In 1978 she earned a diploma in Law Enforcement/Park Management and was commissioned as a Park Warden and Law Enforcement Officer for the Maryland State Park Service at Cunningham Falls State Park. It was in this role that she developed her lifelong love of nature. In 1986, Mary Ellen began a career with the Maryland Department of Transportation, State Aviation Administration at Baltimore/Washington International Airport.

From her time as a Park Ranger, Mary Ellen developed a life long appreciation of nature and wildlife.

In 2008, she succeeded in building her dream home; a log cabin in Smithsburg, MD just over a mile from the park in which she began her career; in close proximity to Camp David, which we affectionately refer to as "Camp Hope".
