First American Bank of Virginia, Northern Virginia's largest bank, has named President and Chief Executive Officer Milton L. Drewer Jr. to the added post of chairman.

Drewer replaces H. Paul Mount, who retired after 50 years with the bank.

Drewer, 62, is a former William and Mary athletic director and head football coach who became a public relations vice president for Clarendon Bank & Trust Co., a predecessor to First American, in 1964. A bank spokesman described Drewer as a key player in the flurry of acquisitions that have made First American one of Virginia's largest banks.

First American of Virginia, formed in 1978 by the merger of three Northern Virginia banks, started with 45 branch offices. Since December 1983, it has added 51 offices statewide and recently reported record assets of $2.1 billion. Drewer, who had been chairman and president of Clarendon, became the bank's first president in 1978.

Drewer was an athletic coach and teacher in Virginia public schools until becoming backfield football coach for the University of Richmond in 1956, and then athletic director at the College of William and Mary. Drewer also has served on the boards of local companies, industry associations and nonprofit groups.

In a separate announcement, First American Bank of Virginia appointed Anthony Torentinos vice president and director of personnel. Torentinos had been a regional director of human resources for the former Mercantile Texas Corp., a bank holding company.

First American Bank of Virginia is the largest subsidiary of the D.C.-based bank holding company, First American Bankshares, which also owns First American Bank of Washington, First American Bank of Maryland and banks in New York and Tennessee.
