Erin Louis, CPA, President and Founder

Erin (she/her) has over thirteen years of experience working with individuals, nonprofits and campaigns and has been a CPA since 2011. She got her start specializing in tax preparation for registered domestic partners and same-sex married couples before marriage equality. She was so passionate about spreading good information about a confusing topic that she became a blogger: you can read her past articles at Financial Queeries. Erin has served as Treasurer on the Board of Directors of Budd Bay Rugby Football Club, Capital City Pride and Stonewall Youth and has served on multiple committees to the Greater Seattle Business Association's Board of Directors. In her early days in the industry she was an instructor for the Washington State Society of CPAs’ Financial Literacy Program and is a current member of the American Institute of CPAs. Prior to accounting, Erin was a professional Texas Hold ‘Em poker dealer and still regularly visits Las Vegas to play. Don’t worry, she doesn’t gamble when it comes to accounting.
