Why choose us

MedStar St. Mary's Hospital is a full-service community hospital that upholds its tradition of caring by continuously promoting, maintaining, and improving health. Whether you require emergency or surgical care, imaging and X-rays, physical therapy, or many services in between, our hospital places a priority on delivering a safe and positive healthcare experience.

Founded in 1912, our hospital is a not-for-profit facility delivering emergency, acute inpatient, and outpatient care. Our committed healthcare providers and team members strive to put the patient first in every way.

We are committed to nurturing new providers to offer convenient access to specialty care close to home. Through the MedStar Health network, we are closely tied to academic hospitals, including MedStar Georgetown University Hospital and MedStar Washington Hospital Center; patients can be quickly transported if a higher level of care is needed.

We received an "A" for patient safety in the Leapfrog Group's Hospital Safety Grade for six consecutive cycles. Our hospital has less layers of personnel, so we are often nimbler to change—and have participated in many trials for products and protocols under consideration for all of MedStar Health.
