Patelco Credit Union Headquarters & Corporate Office

About Patelco Credit Union

Patelco Credit Union is a member-owned financial cooperative founded in 1936 by employees of Pacific Telephone and Telegraph Company, which later became part of AT&T. The credit union began with approximately $500 in assets and a small group of employees seeking a cooperative way to save money and access affordable credit. From those modest beginnings, Patelco expanded throughout Northern California and eventually broadened membership eligibility significantly, becoming one of the largest credit unions in the United States.

Today, Patelco is a full-service not-for-profit credit union providing checking accounts, savings, certificates, credit cards, auto loans, personal loans, home loans, home equity products, digital banking, financial education, fraud protection, insurance-related services, investment resources, and other financial products. Current official information reports more than 550,000 members nationwide and approximately 36 branches, including its Virtual Branch. As of September 2026, Patelco reported total assets of approximately $10.07 billion, member shares of approximately $8.49 billion, and equity of approximately $944.9 million.

Patelco remains a member-owned credit union rather than a publicly traded bank or financial holding company. Members collectively own the cooperative and elect directors who oversee its governance. Erin Mendez continues to serve as President and Chief Executive Officer. Patelco’s current headquarters and principal corporate address remain at 3 Park Place in Dublin, California. The organization has also continued strengthening cybersecurity and fraud-protection capabilities following the major 2024 cybersecurity incident, with current fraud programs emphasizing account monitoring, member education, voice authentication, dedicated fraud specialists, and digital transaction-dispute tools.
