What a wonderful doctor! Having a breast issue is never fun, but Dr. Memsic and the staff at the Bedford Breast Center were all so kind and efficient that it made for actually a positive experience. Dr. Memsic has a wonderful bedside manner-she’s very down-to-earth yet very caring. She listens and explains everything. The center itself is very comfortable—not at all cold and sterile. I HIGHLY recommend Dr. Memsic and the Breast Center !

I saw Dr. Memsic to address two small bumps, one on my arm and one on my leg, that were there due to muscle defects. She told me she could repair them using non-absorbable mesh. Shortly after surgery with her on March 3, 2015, I noticed that I could see and feel the mesh under my skin, particularly my arm. It looked horrible and felt even worse. A plastic surgeon had to remove the mesh. With respect to my arm, the CA Medical Board confirmed that Dr. Memsic deviated from the standard of care.

Dr. Memsic is one of our best surgeon. She is intelligent, expertise and caring. Every morning before 7:00 a.m. she was next to my bed during my surgery. She is indeed an angel. Love her so much. We are very lucky to have her.
