What Our Patients Say

I can't say enough good things about Heathrow Chiropractic. If you're looking for a chiropractor that treats you more on a personal level than a number, I highly recommend you go to the best chiropractic doctors I have found in Central Florida. After one visit, I'm sure you'll agree with me. I want to thank everyone in the office for making me feel comfortable and helping to resolve my problem

My husband and I have been coming to Heathrow for about 5 years and my experiences have been nothing short of amazing. I can literally pick up the phone and they seem to ALWAYS have a way to fit me in that same day! I also most recently started bringing in my children and it has worked wonders. I would definitely, definitely, definitely recommend this place.

I highly recommend Heathrow Chiropractic to anyone and everyone! The front desk staff is AMAZING! They are thorough and make time to answer any questions you have without making you feel like an inconvenience. I'm always seen on time and asked how I'm doing. Everyone who works there has a great personality, and really cares about you. I'm so grateful to have them.
