Commercial Bank & Trust of PA opened its doors for business in May 1934 at the Latrobe office of the former Peoples National Bank, a building that serves still today as the bank's main retail office and administrative headquarters. Through the years, Commercial Bank & Trust established a strong reputation for leadership in the development of a wide range of banking and financial services. To provide round-the-clock service, automatic teller machines (ATMs) are available at all of our community banking offices and at a number of offsite locations.
