Our Founders

Eric Kilbride and Raul Ratcliffe met in 1995 when Raul came to Indianapolis to conduct Community YouthMapping training, while working for the Academy for Educational Development's Center for Youth Development and Policy Research.  As a result of this project the two instantly became champions of positive youth development.


In early 2000, Eric joined Raul at the Center in Washington, DC and together they brought Community YouthMapping and other positive youth development strategies to thousands of young people around the world.


In 2013, Eric and Raul formed a US-based, small business to bring the best and brightest positive youth development professionals together to more effectively and efficiently serve young people.
