Services
Dr. Jack Ricci earned a Doctor of Chiropractic at Life University West. After his graduation, he became an associate doctor in the Bay Area. His next move took him across the pond to Ireland, where he took over a practice for a doctor who was on sabbatical. There, just north of Dublin, he worked for some years.
Before becoming a chiropractor, Dr. Jack's life was on a completely different track. In childhood and the military, before he attended college, he suffered from back injuries. The only solution given to him was drugs or ineffective physical therapy. During his undergrad years, he was at UC-Davis, studying to become a medical doctor.
If you're new to chiropractic, you might be unfamiliar with what it involves. Chiropractic is a natural health care modality that helps you feel better and function better from the inside out. Dr. Jack works with the structure of your spine and your central nervous system. In addition to adjustments, he provides wellness coaching, nutrition and spinal decompression.
An athlete lives a different life than your average person or weekend warrior. At Core Chiropractic, we have a keen understanding of the demands your body has placed on it during rigorous training. We'll put in the work with you so that you minimize your time on the sidelines. Our care involves looking at your lifestyle, practices, metabolism and the structure of your body for a comprehensive approach.
While Dr. Jack was attending Life University, his wife became pregnant with their daughter. She was born around the same time Dr. Jack graduated. Because of his unhealthy childhood, Dr. Jack lacked confidence in his ability to raise a healthy child. During chiropractic school, he learned that many chiropractors specialized in pediatric care.

This is how one of your employees treats people outside the practice - he threatens Jewish persons and compares COVID vaccination to the Holocaust.

I went to see Dr. Ricci after I slept in a position that misaligned my neck causing pain for days. I received an adjustment as well as a lot of good information on how to prevent it from happening again.
He is very informative and a great chiropractor. He uses up to date equipment, and a gentle approach.
Awesome experience.

Dr. Jack Ricci is a great chiropractor. We met as a result of an accident I had at my work. The reason for a 5-star rating as that Dr. Jack provided me with an alternative to pain meds to reduce pain caused by bulging discs in my neck. Because of him I am more knowledgeable about the physiology of my body in particular the neck and shoulder area. Thank You !!!

Dr. Ricci is a Chiropractor’s Chiropractor! We Chiros all aspire to being such.
I’d traveled from Mexico by stressful flight then drove to Nevada City & hadn’t been adjusted for months! I was pretty locked-up & Doc sized the situation up quickly.
As a seasoned sports doctor, he professionally assessed the problems as connected through my kinetic chain. He was specific in his adjustments & recommendations & turned my power back on! I left feeling 100% better!
I highly recommend Dr. Jack Ricci & will definitely return for more whenever I’m back in this area.

A friend of mine said I should include my review to include his chiropractic location in Nevada City too. I've had Jack adjust me at his old location in Kentfield. I had alright results. I wanted to give him some business as an acquaintance through a local group of bikers. He was nice and friendly, very likable. The last time I saw him in Mill Valley the session was not positive. We spoke about the current state of the pandemic (early stages) and he became clearly agitated as I spoke about my perspective. He was not present in the moment, he shut down almost immediately, saying that other

I visited Dr. Ricci while we were visiting in Nevada City. Traveling had left me out of balance and feeling a little snarly :). Doc has a way of focusing and "knowing" where I needed help. I got a great adjustment and left feeling refreshed and more energetic. Highly recommended as a safe, confident and clean guy.

I've been meaning to write this review for quite some time, as my quality of life has drastically changed since I began seeing Dr. Jack 14 months ago. I could easily write a novella singing his praises, but I'll refrain and just tell you about my experience...

I had suffered from excruciating pain for years, mainly between my shoulders, in my upper back. After seeing various chiropractors regularly for years, I had never really gotten any answers about the culprit. More so just "come see me again next week" and minor relief that would last a week or two at best.

Dr. Jack has been a blessing to our family, in so many ways. He's an intelligent and intuitive practitioner who combines personal experience, with medical training, with a holistic approach. Not only will he know how to fix what's ailing you, but he knows enough to know how to offer preventative care for the things creeping up around the bend. He combines in-office care with very specific, specialized instructions for home care & diet & movement - and if that weren't enough, he also has our 7 year old shepherd mix, 4 knee surgeries later, walking better than he has since

Moving to the Nevada City area from the Bay Area back in September of 2017 I was concerned I wouldn’t find a good chiropractor. I have seen a lot of chiropractors over 40 years and of course have had the good, and the bad. I needed a truly hands on doctor whose top concern was my good health.
I was was completely wrong to be concerned.....I didn’t find a good chiropractor, I found a great one!
Dr Jack is definitely a great chiropractor with each of his patients health and well being at the very top of his priorities. He is a devoted health professsional I am proud call my chiropractor.

