Why did you choose a career in endocrinology?

I fell in love with endocrinology when I did a rotation in it at Mizzou. Its science is sensible, and it has an impact on patients' daily quality of life. 

 

What do you enjoy most about being a physician?

I enjoy time with people, getting to know their stories and, of course, helping them do better. 

 

What do you like to do in your free time?

When I'm not in the office, I enjoy reading, exercising and taking photographs.

 

What is something that you want patients to know about you?

As a physician, I’m your friend. Together, we can improve your health and sense of well-being.
