Dr Buchanan is the Best! - Huntington, NY

I would highly recommend Dr Buchin for bariatric surgery. He is the best! He spends a lot of time with you in the office explaining everything and thoroughly reviews all blood work results with you.

57 Year Old Male 295 Lbs Down to 165 - Huntington, NY

Dr Buchin holds regular group support meetings for ore and post op patients to discuss the entire process. He and his staff are experts on the approval criteria and process with insurance requirements and thoroughly prepares his patients with what to expect at every step per and post procedure. I had surgery on a Wednesday and was back at my desk the following Monday. The only real restriction was not being able to fly for a few weeks after surgery. I would definitely recommend the procedure and Dr Buchins practice Long. Island Obesity

The Best Thing I Ever Did. Huntington, NY

Choosing the right bariatric surgeon was a very difficult decision until I met Dr Buchin. The professionalism, the bedside manner, the pre-op and post-op care among other outstanding interactions that I've experienced from Dr Buchin himself and his office stuff made this journey of mine the most comfortable one. Dr Buchin is a true professional and an amazing person. From my first interaction with him at the consultation appointment to the 6th month after the operation follow up, he has shown a great deal of interest in my progress and has being there for me for all of my questions and concerns. His office stuff is outstanding and will go above and beyond to help you dealing with insurance, coordinating appointments and supporting you with diet and appropriate recommendations to keep you motivated. Finally, if bariatric surgery is your treatment of choice then I highly recommend to you my doctor. Dr David Buchin.
