Dr. Henry Oyharcabal, DC

From a very young age, I was fortunate to have been groomed to focus on holistic, natural paths to health and wellness. My parents was 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 wholesome foods.

As a native San Franciscan, I attended University of San Francisco where I graduated in pre-med. I then went on to earn my doctorate in Chiropractic at Life West University graduating with honors. I captained our soccer team to a division title. I mentored in Arizona for 2 years with one of the largest practices in the country.

When I founded Atlas Chiropractic in 1992, my intentions were clear: to provide the best, all-natural chiropractic care in San Francisco to help restore my patient’s health and make a significant difference in all aspect of their well-being.

Atlas Chiropractic will help you achieve your wellness needs, improve your quality of life, and facilitate healing.


I am a guest lecturer at the University of San Francisco and have set up a mentoring program for other physician’s to learn our unique technique for treating spinal disorders. I also teach practice management to other chiropractors seeking to serve more people. Our office 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. I’m often seen attending games with my sons Alex and Max, both who love the game.

I chose to study the Palmer Technique because it parallels my 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 mis-align the spine, and lead to back soreness, headaches, low energy, insomnia, a lowered immune system and chronic discomfort. The Palmer technique helps help restore the proper alignment and tension on the spine and spinal cord. Many patients mention to me that they were afraid of chiropractors but once they get treatment they will see how gentle yet profound it could be.


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

  • I treat 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.
  • You learn that that the innate intelligence that controls and coordinates all function, healing, and growth of the body travels primarily through the nervous system, and that your body does have the ability to heal.
  • You come to understand how comprehensive and valuable the chiropractic adjustment is, whether you’re currently in good health or poor health.
  • I integrate your care into a realistic, manageable and effective schedule. I’m here to fully support your goals and make living pain-free with full health a possibility and a reality.
  • Without a doubt, optimum health begins with a healthy spine, yet that’s just the starting point, and my treatment focus also includes addressing your nutrition and mental well-being. There is no separating them; if one is off, the others are inevitably compromised. It’s my mission to help you help restore and rejuvenate yourself to your optimal state of health.
