What is concierge medicine?

An endocrinologist’s role as an educator, guide and the patient’s best advocate is at risk in today’s medical landscape. Mounting administrative tasks take time once devoted to patient care. In a concierge or membership, medicine practice, the doctor makes a commitment to limit the number of patients to ensure adequate time and availability for each patient, and to provide an enhanced level of care.

Extended, unrushed visits enable physicians to spend meaningful time with patients, build relationships, and provide more comprehensive and proactive care. To make this possible, the patient pays an annual fee.

Please call my Patient Information Line to learn more about my concierge medical practice (571) 418-4565.

Best appointment ever! Finally, an endocrinologist who is not only knowledgeable, but one who really LISTENS and tries to connect the dots. She is also empathetic, understanding, an extensive note-taker, and great at asking all the right questions.

Congratulations to Dr. Armellini!
She was voted Washingtonian Top Doctor 2019 by her peers!
