he's been my primary for a few years now. he's really great. he likes to prevent things from happening before they happen so he'll mention options to get healthy before things get worse which is awesome. it's not always about medicine.

I just saw Dr. Allen after reading his reviews. Must say they are all accurate. A really caring , down to earth doctor spent an hour with me on my first visit. He is clearly extremely intelligent and competent.

I have been seeing Dr. Allen for several years and am very pleased with him and his staff, particularly his office manager Bridget. They are both empathetic and knowledgeable and provide outstanding service to the patients. I have relied on Bridget many times through the years, often requiring a referral or other important matter at the last minute. She always delivers with her caring manner and excellent attitude. Doctor and staff work together to make the patients experience here a great one.

I was referred to Dr. Allen after a move from Staten Island. He is the best most caring doctor. . He is very knowledgable and I trust his judgement implicitly. His office manager Bridget is excellent. She runs the office extremely well so wait times are never excessive. Bridget is a caring person who always puts patient's needs first. Several years ago I had a serious health issue and was waiting for the results of a blood test. She called me from her house at night to let me know all was ok.
