Matthew Nelson MD CMP1738Edit 2 1 Matthew Nelson, D.O.

Primary Care OB Fellow 

I was born & raised in New England, & now claim the West as my home. I studied cultural anthropology in Utah kindling an interest in how health & wellness is perceived across cultures, especially among the Navajo of the Southwest. Along the way I married my best friend & relocated for my graduate education at the University of New Mexico in medical anthropology. However, it was during this time that I became more interested in directly contributing to the health of traditionally marginalized and underserved populations. Medical school took our family to AT Still School of Medicine in Arizona where I entered a dual degree program that allowed me to earn a Masters in Public Health (MPH) along with my medical degree. We then moved to Western Colorado, where I completed my Family Medicine with an emphasis in obstetrics in Grand Junction. Now after 14 years of marriage and five little boys, we are excited to join the team in Denver and look forward to continued learning and service.
