The U.S. First Credit Union, based in San Mateo, is opening a new branch at Laurelwood Shopping Center Monday at 3 p.m. including an 24-hour ATM.

The grand opening event will also launch the credit union’s Community Cash game. Customers who open checking accounts in November at U.S. First and who fill out a Community Cash game card with stamps from merchants in the Laurelwood Shopping Center will receive $25 cash in their new account, $25 in printed Community Cash coins to spend at Laurelwood and a $25 donation to San Mateo’s HIP Housing project.

In addition, the Sobranto Family Foundaiton will match U.S. First’s donations to HIP.

U.S. First serves residents of San Mateo, San Francisco and Marin counties. The credit union will open its second branch in San Francisco later this year and a third branch in the Daly City/Colma area in 2008.
