Pinnacle is absolutely fantastic! We used to have them at our home in the Sacramento area (they have a branch up there as well) and when we moved to the Bay Area we were super happy that they service the East Bay as well. I can't speak highly enough about Pinnacles customer service, amazing office staff, fantastic on-site technicians who actually CARE about their clients.. This is good old fashioned customer service, the way it sssgrSHOULD be… A+!
