Theresa Pilgrim

Assurance Manager



Theresa joined Geffen Mesher in 2019 after working for over a decade in the private and public accounting sectors. Her professional experience began with more than 4 years in federal healthcare reimbursement, starting with cost report auditing for a federal healthcare agency and transitioning to cost report preparation for a local public accounting firm. She then performed audits, reviews, and compilations as well as tax services for 6 years for a variety of industries, including healthcare, professional services, and real estate. Since transitioning to Geffen Mesher, her focus has shifted to the assurance side of accounting.


In Theresa’s current role as assurance manager, she serves the real estate and professional services industries, specializing in employee benefit plans and HUD-assisted projects. She has been a member of the Oregon Society of Certified Public Accountants (OSCPA) since 2010 and currently serves on the OSCPA’s Business Management & Advisory Services Committee. She has been a member of the American Institute of Certified Public Accountants and the Portland chapter of Women in Insurance and Financial Services since 2020.


Theresa is a graduate of Creighton University and holds dual BSBA degrees in Accounting and International Business.


Theresa has been volunteering with the Junior League of Portland since 2012, where she currently serves as the Finance Committee Vice-Chair. For after-work enjoyment, she likes hiking, cycling, exploring new restaurants, and playing trivia with her husband and their friends.
