"I loved Dr. Mario! Not only was my surgery successful with a relatively easy recovery and minimal scaring, but my surgeon had awesome bedside manner, was extremely caring, and was always available for any follow up questions or care, both while in the hospital and after discharge. I highly recommend Dr. Mario to anyone that needs this type of surgery."

"I can not express what a wonderful doctor and human being Dr. Castillo-Sang is. He has always treated me with kindness and concern. Dr. Castillo-Sang really listened to me which I appreciated. My surgery went without any concerns. Dr. Castillo-Sang kept me in the loop explaining the why's and the how's. I highly recommend Dr. Castillo-Sang to anyone, which I already do."

"When first diagnosed in hospital, the Head of the Cardiac department recommended that surgery had a very high risk of death (based on being 80 years old) and the hospital would not allow an operation to repair or fix my mitral valve. After further consultation with my heart doctor, he recommended Dr. Castillo-Sang be consulted.

Dr. Castillo-Sang reviewed my records and agreed to perform the operation. He performed a non invasive open heart surgery and replaced my mitral valve. The surgery went well and was accomplished with out breaking any bones. The surgery was even accomplished without me needing to take any pain medicine. Dr. Castillo-Sang closely followed my recovery from surgery and kept me fully informed as to my progress and what I needed to do after release from the hospital. In addition, he is a really nice and caring person. He made me feel secure during the entire process.

Dr. Castillo-Sang is a gifted and caring surgeon who is constantly trying to improve the methods and techniques to lower the risk of surgery and also to make the operation less intrusive on the patients body.

What a great Doctor and Surgeon. I highly, highly recommend contacting Dr. Mario Castillo-Sang if you ever need the replacement of your mitral valve."
