Our Staff

Susan K. Speer, CPA

After graduating from the University of Idaho with a degree in accounting in 1994, Sue started her career with Arthur Andersen in Boise.  While at Arthur Andersen, she spent a bulk of her time working with the family wealth planning department on planned giving projects and charitable entity returns and with the state and local tax department working with multi-state income tax issues.


Sue spent the next 8 years in northwest Washington working for a small CPA firm. Since the community was largely rural, she focused on helping farm and other small business clients with multi-generational tax and financial issues. While in Mount Vernon, Sue served on the local chapter’s board of the Washington Estate Planning Council and held a variety of positions for the Washington Society of CPAs, including local chapter president and member of several state-wide committees.


She had the opportunity to return home to Boise in 2003 and join Reagan, Parks & Associates, P.A. While at RPA, she has developed a practice that includes clients from a variety of industries and backgrounds – artists, doctors, engineers, and teachers, just to name a few. Sue appreciates the opportunity to help her clients plan for the future rather than merely reporting their financial pasts. She feels very fortunate to continue to work with a large volume of her Washington clients and visits them a few times a year.


Sue is a member of the American Institute of Certified Public Accountants, the Idaho Society of CPAs, and the Boise Estate Planning Council.
