“After three years of searching, I finally found Dr. Felix — and truly, he is exceptional. If you’re struggling to choose a chiropractor, do yourself a favour and book an appointment with him. My husband and I have been seeing him for a few months now, and he has helped us tremendously in our recovery from chronic back and neck pain. His professionalism, kindness, and genuine care set him apart. Dr. Felix is not only highly skilled, but also respectful, attentive, and dedicated to his patients. We are incredibly grateful for the difference he has made in our lives.”Read moreShow less

“I agree with the other reviewers here. Felix definitely has magic hands.
My work involves standing all day under pressure and despite my own efforts to keep a good posture and do exercise, the strains of daily life end up taking their toll on my body. Felix is quick to identify my problem and treat the cause. In my case, he massages the problematic areas to loosen before adjusting. Within seconds after my adjustments, I could feel the tension in my neck and back muscles melting away like butter. My range of pain-free motion has greatly improved and the results are long lasting after a single session.
Not only is he competent in his craft, he's also a great listener. Makes you feel at ease. Just an all around great person. I'm grateful to have discovered Felix and will continue to be a loyal patient.”Read moreShow less

“Been seeing Felix for a while now. Hands down best Chiropractor I have seen in years.
Happy to have found him. I’m a circus artist and acrobat and work with my body for work.
I’m also a certified massage therapist so I’m comfortable with anatomy.
He knows the body, he cares about what’s going on, listens and then he will straight away be able to identify the issue and adjust the body so it can heal correctly.
Thanks Felix you’re the best 💪🏽💪🏽”Read moreShow less
