Walk-In Clinic

Family Nurse Practitioner

I am a board certified Nurse Practitioner specializing in family practice. I have been a nurse for 14 years, working my way up through my degrees from LPN, RN, BSN, and MSN in that time. I have worked with all ages of patients in a wide range of setting in my nursing career including, acute care, surgical care, long term care and occupational health care. I am also a Certified Health Coach and have done individual and community wellness coaching.
I have worked at the Shenandoah Medical Center for 8 years as a nurse in women's health, as a surgical nurse, as the Occupational Health nurse/wellness coach and now as a family practice provider in the Walk-in Clinic. I am so happy to continue my career here at SMC, and can't imagine a better facility, community or patients!
My hobbies include traveling and spending time with my husband (Kasey) and our children (Ethan, Aubrey, Ava, and Charly). I also enjoy fitness and exercise regularly and make it a huge part of my life.