Dr. Jack is truly awesome! I wish I had found him a year ago when I first started having sciatica. He did a thorough assessment of my spine and sent me for x-rays to get a complete understanding of what was causing my pain. He created a specific treatment plan to help me get out of pain and heal my discs. I have learned so much about my spine and am very grateful that he has so much experience, knowledge and a passion for educating his patients on spine health!

Dr. Ricci is a fantastic Chiropractor. For years I've been exploring different offices and many techniques to make my back pain go away. I'm very happy with the treatments I'm receiving at Core Chiropractic. I'm two months in now and I'm noticing a big difference. I know that I'm in good hands and on my way to healing success. Give him a shot and you won't be disappointed.

Had a slight dislocation in my shoulder and checked out the reviews while looking for a local practitioner. Dr Jack's reviews were great and he is just 1/2 mile from my home. He called me back within an hour of my leaving a message. He had had a cancellation later that day and I filled it.
He was personable, knowledgeable and thorough in his pre-treatment exam. He painlessly treated my issue, gave me some at home self-treatment instructions and a follow up appointment for 3 days later. My shoulder was 80% better by the time I returned. After my follow up treatment I had much better mobility

Dr Jack has been my (and my children's) Chiropractor for many years now. I first started getting adjusted when I was pregnant with my daughter. The adjustments helped to relieve some pretty serious back pain I was experiencing during pregnancy, and helped get rid of the occasional headache.

I have also had my children adjusted since they were young and they've grown up very healthy because of it. He uses methods that are very gentle.

I feel like now that I stay on a regular adjustment schedule, I'm overall much healthier. I rarely have any pain or major problems.

I can't say enough about Dr Maria. She is such a passionate human being who has dedicated herself to becoming an incredible healer and chiropractor. Her adjustments are effective and highly skilled and her ability to listen to my body is amazing. I love the way I feel after receiving an adjustment from her!

Jack is a remarkable chiropractor, and an exceptionally lovely person too! His powerful presence is immediately safe and inviting, creating space for his clients to fully relax into his care. HIs technique is deeply knowledgeable across a multitude of modalities. His touch is precise, gentle, and intuitive. The quality of his work is extraordinary. At my very first appointment, I felt my spine align (with ease!) in a way that invited release and opening in areas of my body that I hadn’t even considered might be freed by a chiropractor. Tension melted away, and I was left open and uplifted - my

Dr. Ricci is awesome!! There are very few people I would allow to work with my body and he is at the top of the list! During times of injury with extreme pain, his treatment helped me to limit and eliminate opioid use.

I've had a lot of bad luck with chiropractors. I've been injured, charged outrageous fees, and given grim prognosese. Dr. Jack is the chiropractor I was always looking for. Here's 5 reasons why he is the best chiropractor I have ever been to.

FREE CONSULTATION. Dr. Jack talked with me for 30 minutes about my long, sorted chiropractic history. I have been charged over $100 by two local chiropractors for the same service.

UTILIZES X-RAYS and MRI's. He did not want to progress in my treatment until he had all the information. Dr. Jack can recommend low cost x-rays. $85 for digital

Dr. Ricci is paying careful attention to cervical issues in my neck. He had me get X-rays to confirm the best course of action to take concerning my treatment. I respect his commitment to my health and healing. He is focusing on things that I can do daily for my spinal and overall health. He is wonderful educator as well as practitioner. I recommend him highly!

Dr. Jack is phenomenal! I have had trouble with my neck and shoulders for a long time, probably due to working at a computer for long hours, and between his treatment, tips and "homework", my pain is relieved and not only am I no longer damaging my discs but I know that I am creating the best environment for them to heal!
My husband has had back pain for years that limited his activities. Again, Dr. Jack helped him find pain relief and increased his mobility. He started doing yard work again and has told me on more than one occasion, "Look at what I did ... and no pain!"

I've been a patient of chiropractic care since I was a newborn and, having only had four Chiropractors since, I can say that ongoing adjustments is the closest thing to having a mechanical engineer for your body.

There are two things I consider when evaluating the quality & level of care a Doctor of Chiropractic provides: Their ability to assess my body's condition before beginning treatment and recommendations for self care beyond the office visit. Having been a patient of Dr. Ricci's for over 7 years, his level of care is top notch. Sometimes my body requires just a slight
