Welcome About TenThreeTwenty Operating Instructions Search


Welcome to First Potomac. We're happy to have you as a tenant here at the TenThreeTwenty Building. First Potomac began in 1997 when our founders, Doug Donatelli and Nick Smith, started out with just four properties. First Potomac now encompasses over 10 million square feet of office and business park properties throughout the region.

If you've relocated to our property from outside of the First Potomac portfolio let your previous neighbors know they're welcome here. We're always happy to work with new tenants, especially ones that come to us from trusted sources, like you. Our office space spans Class A, LEED Platinum to business parks located throughout the greater Washington region and we are always just a phone call or email away.
