Dr. Pepperell diagnoses and treats patients with severe and rare or complicated infections, including antibiotic-resistant infections.

She guides doctors and care teams from diagnosis through treatment throughout a patient’s hospitalization and follow-up visits.

Taking a holistic approach to care, Dr. Pepperell consults with other doctors and specialists and integrates leading-edge information and therapies into care plans. She finds the solutions that work best for each patient’s needs. Dr. Pepperell listens compassionately to her patients and their families and explains conditions and treatments in understandable terms.

Outside of work, Dr. Pepperell likes to spend time in the outdoors and enjoys a wide variety of outdoor activities.

I often treat patients when they’re gravely ill, but the most rewarding part is getting to know them personally as they start to feel better and recover.
