This was probably the worst doctors visit of my entire life. I don't have one good thing to say about this doctor. He was very abrasive, rude and abrupt. I barely got one word in. I took my elderly grandmother who does not speak English to Dr. Greenbaum's office and he wouldn't give me the opportunity to translate what he was saying to my grandmother without telling me to stop talking. It was a terrible experience from start to finish and I highly suggest you stay clear of this allergist.

When I disagreed with his diagnosis, he told me “well that’s because you’re a liberal.” When I asked him what he meant by that, he pointed at my hair (I have the sides of my head shaved in a bit of a Mohawk), and said “we’ll you have that typical snowflake hairstyle.” Do Not See This Doctor!

Dr Greenbaum has lots of knowledge and experience if he would only take his time to explain to you why you need so much medicine and tell you what you have and if he would Believe in Biologics it would help people with Severe asthma and AERD a lot more with QOL Dr Greenbaum never learned how to spea To people probably to understand maybe why they are asthmatic

I have seen Dr. Greenbaum three times and have always found him to be friendly. Go in with a smile instead of thinking of the negative reviews posted here. He is very knowledgeable and easy to talk to. I would highly recommend Dr. Greenbaum.

Dr Greenbaum should retire. He did not take any medical history, did not take notes, there was no evidence of a computer or medical record. I was seen in his ‘office’ where I was seated in an old chair across from his desk, which was messy, and dirty. The test vials he placed on my arm were in an open unsanitary tray. I did not see any evidence of a clinical exam room, or a nurse in his practice. He was rambling and not making much sense. His clinical advice to me was ludicrous, suggesting I fill myself full of steroids and see how I react to a life threatening allergy. He even handed me a prescription with 30 refills ! Needless to say, not going to fill it, or go back. this man could really do some harm. Do not waste your time. October 2023

I have seen Dr Greenbaum twice in the last three weeks about my allergies.

Those of you making remarks about Dr Greenbaum's age are practising the worst type of ageism. You are judging him by his age and devaluing him based on the colour of his hair. He is a wealth of knowledge and knows far more, and has much more experience, than the younger allergist you were expecting to meet.

I don't understand all these negative reviews. I did not find Dr Greenbaum to be rude or dismissive at all. He has a "method" and needs to extract particular information from you in order to make an assessment. Those of you alleging that his style of testing is unhygienic and unsanitary, that was definitely not the experience I had. He even washed his hands between testing me for each of the fresh fruits I brought in.

Dr Greenbaum has a great sense of humour, is easy to talk with, and gave me time to ask questions. He seemed to have a great rapport with other staff members that he conversed with.

I highly recommend Dr Greenbaum. In my opinion, he leaves no stone unturned.

I learned so much from Dr Greenbaum and loved his bowties.

The worst doctor I have ever dealt with. I had to wait 3 months to get in to see him and he didn't even have the correct allergy test for me to take (yeast). He just blew it off and said it probably wasn't needed.

He then would ask questions and then cut me off very rudely. The third time he did this I called him on it as I was shocked and very angry that he was speaking to me in that manner.

Finally, he gave me a pre-printed sheet with information about heart burn and indigestion and started talking about that! I laughed and I asked him then if he even knew why I had come in to see him. He actually said that he hadn't seen very many people with an allergy to yeast, but welcomed me to come back in and eat something with yeast in it in front of him so that he could see what happened!

This guy needs to retire. I'm sure he once was a good doctor but no longer.

Do not have him treat you. My doctor who referred him to me was completely shocked and will not refer anybody to him again.

First time seeing the Doctor, found him to be very personable and knowledgeable. Office staff is great. No wait time to see him.

This was by far the worst experience I’ve ever had with any type of doctor. I’m not sure how he’s still practicing. He speaks at you, shushes you after asking a question and diminishes anything you have to say. He kept pointing at my boyfriend and I, saying shush. He discredited any previous testing I’ve had as well as my personal experiences. I was so uncomfortable being told how to feel and think that I decided it best to leave. I would run the other way if you’re referred to him.

The staff rating is a one star as I was only seen by him. I’m sure anyone else in the hospital would have been far better to deal with.

Terrible experience!

I have seen him twice and each time I found him rude, condescending, doesn't listen to you, talks over you, belittles you and many other non professional attitudes. I would not take my animals to him. Where did he get his degrees??? Out of a cracker jack box. I highly discourage anyone thinking of seeing him for their medical concerns.
