HAGÅTÑA, Guam (BoG) — Bank of Guam, along with its Board of Directors, is proud to announce the following promotions and additions to the Bank of Guam Familia.
For over 53 years, Bank of Guam has been guided by a simple but powerful purpose: to serve the people and communities we call home. That commitment is especially meaningful in our neighboring islands, where our presence goes beyond just our branches and banking services, but our relationships and trust with our people.
“Today, we’re proud to celebrate some incredible leaders who not only bring decades of experience in the banking and financial industry, but who deeply understand the needs of their communities — places where they were born, raised, and have a deep connection to serving. As The People’s Bank, it is the People behind us that sets us apart. We don’t just operate in the region, we live here. We believe in hiring locally, promoting from within, and continuing to invest in leaders who embody our commitment to serve, uplift, and grow with our people. Congratulations to Marcie, Dave, Jennifer, Ryan, and Rington!” said Joaquin P.L.G. Cook, president and chief executive officer, Bank of Guam
