A fantastic team — each bringing their experience and gifts to support our work.


Rolando Zeledon, Executive Director

Rolando has extensive experience in the nonprofit sector. In 1999 after completing his undergraduate and graduate work in engineering from Stanford University and successfully launching a small business, Rolando joined the Schools Online development team. As Regional Program Director, he later coordinated the installation of thirty-eight Internet Learning Centers in under-resourced urban and rural schools in Spain, India and Latin America.

Before coming to BCM in 2006, Rolando was Executive Producer at Plugged In, an East Palo Alto nonprofit that empowered people “to produce, create and contribute using technology.” There he led the growth of a community portal, EPA.net, and re-launched the teen youth media program, Young Producers. He joined BCM after his tenure there, quickly filling the role of Director of Operations. In 2008, he became the Executive Director.

On a personal note, Rolando and his wife, Dolores, are proud parents of Sophia, Raquel, Christian, and Paulina.


Amy Joh, Director of Partner Development

Amy Joh has served BCM in a variety of capacities since moving to East Palo Alto in June of 2000. She directed StreetWorkz, BCM’s teen ministry, for five years and then served as BCM’s Director of Ministries. Amy is currently the Director of Partner Development, overseeing the training and support of BCM’s staff, interns, fellows, volunteers, parents and short term mission groups.

Amy grew up in McMinnville, Oregon and graduated from Whitman College in Walla Walla, Washington before moving to California. She and her husband, Steve, have two daughters, Bethany and Kyra. Amy enjoys reading, gardening, camping, running and playing soccer in her spare time.


Andrew Hartwell, Director of Ministries

Andrew was one of BCM's founders and served as Executive Director until 2008. He moved to Austin, Texas and worked in a variety of educational settings and consulting projects. Some of the consulting projects were exciting -- especially working with Abundant Life Christian Fellowship in the Bay Area and with The Refuge (Home for Domestic Minor Victims of Sex Trafficking) in Austin -- but they were short-term.

In January 2018, he began working with Austin Bridge Builders Alliance (ABBA). He loved the work of building coalitions among Christian leaders from churches, business, non-profits and government. Unfortunately, in June, ABBA's board created an entirely new direction for the organization. This led to a parting and a new job search. That's when Andrew received the newsletter celebrating Cassie Arnold as she stepped down from the Director of Ministries position. That led to a conversation with Rolando Zeledon, which led to an application and interview process that has resulted in Andrew returning to BCM as the Director of Ministries. He is excited to work with the program team, renew relationships with families and leaders in the community, and to participate in the great work God continues to do through this ministy.
