Work History & Leadership:

I am originally from near Chicago and attended medical school at the University of Illinois, followed by a internal medicine and pediatric residency at Rush University Medical Center. After residency, I joined the US Public Health Service and relocated to Atlanta as a fellow in applied epidemiology with the Centers for Disease Control and Prevention’s Epidemic Intelligence Service, focusing on rotavirus vaccine effectiveness.

Once my fellowship was completed in 2010, I transferred to Arizona where I provided primary care, HIV care, and hospital-based medical services to patients on the Navajo Reservation at Tuba City Regional Health Care Corporation. In 2015, I moved to Flagstaff to work as an Internal Medicine and Pediatric Hospitalist with Northern Arizona Healthcare, where in addition to caring for hospitalized patients, I led Northern Arizona Healthcare’s provider response to the COVID pandemic in 2020 and 2021. I joined North Country HealthCare in 2022 as the Quality and Population Health Medical Officer and I also provide primary care to children and adults.

Fun fact: On my free time, I enjoy spending time outside with my kids, dogs, cat, goats and chickens. I also enjoy hiking trail running and gardening.
