Sequoia Senior Solutions, Inc. was founded in March of 2003 by Gabriella Ambrosi and Stanton Lawson. The husband & wife team began offering services to seniors in Petaluma working out of their home for the first few years until the business grew to the point of acquiring office space. In 2007 Sequoia Senior Solutions acquired its largest competitor, Home Care Options, and overnight the company grew from less than 100 caregivers to over 300. By then, its territory had grown to include all of Sonoma, Marin, and Napa counties, and the acquisition added Lake and Mendocino Counties to its growing service area. In 2009 the company expanded into Solano County as well. The company remains headquartered in Petaluma with a satellite office located in Lakeport and Santa Rosa.
