Established in 1996.
A-1 Guaranteed began in a small garage of Richard and Krissy’s home in Vallejo while they were pregnant with their 3rd child. Unable to run the business from their home anymore (diesel trucks and delivery vans were visiting daily) the business moved to Commercial Street. The business quickly outgrew this building and in 2004 the existing building at 1768 Broadway in Vallejo was purchased. Currently over 30 people are employed, and the Hiteshews have 4 adult children, 3 of which are employed within the company in addition to a brother, nephew and niece of the Hiteshews.
