207 McPherson St, Suite B, Santa Cruz, CA 95060, USA

Allterra was founded in 2004 by brothers James and Nathaniel Allen. Allterra began as an environmental engineering firm that investigated and remediated dissolved contaminants in groundwater. Clients include agriculture, energy, and public agencies. In just a few short years, the company successfully investigated and closed 30 groundwater contamination cases in the SF Bay Region.

In 2009, Allterra launched its solar division to accelerate the adoption of renewable energy on the central coast. Allterra’s unique data driven approach and unparalleled customer service has fueled the company’s success. In 2012, Allterra Solar was awarded Best Solar Company in Santa Cruz County by readers of the Good Times and Santa Cruz Sentinel, titles that have yet to be relinquished. Subsequent awards include Best Place to Work in Monterey Bay by Monterey County Business Council and 2015 Cool Climate Leader by California Air Resources Board, an award earned by only five other companies in California.
