Sarah Cristina Herrera is a Certified Public Accountant with nearly two decades of experience in small business accounting, beginning her career in 2005 and earning her CPA license in 2017. She specializes in nonprofit and small business accounting, bringing deep technical expertise together with real-world operational insight.

Sarah actively serves her profession and community.

Her board service reflects her strong commitment to governance, compliance, and financial stewardship.

As a small business owner herself and a longtime Sonoma County resident, Sarah understands firsthand the financial challenges and opportunities facing local organizations.
