In 2014, the Christopherson family partnered with Greg Windisch and Brian Flahavan to form the “Synergy Group". Synergy Group takes its name from the “synergy” between its operating companies, as well as the "synergy" between its customers, employees and business relationships.


Synergy’s primary focus is on its development business, which has been rebuilding throughout Sonoma County since 2017, helping families move back into their homes quickly through their All-Inclusive Rebuild Program. The most recent large development project is “Village Walk”-- a 46 home subdivision in downtown Cotati. We have successfully completed over 100 entry-level to high-end, custom "transformations" over the past six years! The local real estate communities, as well as home buyers, recognize and respect the design, specifications and thought that goes into creating a gorgeous "transformation" or remodel. This extra effort has transformed Synergy Group into a recognized and respected brand within the North Bay's real estate community.


The Synergy Team understands how successful communities are built. Synergy partners, Andy Christopherson, Greg Windisch and Brian Flahavan have assembled a full staff of longtime industry veterans that provide the depth of knowledge necessary to build out successful projects. Synergy prides itself on strong relationships with the local and regional trade base, as well as the local governments.


As the developer and builder of many landmark communities, the entire Synergy team, working with our widely respected, long-standing trade partners and employees, understand how successful communities are built. And as a local, family-run business with deep roots in Sonoma County, we know the importance of providing families with quality-built, eco-friendly homes in sought-after locations. We deliver what home-buyers desire most today: quality, high-end finishes, functionality and energy- efficient, green technologies that can be seen throughout each new Synergy home. We are committed to building on our history of excellence by delivering superior homes with unparalleled service, each and every day.
