Dr. Olsen provides a full scope of services, from routine procedures to advanced gastroenterology treatments. She has a particular interest in:
- Esophageal disorders

She embraces a holistic, team-based approach to achieve optimal health outcomes through multimodal care plans that often involve lifestyle interventions alongside medical treatments. For complex cases, Dr. Olsen readily involves a multidisciplinary team of MedStar Health physicians and experts.
Dr. Olsen received her medical degree from the University of Health Sciences College of Osteopathic Medicine in Kansas City, Missouri. She completed her internship, residency, and fellowship at the University of Medicine and Dentistry of New Jersey in Stratford, New Jersey.
