Biography
As an interventional cardiologist, I specialize in complex coronary artery disease, valve disorders and chronic total occlusions of coronaries. I believe that medical care should be a team effort among the physician, medical staff, family and most importantly, the patient. I strive to provide individualized care that’s tailored specifically to my patients’ needs and do my best to simplify complex problems so they can make informed decisions about treatment plans. I’m motivated to positively influence the health and lives of others.
In my free time, I enjoy spending time with my family and traveling.
