Dave Roberston

Green Earth Equities, Retired. Coach, Destination Imagination

With decades of energy efficiency, construction, community engagement, and business management experience, Dave brings to CHERP decades of experience, wise council, and a true heart for our mission. Dave spent 30 years as a General Building Contractor and for the last 20 years has focused primarily on reducing the use of fossil fuels in the building sector by applying building science performance metrics to accomplish deep-energy reduction retrofits for buildings. Passionate about the role that contractors can play in fighting global warming and, at the same time, improving the health and quality of life of the people living in his homes, Dave has become a national leader in the building science and construction industry. He served as President of the California Building Performance Association- now Efficiency First California- and received the Tony Woods Award for Excellence in Advancing the National Home Performance Industry. This national award recognizes the single individual who has most advanced the home performance industry over the past year.

Dave then founded GreenEarthEquities, devoted to helping communities in the Fresno area recover from the recession. He bought foreclosed homes and installed complete energy retrofits along with some quality remodeling before selling them to first time home buyers, previously unable to enter the housing market. The concept is a win for all concerned: the homeowner gets an affordable home with lower bills and more comfort, the neighborhood has improved values, the workforce is supplied with green jobs, and the planet benefits from less carbon burned.

Dave followed “the Grand Babies” to Virginia where he and his wife, Luelle, now enjoy their three grandchildren. Luelle’s career as a travel agent causes Dave to investigate energy efficiency and renewable energy projects worldwide as he goes along on those travels and cruises, protecting Luelle from piracy on the high seas.😊

Dave is currently in seminary at The Living School, focused on social justice issues, and a Coach, working with Destination Imagination to inspire and equip our next generation of children to achieve anything they can imagine in life by building confidence and developing extraordinary creativity, critical thinking, communication, and teamworking skills.

Mark Peterson

Citadel Ministries: Non-Profit Organizational Management/Development

Mark has a particularly wide-ranging mix of skill-sets, experiences, and passions that make him a valuable and trusted CHERP Board Member.  With a BS in Industrial Technology/Construction and as a licensed Real Estate Broker, Mark operated his Real Estate and Property Management business rehabilitating over 120 apartment units and houses. He is a building science expert and has been a certified energy efficiency CHEERS Rater since 1991 – one of the first in the profession.

Since the early 1990’s Mark has been following deeper interests in helping to form and manage several non-profit organizations focused on affordable housing, education, employment services, health access, and low-income community development. Over the decades he has developed expertise in non-profit organizational development, program/funding development, grant writing and project management. He currently consults to organizations on non-profit formation, articles/bylaws, Board development, financial planning, government compliance and fundraising/development strategies. He has assisted more than 175 groups in becoming non-profit, tax exempt (501(c)(3) organizations, served on numerous governing boards, and worked in staff positions of Executive Director.


Mark’s perspective has been shaped by a unique combination of private sector/non-profit experience, and an entrepreneurial mind set, experience and skills. CHERP’s mission perfectly overlaps with Mark’s as his continuing interests are focused on community and economic development for low-income cities, neighborhoods, and families.
