Program accomplishments
- The American Contract Bridge League Unit 503 is an organization which promotes the play of duplicate bridge. It is comprised of 10 bridge clubs and is the largest ACBL Unit in the San Francisco Bay Area. Recreational and educational opportunities are provided for Unit 503's approximately 800 bridge club members, other ACBL Bay Area Units' 5,300 members, as well as the general public, to learn and play the card game of bridge. During 2025 duplicate bridge games were held either face-to-face or online at multiple times each day, up to seven days a week. The Unit rents a facility in Mountain View, CA where face-to-face bridge games are played. In 2025 the bridge club held 12 two-to-five-day face-to-face bridge tournaments. Throughout the year face-to-face bridge lessons were held at the club. Additionally, the Unit held six Zoom bridge lectures, given by world-class bridge expert celebrities, and attended by as many as 150 students, as part of the club's bridge education program. The Unit has a mentor program and held three Pro/Am games in which experienced bridge players partner with less experienced players to improve their skills. A large library of bridge books is available for members' learning. The Unit's website is extensive and contains information about the Unit's activities, bridge game schedules and results of daily games, bridge lessons and learning opportunities, and the Unit's governance. The Unit's president publishes a monthly letter, which updates club members as to the club's activities and upcoming events. The Unit also contributes a column to the bridge District newsletter, published regularly and free to members, which contains club news, upcoming events, and bridge-related information of interest to club members. Silicon Valley Youth Bridge offers after-school bridge programs, bridge mentoring events, and other opportunities for youth to learn the game of bridge, all held at ACBL Unit 503's Bridge Center. These include weekly Casual Fridays, Pizza Party bridge tournaments, and Summer Camp bridge classes. The Unit membership and guests are largely seniors, and the Unit provides a social environment where members and the general public can meet new people, make friends, pursue a hobby, play an entertaining card game, and keep mentally sharp.Expenses $176,714
