Shelly Prather, MSN, APRN, FNP-C

Family Nurse Practitioner

Shelly completed her master’s degree in leadership and management in Nursing at Walden University with a post master’s at Gonzaga and Graceland University. She has always loved learning and is proud to have made honors, becoming a member of Sigma Theta Tau International Honor Society.

Shelly has a love for rural health care and has worked at outreach places with diverse populations in areas such as Burns, Prineville, and Madras Oregon. This has given her an opportunity to work in every area of a hospital, including supervisor. Shelly has a strong background allowing her to specialize in critical and intensive care for over 30 years. She has worked with diverse populations and ethnic backgrounds including all age populations, ethnic backgrounds, and cultures. Shelly’s specialties include emergency care, cardiac care, cardiac rhythm diagnostics, pulmonary emergencies and intensive care, surgical specialties, burn intensive care, labor and delivery with postpartum care of mothers and infants. 

She has enjoyed working at rural care facilities but also enjoys travel, which extended into the big city. This is where she was able to work in extensive travel nursing, which allowed her to gain experience at some of the largest hospitals in the United States, including Sharps and Scripts hospitals. While Shelly was at Sharps hospital, she was able to collaborate in the development of a Rapid Response Program designed to identify patients who were declining rapidly, calling a medical team to the bedside to intervene prior to the patient experiencing a catastrophic event and needing a code called. The program was a huge success and was brought to Oregon upon her return to the state where it was also implemented at Asante Healthcare systems in Grants Pass, eventually to be used at several hospitals across Oregon. 

Shelly’s hobbies include helping those who need it,  horseback riding, traveling anywhere warm with water, swimming, fishing, boating, animals, crafts, history, dancing, and music concerts, especially delta blues.

Shelly looks forward to being able to develop programs in Coos County, helping to develop programs needed. She hopes to be able to keep learning using the skills she acquired for the use and development in our community.
