MaryKate was an RN for 10 years prior to obtaining her Family Nurse Practitioner certification and licensure in Pennsylvania. Her goal has always been to work in behavioral health and will be pursuing board certification in psychiatry in the near future. MaryKate joined the U.S. Navy Reserve in 2014 and has been a commissioned officer in the Nurse Corps for the last 8 years. She was called to Active Duty early in 2020 for 6 months and thankfully returned home safely to her 5-year-old son later that year. MaryKate’s professional relationship with the Retreat started in 2017 when she was working as a nursing instructor in Lancaster CTC’s LPN program. Her students came back each week from their shadowing experiences at the Retreat full of excitement and inspiration. Many of her prior students now work at the Retreat as experienced professionals and she is very proud of them. MaryKate started working full-time at the Retreat as a Nurse Practitioner and her passion for nursing mentorship, education, and behavioral health lead her to pursue the Director of Nursing position in March 2022. MaryKate feels honored to work alongside such incredible nurses and see firsthand the life-changing work they do for our patients every day.
