Dr. Greg Seitz

Board certified in dermatology and laser surgery • Zoology and Psychology degrees from University of Wyoming • Doctor of Medicine from Oregon Health and Science University • Residency at University of Colorado • Fellow of American Academy of Dermatology, American Society for Dermatologic Surgery, Colorado Dermatology Society, American Medical Association and Wyoming Medical Association

Born and raised right here in Cheyenne, Dr. Greg Seitz is a proud alumni of the University of Wyoming. His love of the outdoors drew him to Oregon after graduation, where he earned his Doctor of Medicine and completed his residency and chief residency. During his time in these roles, Greg focused his training in the areas of medical, surgical, and cosmetic dermatology, as well as dermatopathology.

Prior to medical school, Greg served as an Emergency Medical Technician and ski patroller in Portland, OR, and completed several years of immunology research at Oregon Health and Sciences University. The results of his research were published in several scientific papers, as well as presented at both regional and national meetings.

Now back in his hometown, Greg and his wife are raising a family—two daughters, one son—and enjoying the spoils of Wyoming life by rock/mountain climbing, camping, hiking, and skiing as often as possible.
