Meet the Team

Dr. Sammy Hardin graduated in 1986 from Post High School in Post, Texas.  Two months later, he married his high school sweetheart, Pam. After working in a variety of industries, which included 15 years as a paramedic working on an ambulance, as well as in an emergency room, Dr. Sammy decided that his life's mission was to help people improve their lives by learning chiropractic care. 

He graduated from Parker College of Chiropractic in 2001. While in college, Dr. Sammy served as President of his class for the last year and a half. He also has served a term on the Alumni Board at Parker College of Chiropractic. In 2002, Dr. Sammy took over an existing practice, which is now known as H2 Wellness Solutions.  

Dr. Sammy utilizes at least 10 different adjusting techniques, which include: Diversified, Gonstead, Thompson, SOT, Activator, extremity adjusting, and Regenerative Wellness. He enjoys taking care of patients and treating people of all ages (from newborns just a few days old to people well into their 90s).  

He welcomes the opportunity to show you (and your family) how chiropractic and Regenerative Wellness can make a significant 

improvement in your health and well-being. 

Dr. Sammy specializes in Regenerative/Stem Cell Therapy, using the highest quality of Stem Cells on the market today.
