Our Staff

The Habitat team is comprised of office staff and volunteer committee chairs. Working together, they coordinate the day-to-day operations of the organization, including program management, business operations, bookkeeping and volunteer services. They raise funds and approach trade and business suppliers to arrange tax-deductible in-kind material donations. They work in partnership with local churches, businesses, organizations and civic agencies to develop safe neighborhoods so that hardworking, disadvantaged families have access to quality, affordable homes.


Donations of nearly all office equipment and furniture, coupled with the efforts of our volunteers, enable Habitat to keep administrative costs very low. We are nationally ranked for sound fiscal management.

We would like to thank Sam Bishop of Connected Web Solutions for providing content managment tools for maintaining our website, and also Anna, a dedicated and talented volunteer website developer. The overall website design was generously donated by Salt Communications.  Habitat Lehigh Valley's Board of Directors wishes to thank all of them for their efforts and demonstration of social responsibility in support of the Habitat mission.
