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.

I have recommended Diana to a lot of family and friends.

Diana is the Best!! Very attentive and thorough!
March 2022
The best doctor I've ever encountered. She's SO helpful in every way possible and actually cares about her patients.

I have already recommended Miss Kellar to many others. She listens to concerns, she is comforting and empathetic, she addresses your concerns and makes you feel heard. She remembers that things that may be obvious to medical professionals are not to most of us, and concerns that may seem unwarranted are still concerning. She doesn't make me feel like a hypochondriac or nuisance just because I'm asking questions or just trying to educate myself.
