About Us

NORCAL Voice and Data has been in Business since April of 2001. Owned and Operated by Theresa DeCarvalho at its inception, NORCAL is a very small minority of Women Owned Businesses (WBE) in the C-7 low voltage data communication arena.


NORCAL had the huge challenge, and uphill battle of substantiating itself as a technical services organization just as the dot com bubble burst.


By having a two pronged approach to its services, C-7 contracting coupled with technical services for small to mid-size businesses, NORCAL navigated through the worst technical bubble burst in history. Countless technical companies folded over the following years, creating the toughest marketplace ever for technology based companies; NORCAL survived.


Charles Davidson, the C-7 license holder for NORCAL, worked for three years as a contractor for Pacific Bell and five years as an employee. During that time he was part of an 8 person team which managed 423 NT servers over 7 states. This multi master domain covered their corporate headquarters in Bishop Ranch, San Francisco, Southern California, and Sacramento. During his tenure at Pacific Bell Charles managed logistics and implementations of infrastructure in data centers, deployment and configuration of workstations and servers, while learning the standards and design of corporate data networks.
