Meet the Doctors

  • Dr.
    Mary Brechtel

    Dr. Mary Brechtel came to Galveston in 1998 upon graduating from Texas Chiropractic College (TCC), where in addition to her regular studies she completed a spine surgery rotation at UTMB. During her stay in Galveston, she became endeared with Galveston County and its people and decided to open her first practice on Stewart Road (Malott Chiropractic - 6511 Stewart Rd. Suite 7). After 13 years of practice Dr. Brechtel had built her own custom-built clinic just a few block from her original location. This change of location precipitated the name change to HealthMatters Chiropractic. She chose this name because she wanted the name to reflected her mission statement-that your health matters to us.

    In the past, Dr. Brechtel has shared office space with Family Practice, Internal Medicine, and Podiatrist Specialists and approaches health as a balance of natural and western medicine perspectives. Dr. Brechtel is a Board Certified Clinical Nutritionist* and certified in Pediatric Chiropractic**.
