Get To Know Me
Why should someone choose you to care for their health?
I am dedicated to providing up-to-date evidence-based medicine to all my patients. My patients can expect my undivided attention during each appointment while we create individualized treatment plans to meet their healthcare goals.
What is the most important thing your patients should expect from their professional relationship with you? What do you expect from them?
My patients can expect a genuine physician who listens to them and provides them with the best care possible. I expect my patients to have honest and open communication with me so that we can develop the best care plan tailored specifically for them.
How do you spend your valuable personal time when you’re not caring for patients?
When not caring for patients, I enjoy spending time traveling the world with my family and friends. As a dog lover, I also enjoy going on leisurely walks in the park and hiking with my corgi.
Why did you choose your specialty and what is its greatest reward?
I chose family medicine because I find it extremely rewarding to develop lifelong relationships with my patients from childhood to adulthood, helping them maintain their health to reach all of their goals.
