Zoe Gordon, DO – bio coming soon!
Jun Kim, DO
Hello, my name is Jun Kim. I grew up in the Denver area and am really excited to continue my training here! Denver health’s mission and goal of providing high quality healthcare to any and all people regardless of socioeconomic status is what drew me to this program. Everyone starting from the faculty leadership to the social workers to the MAs and front staff are committed to improving the health of our community. I feel really lucky to a part of the founding/growth of our program. I feel my curriculum can really be tailored to what I want out of my future career due to our leadership being so willing/open to our input while still having the stability of being connected with University of Colorado and their resources. Outside of medicine I enjoy karaoke and board games! Very much addicted to fantasy football currently in 4 different leagues. I’m a huge anime fan and I also love reality dating shows!

Cameron Walker, MD
Born and raised in San Antonio, TX, Cameron got her bachelor’s degree in nutrition at Texas Tech University in 2020. She then completed medical school at the Long School of Medicine at UT Health San Antonio in 2025. Cameron is a single mom to an amazing 6 year old daughter, and her experiences as a young mother greatly influenced her desire to pursue a career in medicine to help provide socially high risk moms and babies the optimal comprehensive perinatal care they deserve. She found herself gravitating towards DCHSFMR because of the learning opportunities provided by the high volume of value-aligned prenatal care at the Montbello clinic and continuity of care with families before, during and after birth of the child. She plans to eventually pursue a high risk OB fellowship after residency with the goal of a career as a rural FMOB. When she’s not seeing patients, Cameron loves playing music (piano/guitar/singing — especially karaoke!), dancing/aerial arts, spending time with family and taking long walks at Cheesman Park with her dog, Maui.
