I’ve been coming to Quantum Therapy for about two years and I must say everyone feels like family. Kenya and Marylene are always so welcoming and kind. Dr Manadan and Dr. O are so attentive. I recommended this place to so many of my friends. I look forward to coming because I leave feeling physically better and mentally. They’re awesome people please visit.
A PHENOMENAL PLACE!! I really love and always look forward to coming here for my treatment. I am always met with a smile and treated with care and compassion. Not only that, but the PT STAFF/Acupuncturist/Chiropractor are brilliant. From the receptionist all the way to the doctors you know they all have your best interest and healing at heart.
