1. “Why Pathology”  The challenge involved in unraveling the mysteries of the human body is what attracted me to a career in medicine. As I progressed through my clerkships, the magnificent rewards of Pathology became quickly apparent to me. Pathology struck me as being very cerebral and pathologists are required to have knowledge of virtually every disease process that can affect any organ to diagnose them. This is what drove me to pursue pathology.
2. Why did you choose UT Health San Antonio? UT Health San Antonio was one among my first few interviews and I was quite nervous. However, the residents and faculty were quite easy to talk to and they instantly put me at ease. And that is one of best qualities about our program; the people are collegial, team players and want to do the best they can.
3. What do you like about living in San Antonio?  San Antonio is a friendly city with a rich heritage. Lower housing costs as well as no state income tax, warm weather, outdoor activities, and better traffic than in other larger cities are some of the perks of living in San Antonio. The airport is 10 minutes from the hospital which was important to me since I travel a lot to visit my family and friends.
