I am just getting started with 100% chiropractic, yet I am already impressed; I felt compelled to write a review with five stars all the way! The staff, including Miranda and Greg, are fantastic. The Team is well organized, friendly, and make it all easy to understand. The space is light, airy, clean. I highly recommend!

HANDS DOWN the best chiropractor in St. John's! Stop scrolling & book here - you'll thank me later. From the moment you walk in, you feel cared for. I'm an avid hiker & the decompression tables + massage significantly helped my lower back. They also have a cold laser for my sports related injuries & my knees have never felt better.

If you are looking for great patient care with results, look no more. Definitely the best team of Doctors. Thanks to Dr Jasmine, Dr Greg — I'm feeling so much better!
Michele Mazabras • Apr 1, 2026
I've been coming here for over a year now and they have helped me feel so much better. Recently I had some neck issues and they were great. Took me right away and have helped tremendously. I would highly recommend all 3 Drs.
