OUR ONLINE REVIEWS
I have been a patient of Dr. DiSiena for over 30 years. The treatment I have received has progressed with the difficulties and challenges of growing older. Everyone in the office is pleasant and supportive and Dr. D is, as always, conscientious, thorough and an absolute delight.
My wife and I visited Dr. DiSiena for the first time for a few different ailments, and we were blown away by the experience. He is absolutely AWESOME—extremely smart, genuinely caring, and incredibly knowledgeable across so many areas. For the first time, we feel like we’re truly on the right path to wellness. He doesn’t just try to mask symptoms; he focuses on treating the root causes and helping you actually heal. We’re so grateful to have found him and couldn’t recommend him more highly! The staff was also very warm and welcoming. The clinic is beautiful as well. We have found our place.
I brought my son to Dr. Harbin after he started experiencing back and shoulder pain from playing football and lacrosse at a high level. From day one, Dr. Harbin impressed me with his professionalism, expertise, and genuine care for young athletes.
He took the time to understand not just the symptoms, but also the demands of my son's sports and schedule. The treatment plan was thoughtful and effective--targeted adjustments, stretching routines, and injury prevention advice. Within a few visits, my son was moving better, experiencing less pain, and performing at his best again.
What really stood out was how Dr. Harbin communicated with both me and my son, making sure he understood his body and felt empowered in his recovery. It's clear he has a passion for helping athletes stay healthy and strong.
Highly recommend to any parents with active kids--this kind of care is a game-changer!
Outstanding! The best Chyropractor in the country. I drive 2.5 hrs to see Dr DiSiena, he’s kind, cares about his patients, and extremely knowledgeable. I always go in feeling horrible and come out feeling like a new person. 10 out of 5 stars! ⭐️
Dr. DiSiena isn’t just a doctor—he’s a *medical maestro* in his field with next-level expertise that leaves you in awe. Your visit feels like VIP treatment, thanks to his expertise , knowledge and genuine, patient-focused care. The office Staff are an absolute perfection Warm, razor-sharp efficient, and so attentive it’s like they read minds. This isn’t your every day healthcare—it’s a doctor five-star experience.
Dr D’e office is amazing. First and foremost, vs your average medical office, the staff here seems to care. I really appreciate the holistic approach they take to fixing root causes. I was in the Bud’s Odessy program and had to halt it with the birth of my second daughter. I called the facility and they were very understanding and just went over my Organics acids test which seems to really have pinpointed some issues for me which has helped me finally pinpoint some things. Looking forward to the protocol they will put me on and couldn’t be happier with this group of people, their organization and what they stand for.
