Dr. Sivakumar has been my primary doctor for a few years now. I have recently decided to find another doctor, only because the wait times are very extreme and I can not wait all day at a doctors appointment. The doctor himself is amazing and genuine, but not so much for the reception staff.

Dr. Sivakumar is a keeper. I was ready to give up on the medical profession but he restored my faith. I recommend this doctor to anyone who needs a really good and caring doctor and his staff is just as caring as she is.

This is one of the best doctors I've ever visited (and I'm 56 yrs old.) Not only does he listen, but he acts in a timely manner on what he hears.

Dr Sivakumar has bent over backwards to help my mother who is a very difficult case. I have had to deal with him alot as she has had to be in and out of the hospital, but I always know he will visit her and be constantly aware of her situation and her health problems.Office staff was very kind.
