My goal is to establish open communication with patients so we can work together on taking ownership of their health and wellness.

I enjoy the meaningful relationships I have built and the inspiration I draw from patients every day in clinic. A healthy dialogue is an important part of the provider-patient relationship. Outside of work, I enjoy spending time with my family, writing, and staying active outdoors.

My mission is to treat the patient in front of me with compassion, dignity, and respect.

I believe that medical care needs to be tailored to the patient in front of me. I believe that taking the time to talk with the patient about their medical concerns is just as important as ordering tests and imaging. Taking the time to listen to the patient can go a long way to developing a respectful, trusted relationship, which can have a very positive outcome for patients. Outside of work I like rock climbing, hiking, and traveling.
