Jennifer Toole founded Toole Design Group in 2003 with a mission to create dynamic communities where walking, biking and transit use is possible for people of all ages and abilities. Since then, she has assembled a talented group of planners, engineers and landscape architects who share her passion for producing the highest quality work for each and every client, and her commitment to innovative, yet realistic solutions that improve community health and quality of life. Toole Design Group maintains a unique blend of local, state and national expertise – ranging from designing sidewalks and trails to preparing national policy and best practice guidance. Some of the firm’s first projects included Washington, DC’s transformative Bicycle Master Plan, and the subsequent design and construction of an extensive bicycle network in the Nation’s Capital.

Since the firm's early days in a small office on Main Street in Laurel, Maryland, Toole Design Group has grown to a thriving business with offices across the United States and projects throughout North and South America. Toole Design Group’s client list now includes many of the nation’s largest cities, such as Denver, Minneapolis, Seattle, Dallas, and Boston; as well as numerous small communities, counties, state DOTs and regional planning organizations.
