In 2014, the Christopherson Family partnered with Greg Windisch and Brian Flahavan to form the “Synergy Group”-- a real estate, construction management and development company. 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, Synergy Communities, and currently has three communities in process in Sonoma County. The most recent development project is “Village Walk”-- a 46 home subdivision in downtown Cotati.

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.
