Founded in 1986 by the late Gregorio C. Sanchez, Marianas Credit Bureau Inc. (now widely known as MCB) has been a pioneer in financial technology, committed to protecting businesses and consumers. Gregorio recognized the financial risks merchants faced due to NSF checks and the growing threat of identity theft. His innovative solutions, including the MCB Check Guarantee Card, transformed financial transactions by incorporating a photo ID and magnetic stripe, allowing merchants to electronically verify check-writing privileges and safeguard their businesses.
Under Gregorio’s leadership, MCB introduced groundbreaking advancements. In 1990, the MCB Check Guarantee Card evolved into MCB Plus, enabling members to make fuel purchases at all gas stations across Guam. Along with his son, Michael Sanchez, they expanded this system to offer custom fleet card services for local fuel companies, enhancing convenience and efficiency for businesses.
By 1995, Gregorio foresaw the need for an independent yet shared local network to route ATM and POS transactions on Guam, reducing costs for financial institutions. This vision became a reality in 1996 with the establishment of Mari-Net, which kept switching services local and provided significant savings. His daughter, Beth Lizama, successfully managed Mari-Net for over a decade, ensuring its growth and reliability.
Nearly 40 years later, Gregorio C. Sanchez’s legacy continues through his family. His granddaughter, Lisa Sanchez Alicto, now leads MCB’s efforts in card innovations while upholding the values and vision he instilled. As a multi-generational family business, MCB remains dedicated to serving companies and families across Guam, the Marianas Islands, and the Western Pacific.
For decades, the Sanchez family has upheld the principles of innovation, service, and community support, ensuring MCB evolves with the changing financial landscape. Their unwavering commitment to excellence has solidified MCB’s reputation as a trusted financial partner.
MCB stands as a testament to Gregorio C. Sanchez’s enduring vision—fostering trust, innovation, and growth across generations in the region.
