Dr. Heather Prochnow

DVM

Dr. Heather Prochnow was born and raised in the Chicago suburbs until she went to college. She obtained her undergraduate degree in Biology and Spanish from Lawrence University in Appleton, Wisconsin and graduated from veterinary school at the University of Illinois in 2012.

After practicing for a few years in Illinois, she moved to northern Virginia and practiced there until early 2023. Following the pandemic, she and her partner Brian decided to move west for a better quality of life and access to all the outdoor Colorado fun! Her favorite aspect of working in a small animal general practice is forming bonds with owners and working closely with them throughout their pet’s life.

She’s also a fan of podcasts, true crime, dinosaurs, and spending time with Brian and their two black cats, Monster and Dexter.
