Timothy J O'BrienFounder, Senior Tax Specialist, CRTP
Prior to creating his tax practice, Tim honorably served in our military. He served two tours in Vietnam in 1967 and 1968. After the military, he took positions with United Airlines and then Eastman Kodak. Tim graduated from San Jose State University in 1971, receiving a bachelor degree in Business Administration with an emphasis in tax.
In 1972, shortly after graduating, Tim ambitiously founded Timothy J’ O’Brien Tax & Accounting and began his accredited career as a tax preparer. He had no office when he started, and rather drove door to door making house calls to all of his clients. By 1975, Tim had obtained his master’s degree in taxation from Golden Gate University and his practice continued to flourish.
In August of 1990, Tim acquired Dell Harris tax practice. The acquisition left Tim with nearly 1,000 clients and one of the largest, privately run tax practices in the bay area. In 2004, Tim sold his practice to his nephews, allowing Tim to have a more flexible schedule and continue to work in the industry he loves. He continues to serve as a Senior Tax Preparer and Advisor, with over 40 years of experience in tax practice management, preparation and law.
