About Me
I am a board-certified cardiothoracic surgeon at Memorial Cardiac and Vascular Institute. I care for patients in need of coronary artery bypass grafting, heart valve repair/replacement, advanced mechanical support for heart failure, as well as transcatheter-based therapeutics including TAVR/MitraClip. I am trained on the latest transcatheter technologies, which can help treat heart conditions using minimally invasive techniques.
I grew up in a small town and initially wanted to become a pediatrician to help create a foundation of healthy living for children. As I was exposed to different areas of medicine, I was drawn towards surgery – I love the immediacy of it. Surgeons do not have to wait months or years for their interventions to make an impact. We see a problem and fix it. I’m excited by how rapidly our field of medicine continues to develop thanks to new, minimally invasive technologies.
Heart surgery can have a dramatic impact on someone’s life. Whether providing coronary artery bypass for patients experiencing a heart attack or alleviating heart failure symptoms by replacing an aortic valve, heart surgeons save lives. When working with patients, I try to both provide evidenced-based, life-saving surgery and also teach/coach my patients through their experience.
I am involved in clinical research exploring the outcomes of cardiac surgery on high-risk populations and teaching physicians/allied health professions at many different levels of practice. Before joining Memorial, I was a cardiothoracic surgeon at Holy Cross Hospital in Fort Lauderdale. I also served as an adjunct assistant professor of surgery for the University of Miami.

Research
Cardiothoracic surgery is a rapidly evolving field. Outcomes research helps us explore the benefits and risks of new procedures while also improving the quality of care for patients. My research interests include regenerative medicine, sepsis, and surgical outcomes research. My surgical outcomes research focuses on unique, at-risk patient populations. HIV patients represent an at-risk patient population with little known regarding their cardiac surgery outcomes.
South Florida has one of the largest concentrations of patients living with human immunodeficiency virus (HIV) in the country. The prognosis and management HIV has vastly changed with the advent of antiretroviral therapy (ART), accounting for a 7-fold increase in life expectancy. However, HIV patients today live with a chronic illness and have a 4.5-fold excess risk of cardiovascular disease secondary to their ART medications. My recent research has focused on evaluating the outcomes for these patients for elective cardiac surgery.
