Daniel P O'Hair, MD

About

Dr. Daniel O’Hair joined Boulder Heart as Cardiovascular Surgery Program Chair in 2019. With a unique combination of skills and more than 20 years of experience, Dr. O’Hair works effectively in both the operating room and the cardiac catheterization lab. This allows him to advise patients from a perspective that can be matched by few physicians. At Boulder Heart, Dr. O’Hair performs a range of cardiovascular surgeries, including complex open-heart surgery and robotic-assisted mitral valve repair.

Dr. O’Hair is one of the nation’s leading experts in robotic-assisted mitral valve repair, and Colorado’s most experienced surgeon with this minimally invasive procedure performed with the da Vinci® Xi™ Surgical System. Dr. O’Hair also has been selected as a global proctor for transcatheter aortic valve replacement (TAVR), meaning he teaches other cardiologists to perform this innovative procedure.

Prior to joining Boulder Community Health, Dr. O’Hair successfully created one of the largest, high-performing heart valve programs in the United States and was active in clinical trials. He served as a medical community leader in Wisconsin for two decades, performing the first robotic-assisted mitral valve repair, TAVR, and mitral valve replacement (TMVR) procedures in the state.

Dr. O’Hair received his medical degree from Medical College of Wisconsin, where he also completed his residency and a research fellowship in general surgery. He went on to complete an additional fellowship in transplantation as well as a residency in cardiothoracic surgery at Columbia University College of Physicians and Surgeons.

    She has an uncanny ability to phrase what's going on with the situation, surgery, heart trauma in terms a "lay person" can understand. Highly respect her - her concern is top notch & TRUE to her word.

    I did not feel convinced that he had thoroughly read chart or reviewed imaging. Did not do a great job of explaining procedure, or using models or diagrams. Did not refer me to video, on web site.
