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 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.

A LONG TIME PATIENT in Deer Park – Sep 29, 2017

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.

I went to Dr. Allen's office for the first time on Friday. His office states they have walk in hours for sick appts, so I walked in Friday right before they were about to close. The front staff was so nice to me, saying no problem at all and squeezed me right in. I waited no more than 5 mins, Highly recommend.

I would not know given the fact that I see the PA he has in his office. What you need to know is that the office staff, especially the office manager, who works from Florida is grossly incompetent. Her refusal to provide referrals for patients has been well documented. She threatens to discharge patients when her competence is tested. I truly have no idea why these Doctor's would trust her to have any interactions with patients in any capacity.

The office staff is inadequate and frustrating to say the least. I have called several times to get referrals don't even have the decency to call back patients . They do not send referrals promptly, nor do they send scripts when asked to do so. YOU NEED A NEW STAFF!!!!!!

This whole experience with Dr Allen has been unbelievable. This is something I never do but I feel I have to this Time. I went to him as a new patent after looking at reviews on line. It took over to months to actually get results back from a physical. It started with my first visit that I thought was with him. No it MP then had to wait another month to see him then had to wait 5 more weeks to get my results from all the test he did. I am running out of space. Do not go to him it is a schame.
