Dr. Henry Oyharcabal, DC | San Francisco Auto Accident Injury San Francisco CA

From a very young age, Dr. Henry Oyharcabal was fortunate to have been groomed to focus on holistic, natural paths to health and wellness. His parents were skeptical when it came to automatically medicating any health concerns. They had both grown up in small farms in Southern France and were raised on natural organic foods.

As a native San Franciscan, Dr. Henry attended the University of San Francisco where he graduated pre-med. He then went on to earn his doctorate in Chiropractic at Life West University, graduating with honors. Dr. Henry also captained their soccer team to a division title. In Arizona, Dr. Henry mentored for two years with one of the largest practices in the country.

When Dr. Henry founded Atlas Chiropractic in 1992, his intentions were clear. He aimed to provide the best, all-natural chiropractic care in San Francisco to help restore his patients’ health and make a significant difference in all aspects of their well-being.

San Francisco Auto Accident Injury will help you achieve your wellness needs, improve your quality of life, and facilitate healing.

A prideful guest lecturer at the University of San Francisco, Dr. henry has set up a mentoring program for other physicians to learn the unique techniques for treating spinal disorders. His work with other chiropractors is appreciated by many as he instructs a class on Practice Management to other chiropractors seeking to serve more people.

Atlas Chiropractic has been certified by The Spine Research Institute of San Diego for case management of whiplash and other accident related disorders. We also take pride in being the San Francisco Pro Am Basketball League chiropractor, which showcases local pro and college players. Dr. Henry is often seen attending games with his sons Alex and Max, who both love the game.

Dr. Henry chose to study the Palmer Technique because it parallels his healing philosophy: Doctors don’t heal, yet assist in creating an environment where the body can heal itself. Even the subtlest of everyday stresses can misalign the spine and lead to back soreness, headaches, low energy, insomnia, lowered immune system, and chronic discomfort. The Palmer Technique helps restore the proper alignment and tension on the spinal cord. Many of his patients mention to him that they were afraid of chiropractors, but, once they got treatment, they learned how gentle and profound an adjustment could feel.


Here are some components that make getting care at Atlas Chiropractic so effective, long-lasting, and life changing:

  • Dr. Henry treats you as a unique individual. No judgments! No generic approach to your treatment protocol! Your path to health and wellness is as unique as you are and I respect that.

There is no separating them. If one is off, the others are inevitably compromised. It’s his mission to help you help restore and rejuvenate yourself to your optimal state of health.



Dr. Mike Shifrin

Medical Doctor & Chiropractor

Dr. Amir Ghanbarian| San Francisco Auto Accident Injury San Francisco CA

Dr. Mike Shifrin began having low back pain that radiated into his knee while he was a student at Penn State University. The low back pain would only happen while he was driving and he did not know what was causing it. He tried many different things to help with the pain, including medication, various creams, hot/cold patches, and placing pads behind his back while driving. Nothing seemed to work. Dr. Shifrin didn’t want to go see a doctor about this out of fear of them suggesting surgery or heavy medication. At the time, Dr. Shifrin’s mother was going to a chiropractor for headaches that she had been dealing with. She suggested that he go see a chiropractor. Although he had never been to a chiropractor and barely knew what they did, he wanted a solution for the pain. The chiropractor that helped Dr. Shifrin was very helpful in explaining what was going on with his back, and the chiropractor even explained what he wanted to do to help Dr. Shifrin’s pain.

Within three visits, Dr. Shifrin’s back and knee pain were gone and they never returned. The chiropractor that helped used to be a powerlifter and bodybuilder when he was younger, and he was able to relate to Dr. Shifrin with all the injuries he had sustained through working out. That’s when Dr. Shifrin saw himself in the chiropractor’s shoes. That’s when he began setting his sights on becoming a chiropractor.

After Dr. Shifrin graduated, he attended the New York Chiropractic College to obtain the necessary tools and education needed to help others in the same way he was helped.

“I believe all things happen for a reason and without the back pain I had, I would not be where I am this day.” —Dr. Mike Shirfrin
