My Practice

My patients are at the centre of everything I do at work. Your long-term health is my top priority, no matter what brought you here: heart palpitations, chest pain, vein disease, shortness of breath, or even just to get a second opinion.

I will take the time to talk to you about your health and make sure all of your questions are answered. At the end of every in-person or online visit, you will be asked if you have any further questions, and I will leave no question unanswered. My style is personal, and you are not just a number to me; you are the reason I come to work every day.
