I was always skeptical of chiropractors. When it was recommended by my primary doctor after exhausting every other avenue for relief of an issue I saw an opportunity online to just come in and try it at 100% Chiropratic. Dr. Jasmine and Dr. Greg wants to help you reach your greatest health goals, feel better, and experience life to the fullest. So 6 months later I’m still using the program specifically for my issue. If you’re like me and question if it’s advantageous. Just sign up for the no commitment initial visit and I’m betting you’ll be pleasantly surprised.The staff and doctors genuinely care!

100% Chiropractic is hands down one of the best! It’s such a personable, family-friendly environment — you can truly feel the positivity the moment you walk in. The entire team is always smiling and welcoming, making every visit enjoyable. They also host super fun health and wellness events and activities that I’d strongly recommend to anyone to participate in. You can tell they genuinely care about their patients’ overall well-being, not just their adjustments. Highly recommend!

I appreciate Maddy & her partner up at the front desk. They always check me in, schedule my appointments, And they are so welcoming. As for my chiropractor, Zoe, I appreciate her adjusting me, making sure I like how I am being adjusted, and her knowledge is refreshing. I can definitely say I enjoy coming here especially when you all make it seamless.
