Master’s in Public Health: University of North Carolina, Chapel Hill
Residency: Internal Medicine, University of Virginia

I was born and raised just one county over in Clyde, so moving back to Western North Carolina was in a literal sense “coming home.” Primary care is my passion—being the first person patients come to, having the opportunity to advocate for them, and helping them navigate our complex medical system is challenging but so incredibly rewarding.

In the clinic, I see patients with medical students and residents and co-manage MAHEC’s Post-Acute COVID Clinic with an excellent team of nursing staff and with assistance from Behavioral Health, Peer Support, and Social Work. Through collaborative team efforts such as this, the process of getting patients the help they need is easy and efficient. Within the realm of doctoring, my interests lie in improving health disparities in rural communities and training future doctors to thrive in caring for underserved populations.

Dr. Mueller has been a primary care doctor since she finished residency in 1994. She trained as both an internist and pediatrician at the University of Cincinnati and Cincinnati Children’s Hospital Medical Center. She has a special interest in patient wellbeing as well as complex medical care, chronic care management, shared decision making with patients, and genetics. With more than 30 years in clinical practice, she is considered a master clinician/diagnostician. In the management of chronic disorders such as chronic insomnia and chronic pain, she believes in the integrative approach which focuses on exercise, nutrition and mental health and minimizes medicinal interventions.
