h2-269Dr. Sammy Hardin

Dr. Sammy Hardin graduated in 1986 from Post High in Lubbock, Texas.  Two months later, he married his high school sweetheart, Pam, in August.

After working in oil fields, retail stores, fast food, vegetable oil mills and spending 15 years as a paramedic working on an ambulance, as well as in an emergency room, Dr. Sammy decided to go to chiropractic school.

He graduated from Parker College of Chiropractic in 2001. 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.

Dr. Sammy took over an existing practice, and it is now known as H2 Chiropractic.  Dr. Hardin specializes in at least 10 different adjusting techniques including:  Diversified, Gonstead, Thompson, Sot, Activator, extremity adjusting and acupuncture.

He enjoys his patients and treating people of all ages (from newborns just a few days old to people well into their 90's).  He would welcome the opportunity to show you (and your family) how chiropractic care can make a significant improvement in your health and well-being.

"Before I came to see Dr. Sammy I could hardly bend, and now that I have been to Dr. Sammy I can bend over, I can touch my toes. He has definitely improved my quality of life. I owe so much to him. He will definitely change your life."

Brenda Davis

"I came to him to get help with my allergies. At first I was a little skeptical because you think how can a chiropracter help with allergies, right? He has these little wands that give me pressure where my sinuses are. He gives me electronic acupuncture. It really really helps keep my sinuses clear and I use to have to take allergy medicine every single day; and in the springtime more than once a day, and now I have probably taken three all year. He’s really helped me tremendously."

Carol Short

"I came to see Dr. Sammy because I had a significant difficulty with one of my shoulders. It was a very painless process, it worked very quickly. We were done in four to five minutes each time and within a very short period of time—two or three weeks—in my particular case, I started to see significant improvements in mobility and so it’s been a great experience for me."

Ed Balli

"Two days ago I fell and hurt my right shoulder and I literally couldn’t use my arm, I came to Sammy yesterday and then I came back again today and I can actually use my arm now. Thank you Dr. Sammy."

Nancy Trice

"I was in an accident in November and started chiropractic care because of excessive pain in my back and neck.  I have had back pain off and on  since I was a teenager due to Scoliosis, an abnormal lateral curvature of the spine and I would take the pain killer Advil as needed.  After several visits, I am pain free right now.  I can now continue working out at the gym 4 days a week and maintain a better quality of life and I owe it all to Dr. Sammy Hardin."

Jeff Postell

"I own a dog grooming shop and groom full time.  This involves a lot of lifting.  I also have horses that I like to work and have fun with.  Both of these activities requires a lot of arm and shoulder strain.  I have frequently, for the last 25 years, pulled a muscle in my lower back.  Even though I could barely lift my left arm because of the pain I had for 5 months, it was ultimately the pull in my lower back that brought me to see Dr. Hardin in March.  Up until this time it was a chore to just put my horses in their stalls to feed them let alone do anything fun with them.  After a couple of treatments my back was a lot better.  just a couple of months later, one day I realized my arm wasn’t hurting either!  Now I feel like going out in the barn to play with my horses again.  Thanks to you, Dr. Hardin."
