Patient Comments (8)
Baldwin, NY |
I visited Dr O. for possible carpal tunnel syndrome. I had an MRI and EMG. I found the staff to very courteous and helpful. DR O was very throrough and spent a long time explaining my results and options. He is a considerate man an excellent physician showing patience and kindness.
I also am shocked by the less than positive reviews. I am a nurse by profession so I am very familiar with doctors across many disciplines. My neurological problem has been difficult to diagnose so I was recently referred to Dr. O. Dr. O is honest, forthright, thorough and patient. My consultation time was unhurried and not rushed His explanation regarding my plan of care was clear, concise and informative. EMG test results were given to me at checkout. Level of satisfaction with Dr. O high.

Well versed, patient. Diagnosed a serious problem and followed up with phone calls before and after surgery to check my condition.

I'm reading these other reviews and I am utterly shocked. I had a completely different experience with Dr. Ostrovskiy. He performed an EMG test on me and he was a delight to converse with. He's quite well-versed. He is very prompt with the appointments I've been to. He's been thorough in his exams and even remembered my concerns from a previous visit. As for his staff, so far, I haven't had any negative experience. Any questions I had when I called were promptly answered.
in Queens |
I called his office twice and spoke two of his office staffs, one is Nane Falane. I explained to her that I am an individual whose life is affected with limb girdle muscular dystrophy type 2b currently in need of a neurologist that has é experience in muscular dystrophy rather than a neurologist who specializes in the brain. I was told the Dr said he will not pick up my call because his policy is to come for a visit first. Basically he sees money before patient care. Nor a Dr at heart.
Brooklyn, NY |
Very dismissively. Passive aggressive. Just wanted to feed me pills and not listen to my concerns.
in New York, NY |
I was sent to Dr. Ostrovskiy to have a deep skin biopsy to check for neuropathy. He was condescending and disparaging throughout his high speed interaction with me, even making fun of me because I DARED use the word allodynia. He then engaged in a cruel refusal to share the results with me. I immediately surmised that the results were bad (they were) and would likely result in a life style change (they will). I was literally begging for the results for 5 days; I was refused. My rheum told me.
Queens Village, NY |
uncaring physician, communicating with his office is a tragedy.
