Stars testimonials

“Great chiropractors and staff! … Dr. Pettiet has been taking care of my bac (neck , shoulders, knees, ankles, hips… you get the idea) for about 6 years now, and very pleased with them. They take the time to really listen and address the root cause of any discomfort rather than simply adjusting you and sending you out the door.”

Angela F.

It was his passion for helping people and his personal experiences that led him to Chiropractic care. Dr. Pettiet began seeing a chiropractor at an early age, because his mother, a chronic headache sufferer, understood the value of chiropractic care. Over many years, Dr. Pettiet was treated for a multitude of sports injuries and a fairly severe motor vehicle accident that threatened his ability to continue to play baseball, a sport that he loved. He has been a firm believer in chiropractic treatment ever since.

Dr. Pettiet graduated from Texas Chiropractic College in 2005 with a Doctorate in Chiropractic and Bachelors in Human Biology and he has never looked back.

“Helping patients live healthy, active, pain-free lives is a daily blessing. I love that Chiropractic has allowed me to bring happiness to so many people”.

Dr. Pettiet and his wife have owned Tomball Chiropractic Spine and Rehab Center since 2006. His joyful attitude toward life and chiropractic care echoes off the walls of his office and Dr. Pettiet likes it that way. His lighthearted and genuine approach to patient care is something that his patient’s appreciate as much as the treatment he provides.

“Laughter is incredibly therapeutic, even for patients in pain. Although, undeniably, they find me much funnier once they are out of pain.”

His multidimensional approach to patient care allows him to treat a vast array of neuro-musculo-skeletal issues.

“We believe that problems, especially chronic problems, are often multi-layered and multi-faceted. Thus, we must approach these problems from a multi-dimensional perspective. Over the years, we have developed amazing relationships with medical doctors of many different specialties that take a like-minded approach to patient care. We understand that chiropractic treatment alone is valuable, but coordinated care with other doctors often allows for greater effectiveness and faster results, which our patients appreciate.”
