More Than Bookkeeping—Strategic Financial Services for Growing Businesses

Sonoma Accounting Group is a relationship-driven accounting firm providing high-level bookkeeping, financial reporting, and fractional CFO services to small and mid-sized businesses throughout Sonoma County and Northern California.

Founded by CPA Brent Garrison, we bring over 18 years of strategic financial planning and operational leadership to forward-thinking companies in wine, construction, agriculture, and manufacturing—as well as other organizations committed to excellence and long-term partnership.
