Academic Title: Associate Professor

"My interest in Dermatology stemmed from my mother's diagnosis of melanoma, as well as my interest in our immune system. It was when I started caring for children with skin disorders, however, that I knew I had found my calling. Specializing in pediatric dermatology brings me so much joy: from a patient's smile when discussing Pokemon, Paw Patrol and superheroes with them, to improving a parent's understanding of their child's skin condition or advocating for the health and well-being of the children and families I am lucky enough to serve. I am so grateful to be entrusted by parents to care for their children, and to have the opportunity to do something that I love every day."

  • Biography

    Markus Boos, MD, PhD is an attending pediatric dermatologist at Seattle Children's Hospital and is an Associate Professor in the Department of Pediatrics at the University of Washington School of Medicine. He is also the Program Director of the Dermatology Residency Program at the University of Washington.

    Dr. Boos was raised in the suburbs of Detroit and received a BA in Biology and Economics from Kalamazoo College in Kalamazoo, MI. He subsequently joined the Medical Scientist Training Program at the University of Chicago, where he obtained his MD and a PhD degree in Immunology. He completed an internship in Pediatrics at the University of Chicago's Comer Children's Hospital before joining the Hospital of the University of Pennsylvania as a Dermatology resident. There he served as chief resident during his final year before completing a fellowship in Pediatric Dermatology at the Children's Hospital of Philadelphia.

    Dr. Boos enjoys caring for all children with skin disorders but has a special interest in LGBTQIA2S+ health, the effects of climate change (including wildfires) on the skin, and the cutaneous manifestations of Primary Immunodeficiency Disorders (PIDDs). When not seeing patients, you can find him teaching residents, giving talks and working to reduce healthcare disparities.

    As a gay father, Markus enjoys watching Survivor and playing Mario Kart with his twin boys. He also enjoys weightlifting, biking and swimming in Lake Washington. He cheers for the North Seattle Titans, the Hazel Wolf Wolfpack, the 'Hawks, M's, Detroit Red Wings and San Antonio Spurs.

    Dr. Boos, like all of Seattle Children's, values diversity and welcomes all patients and their families, regardless of race, ethnicity, religion, socioeconomic status, political affiliation, sex, gender identity or sexual orientation. Our clinic is a safe space where everyone is valued for who they are.
