Linda Smith

One of Linda's first memories of Stonegate Drive is planting daffodils in the woods in preparation for building her contemporary home there (and getting a bad case of poison ivy because she didn't wear gloves!) She and, her late husband, Gene became residents in 1973. With the help of the Greater Stonegate Village, Linda plans to age in place here for the indefinite future. Linda taught English at High Point High School before becoming its first magnet school coordinator.  After her retirement as an educator, she became the Executive Director of the Mead Family Foundation, which funded programs for children, families, and the arts in the District and Montgomery County. Thanks to appearing in over two dozen community theater productions, Linda has been a queen (Eleanor, Lion in Winter), a President's wife (Abigail Adams, 1776), a psychic (Helga, Death Trap), charmingly eccentric (Mame) and cannily insane (Ethel, Curious Savage). 

Shawn Burns

Shawn Burns grew up in the high deserts of New Mexico after his family moved there in 1969. In 1995, after completing his engineering education, Shawn joined the technical staff at Sandia National Laboratories in Albuquerque, New Mexico. During his career as a researcher and manager within the Department of Energy’s National Laboratory System, Shawn would regularly travel to the Washington, DC area. With growing appreciation for the beauty, history, and vibrancy of the State, Shawn made a permanent move to Maryland in 2020. Shawn came to Stonegate with his wife Guinn in 2024 after falling in love with our beautiful and neighborly community. Shawn values the aims of the Village movement after witnessing his own parents’ challenges with aging in place and in anticipation of he and Guinn facing similar challenges in the coming years. Shawn appreciates the opportunity to apply his organizational experience and analytical skills to benefit the Board of the Greater Stonegate Village, as a way to contribute and give back to our shared home. In his free time Shawn enjoys traveling with Guinn, cooking, and making a general mess in his shop.
