Soldata Energy Consulting was founded in 1980 in Santa Rosa by Bill Mattinson, widely respected for his knowledge and service in the field of building energy analysis in California.

Throughout his career, Bill was active in helping to shape building energy policy in both state and national arenas. When he took his much deserved retirement in Spring of 2013, the longtime working relationship of Sarah and Sean transitioned to a business partnership. Over the next decade, they navigated SOLDATA through complex code changes, economic challenges, natural disasters and the global pandemic, enabling SOLDATA to emerge as strong as ever.

Sarah has recently retired and moved on to attending her garden as her regular “job.” The strength of SOLDATA continues on presently and towards the future with the ongoing collaboration between our dedicated consultants and clients. Thank you!
