Patient Testimonials

“Was referred here by a friend and could not be happier with my decision to come in.  Dr. Jeremy is very prompt and courteous and has done a great job putting you at ease during the pandemic.  The adjustment and recommendations were excellent, and I left feeling much better than I arrived.  Looking forward to many more visits.  Will definitely be referring more of my friends to stop in and see him!”

“Dr. Jeremy was very welcoming from the start. It was my first time seeing him today and he started with an assessment with my posture which made me feel confident that he would tailor the treatment to me. Throughout the whole appointment he was very accommodating and made sure to communicate with me what he was doing and why which helped me understand my body a little better.”

“I competed in powerlifting at a young age and unfortunately it took a toll on my body.  I used to suffer from neck pain due to a slipped disc at my C6-C7.  I would have to continuously get cortisone injections every 6 months to help with the pain that was unbearable.  Dr. Jeremy has been treating me for the past 4 years and I am glad to say I no longer need routine injections due to his personal care and treatment plans.  I also need assistance with my lower back pain and muscle spasms from time to time and every time I go in, I leave feeling better with the treatment and assisted stretching that is provided.”

“I have had many sports related injuries through the years, requiring many chiropractic visits. Now I am just old with chronic neck and back issues. I recently moved to San Diego and was in need of adjusting. Dr. Jeremy was professional, knowledgeable, trustworthy and caring. He spent more time listening to what my ailments were than most take for a whole visit. He took time to really evaluate and come up with a plan to get me back to feeling healthy again. I would whole heartedly recommend Jeremy. He provides amazing service and his prices and pay structures are very reasonable. It ended up being quite a bit cheaper than even going through my insurance. Try him out!”

“I've been to a handful of chiropractors throughout San Diego for treatment if chronic neck pain. Upgrade - Body Conditioning is hands down the best. Dr. Gayner is an incredible doctor. After a detailed movement analysis and chriporatic evaluation, Dr. Gaynier was able to diagnosis the cause of my neck pain in which I have been struggling with for YEARS.

My treatment includes monthly chiropractic adjustments combined with massage. Years of pain nearly gone and continues to improve with every treatment. Hands down the best chiropractor in San Diego!”

“Dr. J rocks! Has helped me immensely with my sciatica. I highly recommend him and I've been to many chiropractors in my time!

“I just completed my second treatment with Dr. Gaynier at Upgrade Body Conditioning and it was phenomenal! He did a combo of cupping, massage, and chiropractic adjustments. Right away I experienced significant pain decrease and more flexibility. I'm hooked and can't wait to go back next week. Dr. Gaynier is very generous with his time, talents, and knowledge of the human body and how to heal it. Along with that, his new office is spacious, welcoming, and has ample street parking.”

“Severe arm and back pain.  Dr. Gaynier got me in fast and gave me treatment.  Very knowledgeable.  Pain subsided about 70% after first visit!  Looking forward to having regular adjustments.”

—Brian M.

“I have been to chiropractors before and it seems like their top priority is to sell you more sessions.  I gave Dr. Jeremy a try and he was caring, knowledgeable, had a holistic approach, and explained all aspects of his exam and assessment. His recommendations included a series of exercises that were available on a website with instructions and video examples.  He also offers single sessions or a variety of membership packages for ongoing maintenance that are very reasonably priced.  Following the adjustment of my lower back, I felt great!  Thank you Dr. Jeremy!!!

I have been seeing Dr. Gaynier for almost a year now.  I came in initially for lower back pain.  After the initial back adjustments and recommended exercise program (complete with videos), my lower back issues were resolved.  However, because of his holistic approach to chiropractic work and focus on total body wellness in general, I decided to continue with an ongoing membership program.  A regular "tune up" with this very caring doctor is an important part of my overall health and wellness plan.  Thank you Dr. Gaynier!”

