What People Say About Dr. Alexander Losev, MD
RecentHighestLowestMost Helpful
I have been going to Dr. Losev for many years. I have found him to be always very pleasant and approachable. He’s an excellent doctor. The technicians are very professional and patient. My beef is not with him. Today, June 17th, after my visit I went to the rest room; I opened the door, and had to rush back out by its sight and odor. I know it didn’t get that way by itself. I went back to the desk to ask the receptionist if this was the only facility available, she and another staff person replied in chorus that it was, as I looked at another bathroom, which I presumed was for the staff. I told them the other one was filthy, but I was ignored. I am 80 + years, and I did not walk in from the street. I am a long established patient. This was the first time I had ever attempted to use their restroom. I was really hurt by the nonchalance displayed by the staff. I was an hour’s ride from my home. I think the receptionist was unfeeling.

I look forward to my visits to his office. Staff is wonderful, helpful and always welcoming. Responsive to your needs. Dr. Losev, the finest physician I have ever encountered. His diligence regarding follow up of my illness has exceeded extraordinary. He has become a trusted alliance in my care. As an RN, I trust him with my life. I cannot say enough about his demeanor, his ability to take the time to explain things thoroughly and treat me as an individual that he cares about.

Dr. Losev was just trying to milk insurance dollars at my own expense. He is rude, and abnoxious and all he wants is insurance money. He uses scare tactics to keep you coming back for more tests. Never mind I was in his office for 3 hours since he crams so many patients in at the same time.Run away from this doctor!

Dr. Losev from NYU was highly professional, provided a very thorough examination, patiently discussed all options and later on was promptly returning calls when I was leaving him messages.
