Building Beautiful Landscapes Since 1994

Tim’s Lawn Service was started in 1994 when, Tim Slane Jr. began mowing his neighbors’ lawns at age 11. By high school, Tim was a teenaged entrepreneur. He attended the Frederick County Career and Technology Center to study landscaping.

Tim Jr. also works as a career firefighter for a neighboring county. In 1999, Tim Jr. received a chapter award in Agri-Entrepreneurship by the Kauffman Center for Entrepreneurial Leadership sponsored by the National Future Farmers of America (FFA) organization. The next year he was awarded the Youth Entrepreneur Award from the State of Maryland. With his business growing rapidly, Tim Jr. enlisted the assistance of his father, Tim Sr., incorporating Tim’s Lawn and Landscaping Service in 2001.
