MedStar St. Mary's Hospital

Collaborating for the best patient care

Nestled in the waterside community of Leonardtown, Maryland, we are a full-service community hospital, delivering state-of-the-art emergency, acute inpatient, and outpatient care. With innovative technology and a dedication to excellence, our staff is committed to providing you and your family quality care with a compassionate touch. 

With more than 1,100 associates, MedStar St. Mary's is one of the largest employers in St. Mary's County. From diagnosis to treatment and recovery, our skilled professionals work together to make your experience the best it can be. 

Not only will we meet your medical needs, but we'll offer you the dignity, comfort, and support you deserve during trying times.

Investing in our community

As a not-for-profit hospital, earnings are reinvested in our community and into improving patient care. Health Connections, our outreach program, promotes healthy living through seminars, classes, support groups, health fairs, and demonstrations. 

Free and low-cost programs are offered on the hospital campus and in the community.

MedStar St. Mary's upholds its tradition of caring by continuously promoting, maintaining, and improving health through education and services while assuring quality care, patient safety, and fiscal integrity.  


Our vision is to be the trusted leader in caring for people and advancing health.


When you visit our hospital, we want you to feel like an honored guest. This is a time of physical and emotional need, and we are here for you. Not only will we meet your medical needs, but we'll offer you the dignity, comfort, and support you deserve during trying times. 

To make your guest experience the best it can be, we value Service, Patient First, Integrity, Respect, Innovation, and Teamwork (SPIRIT).

Celebrating a century of caring

We were established in 1912 by a group of seven founders to be a place where people could receive quality medical attention in a setting of comfort and caring. And while a great deal has changed in health care and medical technology, MedStar St. Mary's is still a place of compassionate, quality care that would make our founders proud. Throughout 2012, we celebrated our century of caring for you — our neighbors, friends, and family members. In the more than 100 years that St. Mary's has been a part of the Southern Maryland community, our goal has remained the same: to deliver a positive healthcare experience to our patients and neighbors.
