"The Presidio of San Francisco, being a historical site, has very particular and stringent requirements for construction projects and Data and Telecommunications Services as well. Rosendin Electric's Network Service Division tackled the project head on and fulfilled 100% of our requirements, and dealt with many unknowns and constraints of the historical environment. Their expertise, workmanship, and overall service response exceeded our expectations."
