Armed with engineering and business degrees from Stanford, Steve has worked in the software industry most of his career. A skeptic by nature, he denied anthropogenic climate change until 2005 when the weight of supporting scientific evidence clearly overwhelmed his arguments against it. Since then he has worked to reduce his own carbon footprint, performed a number of greenhouse gas (GHG) inventories for his home town of Los Altos Hills, and researched innovative methods of reducing energy waste in local high energy homes.

Steve started collaborating with Acterra in 2009, convinced that combining Acterra's expertise in community outreach with his vision of an online residential energy auditing tool could save significant amounts of energy and GHG emissions while also lowering residents' utility bills.

Davena Gentry has been a volunteer with Acterra's Green@Home program since 2009. Not only has she done over 23 HouseCalls, but as Menlo Park's “Kit Manager,” she keeps the HouseCall tool kits organized and stocked for volunteers serving Menlo residents. Davena is passionate about helping others reduce their carbon footprint and jumped at the opportunity to join Acerra's High Energy Homes team.

Since moving to the Bay Area 30 years ago, Davena has been involved in various San Mateo County organizations. As an advocate for the environment, she's been Site Captain for the California Coastal Cleanup at Bedwell-Bayfront Park for the last two years. She is also a member of the Menlo Park Green Ribbon Citizen's Committee.

In addition to her work at Acterra, Davena is a certified EcoBroker and holds the National Association of Realtors GREEN designation. From her years working as a Peninsula-based Realtor, she understands and is knowledgeable about the five communities that HEH is designed to serve.

In her spare time Davena enjoys birding, hiking, gardening, music and dancing with her partner, Jonathan, and walking their Westie, Reggie!

Nancy has a degree in Industrial Engineering and, thus, is an efficiency engineer. She has also been an environmentalist her whole life as a result of her mother’s teaching her at a very young age to leave things better than she found them. When she was in high school, she built a solar water heater and helped organize Earth Day at her high school. At Stanford, her final IE project was improving the efficiency of the university’s recycling center. Having spent many years since Stanford as a for-profit engineer, working on everything from designing nuclear power plant control rooms to teaching computer classes to founding a multimedia company, Nancy is now focusing her energy, time, and passion on the environment. She joined Acterra in 2011 as the High Energy Homes Assessor and Support.

Nancy is a volunteer for Acterra’s Green@Home program and a graduate of Acterra’s Be the Change program. She is also an Encore Fellow at Art in Action in Menlo Park, where she is learning about managing a non-profit. She and her partner are native plant gardeners and are trying to bring sustainable thinking to the neighborhood.
