Meet our hard-working team of volunteers!

Maggie Ardito
Marguerite (Maggie) Ellen Ardito, President, Co-founder, Director

Maggie is an active advocate for trails and cycling. She believes that active mobility and safe, bikable, walkable places, are keys to a healthy, active, self-reliant, sustainable and equitable future for individuals and communities. She advocates low-speed pedal-assist bicycles (Class 1 e-bikes also called ped-elecs), cargo bikes, folding bikes and other personal transportation innovations.  In addition to her dedicated work with the River to Sea Loop Alliance, she also serves on the board of directors for the River of Lakes Heritage Corridor Florida Scenic Byway, which follows the path of the Loop.  

After a long career with high-tech companies such as Harris and Computer Sciences, and owning a government contracting company that specialized in data and knowledge management, she is now enjoying an active semi-retirement. In 2004, after 35 years as a software and systems engineer that included 3 year tours in Munich and Seoul, she founded a company specializing in enterprise information architecture and semantic technologies, providing consulting services to help national intelligence agencies make better use of their information. Since retiring, she and her husband Jim have focused on cycle touring, and trail exploration and advocacy. They have explored many of the destination trails in Europe and North America, studying various approaches to bike-friendliness.

Ryan Gravel
Ryan Gravel – Advisory Board

Ryan Gravel, AICP, LEED AP, is the founding principal of Sixpitch and creator of the Atlanta Beltline, the reinvention of a 22-mile circle of railroads that began as the subject of his master’s thesis.  A designer, urban planner, and writer, he is increasingly called to speak to audiences across the world on topics as wide ranging as transportation, public health, affordable housing and urban regeneration.  Ryan lives with his family in Atlanta.  

Atlanta Beltline is changing both the physical form of his city and the decisions people make about living there. Now a $4 billion public-private investment in the early stages of implementation, the project’s health and economic benefits are already evident through record-breaking use of its first section of mainline trail and $3.1 billion of private sector redevelopment since 2005.

Ryan has received numerous awards and press related to his work on the Atlanta Beltline and tells his story internationally, but an essential aspect of his work is yet to come. Alongside project work at Sixpitch and research on similar “catalyst infrastructure” projects around the world, he makes a compelling case about what this movement means and why it matters. In his book“Where We Want to Live,”, Ryan investigates the cultural side of infrastructure, describing how its intimate relationship with our way of life can illuminate a brighter path forward for cities.
