About Us

Sydni Tangaro - sydni@tangaro-cpas.com


Sydni received her accounting degree from Montana State University and started her career with a fantastic firm in Florida.   She has loved public accounting since then.  She enjoys the variety of working on different challenges with different people and companies to help them achieve their financial success.  For family reasons, she took a hiatus from public accounting from 2006 to 2013 and worked as a Contract Controller for various private companies.  She was excited to go back to public accounting in early 2014 and thrilled to start the firm on May 31, 2017.  Sydni believes in working hard and playing hard. In addition to accounting, Sydni enjoys spending time with her family and friends, travelling, hiking, reading, and movies.
