At the heart of concierge practice, is my commitment to providing the highest quality medical care to my patients. I can provide convenient, proactive, and exceptionally personalized care to each patient by keeping my practice small.

 About My Concierge Practice

Along with continuing my cardiology subspecialty, I also provide primary care to patients as an Internist. This combination allows me to take a holistic approach to patient care addressing not only specific health conditions but also promoting overall well-being. With my comprehensive knowledge and skills, patients can trust in me to provide personalized and proactive care, reducing the risk of potential cardiovascular problems and promoting a healthier lifestyle overall.

“I have always committed myself to putting patient care first. I always want my patients to leave whatever interaction they have with me-whether in the office, on the phone or even by text to come away sensing that I understand and respect them. At the same time, I try to always treat my staff and my colleagues with respect and to work as a team. I strive to create a caring and secure environment for my patients at all times.”
