Erica Costello, PA-C
Erica is the newest member of our team, starting in 2022 with Rocky Mountain Family Medicine, but originated in Casper 20 years ago, transplanting from California. Erica has been a physician assistant since 2015 and completed her professional training at St. Francis University. She enjoys pretty much anything outdoors, year round; you may find her out with her family camping, fishing, hiking, or cross-country skiing. She is a board member and very active with the Wyoming Association of Physician Assistants.
At Rocky Mountain Family Medicine she spends most of her week caring for long term care patients at Shepherd of the Valley Nursing Facility to satisfy her interest in geriatrics, but also cares for her clinic patients through the office several days a week as well. She continues honing her medical skills with her pursuit of certification as a diabetes educator and she enjoys dabbling in Functional Medicine. Prior to her career in medicine she spent time working with the BLM studying the migratory path of birds and wind turbines. We are excited to have Erica’s vibrant personality and years of experience caring for patients as a part of our team and we hope you get to meet her. She is currently accepting new patients on a limited basis.
