    About Us

    NorthBay biz is a monthly business-to-business magazine, covering Napa, Sonoma and Marin counties. This year, the magazine is celebrating 44 years of continuous operation. The magazine hit the stands in 1975. Known then as Sonoma Business, the magazine offered exclusive coverage of Sonoma County. In 2000, the magazine was up for sale and three business partners—Norm and Joni Rosinski, and her brother, John Dennis, purchased the magazine with the intention of continuing the magazine’s well-established history in the business community. Two years later, the name of the magazine was changed to NorthBay biz to cover an expanded market.

    November 9, 2017, marked another momentous event in the magazine’s notable history when it was purchased by Amaturo Sonoma Media Group. ASMG owns and operates a number of stations in the North Bay, including News/Talk KSRO, Froggy 92.9 FM, KHits 104.9 FM, Hot 101.7 FM and 97.7 FM The River, reaching more than 200,000 adults each week.

    Today, the magazine has more than 50,000 readers, and is committed to fresh ideas, supporting the vitality of the region as well as responsible reporting, in-depth analysis, and top-notch coverage. NorthBay biz is also dedicated to serving the best business interests of the community. It publishes 15 issues each year (12 monthly issues, plus three bonus issues). In recent years, the magazine underwent a complete redesign as well as featuring additional and improved content and a new tagline: Helping your business grow isn’t just something we do…It’s all we do
