administrative staff

Steve Callander, Executive Director
Joined BDN: 1998

303-442-7605 ext 4

Steve has dedicated his career to supporting low-income children and families across the globe, in places as varied as rural Appalachia; Cuernavaca, Mexico; Cape Town, South Africa; and dozens of cities across Turkey. Starting as a counselor for youth in crisis, he realized that many children’s lives would be radically different if they had access to quality child care and family support. Therefore, Steve shifted his energy to early intervention programs like Early Head Start, Part C, and community health centers serving profoundly disabled children.

With an MA in Nonprofit Management and BS in Psychology & Human Services, Steve gravitated to administrative roles to impact support systems.  He set his sights on the Executive Director position at BDN, understanding the gravity of managing a century-old organization. Following in the footsteps of those who served before him, Steve devotes his time to innovation and advocacy for Early Childhood Education.

During his tenure, BDN has integrated infant care into its programming, expanded the number of families served, as well as become a founding member of Boulder County’s Early Childhood Council - a task force focused on comprehensive ECE systems development. The task force was so successful that it became a part of Colorado statute. Steve’s efforts have garnered community recognition, and he was awarded Colorado Trust Fellow, Rotary International GSE Fellow, and United Way Spirit of the Community of the Award.

In his spare time, Steve enjoys skiing (he was formerly a National Ski Patrol member, as well as instructor for kids and paralyzed skiers), fly fishing, hiking, and building everything from robots to couch forts with his daughter.
