Dr. Robert “Andy” Dunn

MD, MS, MHA,  CO-OWNER

Andy is originally from Denver, Colorado, but now considers himself a permanent resident of Wyoming since 2009, with no plans to uproot from this wonderful state.   He had an interesting path to medicine, with two graduate degrees and a stint in the minor league baseball system prior to applying for medical school.  He has worked in both the inpatient and outpatient settings in Casper since 2009. Throughout his time, he has helped direct, and work, the inpatient, outpatient, and community response to COVID-19 for two years.  He was Chief of Staff at Wyoming Medical Center from 2019 through 2021, Chief of Primary Care at Wyoming Health Medical Group from 2015 through 2022, and has received a numerous amount of awards, some which include the Outstanding Physician Service Award by the Natrona County Medical Society, the 2021 College National Finals Rodeo Hometown Hero Award, the Casper Police Department Community Partner Award 2021, and Physician of the Year for Wyoming Medical Center in 2013. Motivated by the call to help everyone no matter the circumstance or issue, Dr. Dunn finds inspiration from the Norman Rockwell painting ‘Doctor and The Doll’ which depicts a doctor listening to a young child’s doll to ease the child’s “white coat syndrome”.  The painting truly depicts a physician's responsibility to treat the mind, body and spirit of all patients.  

Sarah Peak

MSN, APRN, FNP-C,  CO-OWNER

Sarah grew up in Chadron, Nebraska and knew from a very young age that nursing was her calling. She began her journey through nursing in 2004 by becoming a Certified Nursing Assistant. In 2011 she became a Licensed Practical Nurse. She went on to become a Registered Nurse in 2012, which she worked as for 11 years before becoming a Family Nurse Practitioner in 2023. Sarah has worked in both the inpatient and outpatient settings in Casper since calling this community home in 2014. She helped work and direct the outpatient testing sites and vaccination clinic for COVID-19 for nearly two years. Taking a compassionate, patient-centered, and meaningful approach to healthcare, Sarah is excited to give our community an option for high quality care without having to deal with the hassles of out-of-state, large corporations. In Sarah's free time, she enjoys spending time with her children, Rowyn, Remi, and Ryder, and supporting them in their events, beating Dr. Dunn in Monopoly (or anything competitive), and going on trips or last minute adventures.
