Our Founder
Mikhail Zadoyen (1963-2017)
Mr. Zadoyen was born in 1963 in the beautiful city of Odessa, Ukraine. He immigrated to the US in 1994 with a massive background from the soviet and post-soviet financial system. Graduated from H&R Block Accounting School in 1996 and was invited to work in one of the bookkeeping firm in the Valley area.
Very soon he realized that he is more than capable to open his own business and that is how Mikhail Income Tax Inc was born.
During his years as a business owner, he became an Enrolled Agent to Practice Before The IRS, serving the clientele on the highest level possible.
For almost 20 years Mikhail was one of the leading accountant and tax preparer in Los Angeles.
