Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Unprofessional
His response to an urgent call outside of office hours was so unprofessional and rude. Being a physician, I would expect his bedside manner to be kinder, more empathetic, and professional.

Bullet points b/c 1000 character limit: -patient for 5+ years -they could not fax or email records to my new doc, had to mail them, and I had to mail a letter to give permission and instructions -after receiving letter they still didn't send them. Took 1 month. -records were chicken scratch. Nothing digitized, no fax capabilities -After deciphering the records, my new doctor learned that for my allergy shot mixtures Dr. Weinstock had been mixing incompatible proteins - such as cockroach with tree pollens. This causes the plant proteins to break down and thus the immunotherapy's effectiveness is reduced. According to my new doctor, this has been common knowledge in the field for a long time. I wasted years and $$$ with this office. Always liked Dr. Weinstock b/c he was cheerful/nice to talk to. However as soon as I began getting treatment elsewhere, it became clear to me that the quality of care he provides is poor and that his office practices are woefully outdated. AVOID AT ALL COSTS

I have been a regular patient of Dr. Weinstock for almost 20 years. He has treated me for allergies, asthma and anaphylaxis. I am currently recovering from COVID 19, but still suffering from lingering respiratory issues. Even though I had not been to his office in approx. 16 months, I turned to Dr. Weinstock in my time of crisis, as he was the last allergist I had seen, and he is very familiar with my “pre-existing condition.” I was shocked at the response. Dr. Weinstock refused to speak with me, knowing I was on the phone and currently having breathing problems. His nurse/administrator, Mary Lou, must share his lack of compassion and professionalism, as she literally hung up the phone on me when I repeated my request for assistance. At a time when medical professionals impress us daily with their selflessness and generosity, I am completely horrified by Dr. Weinstock’s lack of moral character. Not to mention the total abandonment of his hippocratic oath during a global pandemic

Horrible Experience. Outdated office. Was given a run around when I tried to get copies of my records from him.

I had a wonderful experience at Dr. Weinstock's office yesterday. I called yesterday morning to schedule an appointment, and was told there was an availability later that same day(!). I came in, filled out the usual paperwork, and a few minutes later was shown to his office. Dr. Weinstock sat down, listened to all my concerns, and answered all my questions. He spent a lot of time with me and the appointment was not rushed at all. He went above and beyond, providing me with free samples of the medications I needed, and typed up (himself) detailed and clear instructions, making sure I understood the medication course. I walked out of the office with everything I needed! Overall, he's a very attentive and caring physician, and would strongly recommend him!

Doctor is unaware of what tests are covered within certain insurances. Sent me for tests and it ended up costing me $400. I have been to doctors for more than 20+ years and have never had a problem like this.

I have been a patient of Dr. Weinstock's for over 20 years. He is very knowledgeable and caring and always takes the time to answer my questions. I have recommended him to many allergy sufferers over the years and will continue to do so without hesitation.

Port Washington, NY – Nov 21, 2017

Would NOT recommend this doctor. I requested a refill for my nasal spray and he refused to give it. I was told that I had to be seen first. I had an appointment for the following week and a half, but was told to come in sooner. That was something I was unable to do as I work and have children. You would think I was asking for a controlled substance. I decided to find another allergist and when I did, I requested for my records to be sent to my new allergist...NIGHTMARE! He deserves ZERO stars!!

Dr Wienstock saved my life more then once and for that alone it deserves the 5 star review but he always goes way beyond any other doctor Iv ever had in calling me back when I need him and making time for me anytime I need an emergency visit he also is extremely friendly and was able to diagnose me after 6 other drs where not able to . Trust me he's your guy and now his new location is nice much nicer and more continent for me at 1000 northern blvd

The most disgusting dr I have ever met in my life. Would do anything to make a dollar. I'm 9 months pregnant on bed rest and he refuses to refill my prescription at the pharmacy bc he wants to make money on another visit from me. And even after explaining I'm on bed rest he still refuses to prescribe the medication I have been already taking for the past 2 years. Makes me sick to my stomach. Absolutely disgusting what he would do to make a dollar.
