PSA Insurance & Financial Services traces its roots back to 1928, when Bert Lewis, grandfather of today’s Managing Director Chip Lewis, immigrated to America from Wales. A coal miner in his native country, Lewis settled in Baltimore, Maryland. He soon accepted a position with an insurance company where he sold debit life insurance, knocking on doors each week to collect premiums from his customers. Bert’s son, Trevor C. Lewis, earned an Accounting degree at the University of Baltimore and subsequently joined his father in the insurance industry. During the 1940’s Trevor Lewis established Trevor C. Lewis & Company, an independent insurance agency. The firm was located in the Fidelity Building at Charles and Lexington Streets in Baltimore City
