Mario Augusto Castillo-Sang,

On June 14, 2025 the nationally and world renowned not to mention extremely talented Dr. Mario Augusto Castillo-Sang performed triple bypass open heart surgery on my heart. I can tell you without hesitation this very talented man flawlessly performed that life saving surgery to perfection. Not only is Dr. Sang simply the very best in his field, but add to that his deep caring nurturing nature and total dedication conveyed to his patients is indeed unsurpassed by all others. He's been given a talent and gift from God, and he uses those talents and gifts to the fullest to insure a positive and wonderful outcome to his patients. If you're in need of heart related surgery, I totally recommend this outstanding heart surgeon to you. In closing, thank you so very much Dr. Sang.

Dr. Mario Castillo-Sang is truly an artist of a surgeon, a caring human being, and without a doubt one of God's angels on this earth. His skill, dedication, and compassion saved my wife's life through minimally invasive open-heart surgery. From the very first consultation to the moment she was safely out of surgery, Dr. Castillo-Sang showed not only incredible surgical expertise but also genuine care for her as a person. He explained every step, answered every question, and gave us complete confidence that she was in the best hands possible. It's rare to find someone who combines world-class skill with such humility, kindness, and faith-driven dedication to saving lives. Our family will forever be grateful to Dr. Castillo-Sang for the gift of more years together. -- Brandon & Tiara Harrison

Yes service was great once you get there and are waited on. But the communication between the patient and nurses setting up appointments are confusing and not all details are communicate Canceling an appointment is ok but there is no follow up with the scheduler that is checking on an open date. Still no appointments that I know of have been schedule. And this is about open heart surgery that they say is necessary to get before the surgery. I guess I need to call them back again Ok thank you

Dr. Castillo-Sang gave me the best doctor/patient experience of my life, during one of the most scary and difficult medical decisions of my life. Truly not enough adjectives to describe his knowledge, professionalism, bedside manner and most importantly, surgical skills! His entire team is truly, "Best in Class" from start to finish. How do you thank someone for adding years and quality of life to one's life other than to say, "Thank You!" from the bottom of my newly repaired and better than ever heart.

Dr. Mario Castillo-Sang was very thorough in answering all of our questions and concerns in preparation for my heart surgery. The pre-surgery consultation was not rushed in any way, and prepared us very well for what would take place during and after surgery. Even as I worked through a few post-surgery setbacks, Dr. Castillo-Sang has always been very attentive and available to help me through those bumps in the road, while at the same time, assuring me that the minor setbacks were often very normal. His follow up is amazing! His level of genuine concern and professionalism continues to be a tremendous source of encouragement to me and my family. And I consider myself truly blessed to have landed under his very capable care!
