We provide a more comprehensive solution for the small business client by managing the entire network rather than just the problems. We believe that the best computer networks are pro-actively managed using published best practices and years of experience.

Microsoft Small Business Specialist

Microsoft Certified Systems Administrator

Citrix Certified Administrator

Cisco Certified Network Associate

Cisco Certified Design Associate

Altiris Certified Engineer


Originally from New York City, Eric has made Sonoma his home (see, it's in the domain name!) He has been solving computer challenges and building networks since 1982. Eric has worked with every version of MS Small Business Server and participated in numerous Microsoft Beta programs. He is a resident of the City of Sonoma and enjoys mountain biking and music.
