What led you to join this profession?
The versatility within the specialty. I knew from a young age that I wanted to be a doctor and always thought I would go into pediatrics. However as I progressed during my education, I began to fall in love with surgery. During my OB/GYN rotation in medical school, I quickly realized that this specialty not only had a surgical aspect but still allowed me to practice foundational/preventable medicine that I had been drawn to in pediatrics.

What do you enjoy most about your profession?
As an OB/GYN I love being able to make life-long relationships with patients and have the ability to support them through multiple stages of their life. We have the privilege to provide care for women for not only their reproductive health but also their general well-being and that is an honor to me.

I also enjoy reading, photography, running with Clark, and am an avid sports fan.
