Care Philosophy
I am dedicated to advance the care of Veteran patients with cardiovascular disease through clinical care and research. I serve as Chief of the Cardiology Section at the Rocky Mountain Regional VA Medical Center. My clinical interests are focused in preventive cardiology, lipids, and acute coronary care. More broadly, the 12 full-time academic faculty members in our Section provide a broad range of consultative and procedural cardiology care, spanning prevention, heart failure, coronary and peripheral arterial disease, electrophysiology, and structural heart disease. The Cardiology Section of the Rocky Mountain Regional VA Medical Center is an integral part of the Division of Cardiology of the University of Colorado Denver. Our Section is committed to advancing cardiovascular medicine through research and education. This includes basic research, clinical trials, health services research, and training of cardiology fellows.
