Meet Diana

I have been practicing medicine for 6 years, and I currently serve as the Lead Advanced Practitioner with Mercy Health Physicians. My clinical interest is in family practice with an emphasis on chronic disease management and prevention. In 2018, I received the Excellence in Medicine award. I give back to the community by volunteering in various church activities. Outside of my career, I enjoy crafts, baking and spending time with my family.
