Dr. Curtis Martin

Dr. Curtis Martin, Concord Chiropractor

Dr. Curtis Martin was introduced to chiropractic at a young age. At the age of 6, Dr. Martin’s father injured his low back in an industrial accident. The medical doctor recommended surgery, but due to a surgical waiting list, he was forced to wait six weeks for the operation. In the meantime, his back pain was unbearable. While still on crutches, his dad hobbled into a chiropractor’s office. As he continued chiropractor care, his health improved. He no longer needed the surgery for which he was scheduled. Through the detection and correction of subluxation, his Dad was able to get the care he needed and regain his health. From that moment, Dr. Martin’s entire family became life-long users of chiropractic. This experience made such a difference in Dr. Martin’s life that he went to chiropractic school, graduating from Western States Chiropractic College in 1997.

For the past 15 years, Dr. Curtis Martin has been changing lives with chiropractic and has three offices located throughout the Bay Area specializing in corrective care and wellness care for both children and adults. Dr. Martin is committed to promoting the health and well-being of our community and making this world a better place through chiropractic care.

Dr. Curtis Martin specializes in:

  • Cervical and Lumbar Disc.
  • Gonstead, Diversified Adjusting, and Activator.