“I AM SO HAPPY!! I had my first adjustment and massage Combo here at Upgrade with Jeremy. Let me just say, my body has never felt this good in a long time. You should absolutely come here!! Jeremy is an expert chiropractor and massage therapist. He can name every muscle in your body, and tell you exactly what it does and how it works. We did a very thorough initial assessment for any body alignment issues. Then, he showed me what my issues were and how to correct them.  I signed up for one of his monthly deals because I'm making an investment in my body and so should you!!it's totally worth it! Do it! Btw..Jeremy is super professional, extremely smart, kind, and really awesome to be around. I look forward to my next session with him.”

—Dominika P.

“Dr. Jeremy is the best!  I am a hairstylist, so needless to say my body takes a beating being on my feet 12hrs a day. I go to him for adjustments and massage. He is affordable, kind and very knowledgeable! He uses modern technology to recommend workouts and stretches to help with any issues you may be having. I highly recommend him and all he offers!”

—Sarah P.

“I've recently switched over to Dr. Jeremy after being with my previous chiropractor of nearly 10 years.  Jeremy's office is close to my home and I decided to give him a shot.

He did a posture analysis that was very helpful in showing me how to stand in a more back-healthy way and he also gave me a number of stretches and strengthening exercises customized to assist me with this.  

I started by getting a chiropractic adjustment and he's great!  Then, I got a massage and was really impressed.  His knowledge of the body from a chiropractic perspective definitely benefits him in giving an amazing massage!

And to top this all off, a person can purchase a service on its own or buy a package.  I work in a chair all day and tend to have quite a bit of back and neck strain.  So, I've purchased a monthly package which allows me to get a chiropractic adjustment weekly and then get a massage once a month. Getting regularly scheduled adjustments and massaged have made a ton of difference in my posture and has relieved so much pain in by back and neck.

I highly recommend him!”

“What a great experience and office!  I used to see Dr. Jeremy Gaynier in another part of the country ... years ago.  I was sad when he moved his office to San Diego, and so when I happened to be in San Diego, I made it a priority to see him.  Always accommodating, Dr. Jeremy fit me in on a Saturday morning despite short notice and his busy schedule.  As I have come to expect, Dr. Jeremy is a highly skilled chiropractor.  He's very adept, and always provides effective chiropractic therapy (massages, adjustments, etc.).  I have a series of medical issues/pain, and I felt incredible for quite some time after my visit (much better than what other chiropractors have been able to accomplish) -- thank you.  Atop this, Dr. Jeremy's rates are very affordable; his studio is clean and well equipped; and he's incredibly polite, friendly and patient -- he takes his time to thoroughly explain his process and answer the multitude of questions I had.  I felt very comfortable and relaxed throughout the experience.  If you are anywhere in the San Diego area, I strongly recommend making a trip to see Dr. Jeremy -- it was well worth the trip, and I'll be back.  Thanks, Doctor.”

“I've been seeing the same chiropractor for 10 years and finally decided to change, and Jeremy has been great! He provided me with so much useful information and he really made the most of the time I was there for. I've tried other chiropractors and feel like some want to just get you in and out quickly, but he gave me a quality adjustment that left me feeling great.”

—Brent G.

“I had a major sciatica attack this weekend after working out. Had not had an issue in eight years, and went to Dr. Gaynier for relief. After one session, the pain of the last three days was over. I was amazed the technology he used to diagnose the problem, and signed up for his chiropractor/massage monthly plan, and amazed how inexpensive it is. I would recommend highly Upgrade, Dr. Gaynier and his program.”

—Gregory P.

“Best massage experience ever!  I could tell Dr. Gaynier knows the body which led to the perfect pressure and unique technique.  I could completely relax knowing I was in good care and not need to guard sore areas.  I will be back for sure!”

—Bryan D.

“After 25 years of moderate/severe back pain and treatment by medical doctors, accupuncturists, and other chiropractors, I decided to see if Dr. Gaynier could help me. After obtaining a full medical history and evaluation of my symptoms, he developed a customized treatment and exercise plan. Seven weeks later, my pain level has decreased from 6/10 to 0/10, and I feel like I'm finally getting the help I need. The membership plans are extremely reasonable. I've signed up for a monthly membership plan and will keep it going indefinitely. The investment in my health is well worth it. Thanks Dr. Gaynier!!!”
