Melissa Roop, Director

Melissa Roop, MD is a Family Practice physician currently working in Boise at Full Circle Health, a Federally Qualified Health Center. She enjoys working with underserved populations, and seeing their unique vulnerabilities to the health effects of climate change is part of what brings her to ICCH.  She grew up as a "Forest Service brat" where she learned the value of the land at a young age. She became interested in Climate Medicine after she completed residency training, a time when she felt her work in medicine was at a disconnect from her core value of caring for our planet.  She is currently focusing her energy in this space on provider education and decarbonization efforts in her health system. She hopes to soon work with her local community and later the state and region on climate resilience strategies.  Outside of work she enjoys gardening, running, rock climbing, knitting and cooking alongside her partner, son and two dogs.
