very happy with my decision. Edit: COVID-19 safety protocols in place. Mask mandate in place and hand sanitizers are available. read more

I went here a couple months ago and honestly I thought this would be my permanent chiropractor in the first session. They started with X-rays and a general check up which no other location had done for me. They did find my neck and upper back needed the most help so they set up a plan for me. On my second session they were going to go over the details in depth but I sat in the office for so long I had to go. I was 15 mins early and they brought me in the office right on time and I still had to wait 15-20mins. I walked out and rescheduled. When I came back he explained in detail what the plan was. I was all for it but when we went to do the adjustment all he did was my neck. He spent MAYBE 5 mins on it if that and told me it was done. Before I laid down I did mention bc I work in office my lower back was killing me that day he nodded and again only focused on my neck and moved on to the next customer. Yes, customer not patient. That's how he and his entire team made me feel. They of course push their EXTRA cost massage every single time. No matter what the "Dr" just did for you they will push the massage for an extra $30. I cancelled my last appointment and never plan on rescheduling again. He doesn't seem to care to take care of my entire well being and I don't care to keep wasting my time and money there. read more

They make me feel like a new woman once they align me! The staff are all so kind and they are following guidelines to keep everything sanitized for everyone's safety during this pandemic Thank you guys sosososo much! read more

I was looking for a chiropractor that was located near by and I'm so happy to find this place! The staff is so wonderful and I've been seeing Dr. Gong and recently seen Dr. Tomcik who are so great! The business does take in insurance which is helpful. Everyone is friendly, welcoming, and caring. I've had my first consultation with Dr. Hagen and he thoroughly discussed how everything works and Dr.Gong had done my X-rays and went over my treatment. Everything is ran very efficiently and they are so accommodating and flexible. 10/10 recommend read more

The people at Hagan chiropractic area very professional people ! They explained all of procedures and what's going to happen Taking any fear or apprehension I had completely away and because this was the first time that I've been to a chiropractor it was a lot of apprehension on my part !!! appreciate everything the Staff has done for me !! I'm feeling a lot better already compared to what I was feeling !! I was sleeping on the floor due to the pain in my back !! I wish I had gone there six months earlier it would've saved me a lot of grief and Pain !! SF JONES read more

I have been a patient for many years. I initially came in because of severe neck pain, low back pain and headaches. Within the first few sessions, I began feeling noticeably better. My quality of life improved over the years. I now come in for routine treatment and to assist with an ongoing battle with migraines. Dr. Eric Hall is very personable, and takes a more natural approach to treating the body. He makes me feel relaxed and watches my body carefully for any tension and reactions. I am very please with his care and knowledge. He is an asset to Hagan Chiropractic. The gals in Therapy are very friendly and take the time to find out how I'm doing in my personal life, and make an effort to connect with me. It's a very welcoming environment. Dr. Hagan is very knowledgeable and in tune with his practice. He has been mindful of my disability and so long as I have updated him on my health procedures, he has adjusted his treatment to cater to my physical limitations. One day he had to adjust me while seated in a chair after an abdominal surgery. I really appreciate the flexibility in treatment to meet the patients needs. I use to solely seek treatment from him until I met Dr. Eric. Both approaches are unique to their version of healing, and depending on how my body is feeling, I will choose to work with either doctor. With all of the treatment I have received through the years, I hope to be a limber, flexible, old brad one day. read more

Absolutely the best chiropractors around the East Bay. Everyone working here from Doctor Hagan to the receptionists and message therapist are such a joy to work with. I feel so much better and look forward to visiting every time. Look no further, come here! read more

Great service staff is super friendly there on top of it , and the doctors are great they explain the process with detailed and make you feel comfortable. read more

I've only been here a handful of times and each time it's gotten worse. It doesn't matter when your appointment is, expect to wait a minimum of 35-45 minutes for a simple adjustment. I schedule other appointments an entire hour after and still don't make them. It's ridiculous to expect someone to come in multiple times a week and wait so long for an adjustment that takes less than 5 minutes. I waited 40 mins today and ended up having to leave. It's too much of a waste of time to be able to excuse it. I will be looking for chiropractic care elsewhere. read more

I made an appointment online for May 31, 2023 at 3:45 pm. Arrived a few minutes early, filled out the necessary paperwork and turned it in. I then waited, and waited, and waited for 50 minutes without any sign of being seen by anyone. A lady came out, spoke to the receptionist about what appeared to be my file, she looked at the clock and said hopefully we have time. Not sure why a business would overbook other than to maximize earnings at the expense of upsetting customers. Waiting with an appointment for over 50 minutes and only God knows for how much longer before I was seen is just not acceptable. I am not a very demanding person and understand that when one is a new patient it takes time to be processed but we are talking about waiting for 50 minutes without any feedback until I got up and left. Not the way you run a business. My review is probably not important to most but if I can save a few people from wasting their time. Its good enough for me. It should also be noted that while I was waiting a man came in to serve a Subpoena for the Chiropractor. Granted there could be a number of reasons for the subpoena. Many of the reasons could be negative, making them concerns to patients. read more

I see Dr. Jennifer Gong there and she's awesome! She's professional and asks how I prefer to be adjusted (by hand or with device they use). I'm petite so it's nice to get adjusted by a female that won't treat me like I'm a football player. I've experienced with past chiropractors. She's gentle yet effective at getting rid of my migraines when I'm out of alignment. The staff are sweet and efficient. I saw Dr. Tomcik there once who is also good. I highly recommend them! read more

After a long hiatus I was overdue for an adjustment but my insurance hates me and doesn't cover chiropractic care ]: For some odd reason I was allowed 12 medically necessary visits in AZ but I get nothing in CA.. So after waiting 3 months I finally went in today because I was experiencing more pain than usual.. Dr. Hagan is currently holding a new patient special where you receive a consultation, complete examination, x-rays, and an explanation of treatment options for $37. For an additional ~$45 you can receive treatment and get your back adjusted that same day! For people like me who are members of evil insurance companies, it is more cost effective to sign-up for a package deal to reduce the overall cost of care.. If you pre-pay for 12 visits the cost of each adjustment is reduced to $39.60 so you save $60 in the long run.. This is great if you can swallow the $475.20 cost up front but not helpful if you're strapped on cash.. They also have $200 monthly payment plans if you pay for the full price adjustment to help out their clients.. My first experience here was great! The receptionist, massage therapist, and both of the doctors were all very friendly and approachable.. I first had a consultation with Dr. Hagan, then an examination and x-rays with Dr. Gong.. While they developed my x-rays I received electrostimulation therapy and a mini-massage in their therapy room.. After that I got my back adjusted by Dr. Hagan and I was good to go! Unfortunately I found out my back suffered a lot during the 3 months that I neglected to get it adjusted so I'll be going through an intense therapy/adjustment schedule for the foreseeable future ]: At least the office and employees are nice though so it's not a bad place to have to go to [: This is by far the largest chiropractic office I have ever seen! They have everything you could possibly imagine, including exercise equipment.. I thought that was very unique and progressive.. read more

I absolutely love coming here! My lawyer recommend this place after our accident, and my husband I will continue to come on our own. The place is clean, the staff is extremely nice and personable. They seemed to remember every detail and follow up on conversations. I felt like they truly wanted us to get and feel better and they were educating us in the process. read more

I was not told that Dr. Hagen was out on leave and I wish him a speedy recovery. The associate chiropractor was caring, and did the job, however I am a big and tall fellow, built big and strong, no match for the young lady a third my body weight. Normally I would feel like I got hit by a truck, with all the cracking and popping, but not this time. I'm going to take a break from this place. read more
