Reviews By Our Satisfied Patients

    Prior to chiropractic care I had really bad back pain and neck pain. My experience with chiropractic care has been really good. I do not have as much back pain nor neck pain. It has really worked! It has continued to work really well and I am going on my second year of care.

    K. Robertson

    Since I’ve started with chiropractic care I have not had any headaches. The last headache that I had was the day of my accident. My experience so far with my chiropractic care has been amazing. Everyone is friendly and they actually love what they do. So far, my life is going well since I started receiving chiropractic care.

    S. Johns

    I was having trouble walking because my back was hurting and I had pain in my legs. After my second visit, I could tell an improvement in my walking and the pain in my back was improving. I can now walk a mile and there is little to no pain. I walk 3 or 4 times a week now!

    P. Hooker

    My family has had great experiences with Colleton Chiropractic! We’ve received treatment for work injuries, spine curvatures and as of this week, a not so wise jump out of a treehouse! From the ladies up front to all 3 doctors, they are caring and competent. Highly recommend!!

    Ellen W.

    Lots of good knowledge about things that I was totally unaware. Looking forward to getting my body back in good health. Wonderful staff!

    Scott D.

    I ride horses and have hip and back pain because they sometimes ride me! I was concerned I was going to get to the point where I couldn't ride anymore. After a couple of months of seeing Dr. Gallagher I feel soooo much better. I'm looking forward to many more trail rides! Dr. Gallagher is so upbeat and positve you can't help but feel better after seeing him! Everyone in the office is great! Very nice, professional, and accomodating.
