General Information
Gender: Male
Language: English
Clinical Interest for Patients: I would describe myself as a general cardiologist. I am comfortable treating a wide range of heart problems, including but not limited to: coronary artery disease, heart failure, cardiomyopathy, atrial fibrillation, arrhythmias, valvular heart disease, hypertension, high cholesterol, and adult congenital disease. If a patients medical issue requires the additional expertise of a sub specialist in the field of cardiology, such as electrophysiology, transplant, stenting, structural heart disease, etc., I can refer you to one of my partners at University of Colorado Hospital at Anschutz Medical Campus.
Care Philosophy: I want my patients to understand their medical issues and the treatment options, including lifestyle changes, necessary to control or cure them. I try to develop a treatment plan based on medical evidence, common sense, and compassion.
Personal Interests: I enjoy getting up to the mountains for skiing in the winter and hiking in the summer. I like to exercise and try to do some every day, and I still play in the occasional rugby game. My other interests include cooking, photography, reading mysteries, traveling, and learning the guitar.
