I really appreciated the nurses and doctors there. Everybody was very courteous and treated with a lot of respect. I thank them for everything they did for me and I will be back. The only problem I had was trying to find a place, but eventually I found them. And thank you all so much for everything you did for me. God bless you.

My doctors, all of them know me. They treat me. They treat me really, really good like I'm the only patient. They listen to me and they try to do everything in their power to help me out and I can call them. I can call them anytime that I have a question. but they're really, really, really good to me. I wouldn't go anywhere else.

Dr. Sivakumar was professional, yet approachable. She was patient with my lack of knowledge and explained so I could understand. Several times I asked the same question over out of nervousness. She always replied respectfully and explained again. I felt she genuinely cared about me and wanted to help. I felt we came together as a team. She advocated for me immediately. She didn't make any excuses. She had a "can do" attitude. I like her. She is very knowledgeable. She moved quickly and didn't skirt the truth. I feel we have a plan for my health. I am relieved to find a professional of her high caliber.

All things were handled and presented to me in a professional manner. I was presented with cards with pertinent information in case I thought of something that I needed clarification on once I left the office.
