Accountants and Advisors to Silicon Valley Since 1979.

Our History

Back in 1979, Silicon Valley as we know it was barely recognizable. Darrell Johanson and Anthony Yau were colleagues and partners at a large international accounting firm when they began to articulate an idea. This idea, their vision, was all about providing a more personalized approach to client service. It would begin with strong relationships and expert abilities to produce effective, meaningful results on behalf of their clients. Today, we continue to advance this commitment to detail and personal relationships as we provide service to individuals, families and privately-owned businesses throughout Silicon Valley and beyond.

Our Values

Ethics & Integrity

Exceptional Client Service

Professional Growth

Community Stewardship

Our Team

You deserve the best. At Johanson & Yau, we listen carefully, explore options and solve problems. When you are willing to share our mission with friends and family, that’s the ultimate compliment.

Our ongoing participation in professional, industry and community organizations also expands our networks and knowledge base – delivering deeper insights and a more proactive approach to client service. As a member firm of BKR International, a global accounting association of 160 independent firms in 80 countries, we regularly collaborate with other member firms and pursue additional technical training opportunities.
