Tax Consultants since 1984

Strand Boyce O'Shaughnessy, CPAs, Inc. (SBO) is a public accounting firm specializing in helping closely held business and individuals with their tax and accounting needs.


We appreciate the confidence our clients place in us, and we do not take it for granted.  We believe that the most important thing we can do for our clients is to help them plan for the future.  We believe it is important that we work as a team with your other financial advisors (estate attorney, insurance agent, and investment advisor) to achieve a cohesive financial plan.  We encourage our clients to seek advice before entering into transactions, rather than after.  It is easier to plan ahead than attempt to make the best of a situation after the fact.

We help you find solutions to the financial and tax issues that arise in your business and personal life.

If your actions inspire others to dream more, learn more, do more, become more, you are a leader
— John Quincy Adams
