Today was my 1st visit to see Dr. Cantlon and he has such a great bedside manor, he’s gentle soft spoken, and easy on the eye lol. In all seriousness I really appreciate him and his staff taking such great care of me, and let me add no wait time which is very important to those of us who work. (5 Star Review on Healthgrades from D.M.)
Dr. Cantlon was terrific. He spent time with me, asking me questions, clarifying info and asking me if I understood. Got additional Xrays (tech was great too) which showed no break. So I was happy. Very happy.
Hopefully I don’t have to go back, but Greenwich ONS (Orthopaedic and Neurosurgery Specialists), the staff, and Dr. Cantlon (Hand and Upper Extremity Surgeon) were great. Highly recommended. (Five star review on Google)
Dr. Cantlon is very smart and is so nice. I would definitely go back and recommend. (Patient Survey)
Dr. Cantlon has been great. During our Greenwich Hospital ER visit for a pediatric broken thumb and the ONS follow-up visit, his efficiency, clarity, and bedside manner he had for me and my 11 year old was excellent! (Patient Survey)
