The doctor is very thorough and very considerate. My husband and I are very satisfied with our care. We both feel that Dr. Sadasivan takes much more time with us than our previous provider, who we had for many years. We have nothing but praise for this office and staff.

My visit was not completely over with and it was my first visit ever with this doctor and I asked her before it was over if I could keep her as my doctor. That's hell great she was and how well she took care of me. I've only ever had one other doctor that did the same and that was a while ago and that Dr moved away. This doctor was fantastic, helpful and I found out more things about what was going on with me with my one visit with this doctor than I did in years with my old doctor. Thank you
