Wescom Central Credit Union in Pasadena, still struggling with the Southern California recession, said last week that it plans to shutter another eight branches.
The $3 billion-asset credit union had already shut 19 branches over the past two years.
The new round of closings would reduce its branch network, which numbered 56 in 2007, to 29.
Wescom, which once had assets of $3.8 billion, has been among the credit unions hit hardest by the region's economic downturn.
It lost $63 million last year and $67 million in the first nine months of this year.
Several other credit union retrenchments were announced last week. Arizona Federal Credit Union said it was closing eight branches, Elevations Credit Union in Boulder, Colo., announced layoffs and a branch closing.
