Andy's Bio

From 2008 to mid-2013, Andy was a Sustainable Building Specialist for the Alabama Association of Habitat for Humanity Affiliates, where he provided training and certification in energy efficient practices and techniques for the 34 Habitat for Humanity affiliates statewide. In that job, he also designed HVAC systems for Habitat affiliates across the United States.

Andy's involvement with Habitat for Humanity goes back even further, as he spent three years as the Executive Director of the Lee County Alabama Habitat for Humanity in Opelika, Alabama. When he took that position in 2002, the standard building specifications represented state of the art practices...for 1985. During his time with this HfH affiliate, Andy improved the specifications in many ways, using high performance rather than aluminum-framed windows, for example, and was also involved with the first home in Alabama to qualify for the ENERGY STAR label in 2002.

Prior to relocating to Alabama, Andy spent the years 1993 to 2001 working with Casas por Cristo in Juarez, Mexico as the Program Manager (3 years) and Executive Director (5 years). Under his leadership the ministry moved from building basic shelter to insulated, air-sealed structures, which improved the comfort and health of the families they served. Volunteer teams from across North America built more than 1200 homes during his time there. The organization also completed projects in El Paso County, Texas including a straw-bale house in San Elizario.
