Cardiology | Cardiovascular Disease | HypertensionMy career goal is to make a personal difference to each and every one of my patients. I want them to feel respected and listened to, and in so doing, I hope to gain their trust. I take pride in utilizing the tools I have been trained to use to get to the heart of my patients’ complaints.
I am board certified in general cardiology and well trained in the use of 2-dimensional and 3-dimensional transthoracic and transesophageal echocardiography, nuclear imaging and stress testing. My areas of interest include preventive cardiology, hypertension and coronary artery disease amongst many others. I eagerly speak with patients about food as health and spend much of my time advising on healthy diets and lifestyle.
I enjoy my family time immensely and dedicate my free time to raising two beautiful daughters with my best friend and wife Teresa. We enjoy family vacations, family biking trips and relish in time at the beach. My recreational activities include running and biking as well as golf and tennis. My wife and I enjoy cooking, especially together.
