Debbie Zajac, CPA

Client Accounting Services Manager

“The difference between ordinary and extraordinary is that little extra." Jimmy Johnson

I joined Johanson & Yau in 2016 in a hybrid role, providing tax and client accounting services. As a QuickBooks® ProAdvisor, I provide a full-service approach to the unique tax and accounting needs of small business and high-net-worth family clients.

My career began as an IRS agent, prior to working for a Big Four firm and later leading the tax practice for a small local firm. I was fortunate to take time away from work to raise my children before continuing my career.

I have lived in the Silicon Valley for most of my adult life. Outside of work, I enjoy traveling, kayaking, spending time with my significant other and our collective adult children, attending Cal football games with college friends and even dusting off my piccolo to march at our annual Alumni Band Day.
