In my 55 years of life I have never met a more incompetent doctor in my life. Treats her patients with no respect talks down to them. She should not being playing doctor when people are in need of health care. So run for your life it depends on it.

Dr. Ilona Sylvester is the best Dr. that I've ever had. And I've gone to a lot of Doctors. She is a very caring Dr. who will listen to you and help you in every way she can. She makes sure you understand things and has great bedside manners. And makes sure you have a follow up appointment after you've had a procedure done or a test done. She's helped me in so many ways where other Doctors have just giving up. I hope she is my Dr. forever.
