About me

When I was younger, my mom needed treatment for rheumatoid arthritis. That experience influenced me to go into medicine, because I wanted to be like her doctors: to help people get better. It also highlighted that medicine affects more than patients themselves. It affects their families, too.

I’ve trained in a variety of medical fields, including Internal Medicine, Family Medicine and Oncology (Cancer care). Before I went to medical school, I earned a PhD in Chemistry. Today I’m proud to be a Primary Care Doctor at CliniSanitas medical centers.

Our doctors and staff are always eager to help patients and their families. At the end of the day, when I take off my lab coat and go home, it’s satisfying to know I helped my patients and families feel better.

I also have an artistic side: One of my favorite hobbies is drawing and sketching—especially faces. The one person I like to sketch most? My wife.
