Philosophy of Care
“My philosophy of care centers on empathic patient-centered communication. I partner with my patients and the entire MedStar Health clinical team to ensure our patients receive the highest-quality care.

“There are thousands of things that can happen in the skin, which can be confusing and frustrating for patients. I am a general dermatologist first and foremost. My role is to provide clarity for patients about their condition and to figure out the best treatment options.

“Each person is unique and the approach to skin conditions in each person is equally unique. I believe in an individualized approach to care.”

    Dr. Larson is excellent, one of the best doctors I have ever had.

  • Jun 11, 2026

    Dr. Larson, and her resident and med student, were absolutely wonderful. Their teamwork resulted in a follow up visit that could not have gone better. I feel very fortunate to be able to see Dr. Larson. She is knowledgeable, warm, thorough, patient and a great listener, always giving thoughtful responses to questions, and allowing me to participate in developing a care plan.
