As St. Louis-based Enterprise Bank & Trust took over Los Alamos National Bank over Memorial Day weekend, converting accounts had a few wrinkles, and some ATM cardholders couldn’t get cash or use their debit cards.

“Some ATM-only cards [without debit card functions] were not working, so these customers had to come into the branch to get cash,” said Steve Richardson, vice president of marketing at Enterprise Bank, which now owns the six former Los Alamos National Bank branches in Santa Fe, Los Alamos and Albuquerque. “Also, some debit card transactions at certain retailers were being declined.”

The debit card issues were resolved and the ATM-only cards were working by May 30, he said.

The issues affected less than 1 percent of the 60,000 individual accounts in New Mexico that were converted from Los Alamos National Bank to Enterprise Bank & Trust, he said.

“Other issues have been limited or one-off situations that we’ve addressed as they came up, and we continue to be available should any other customer have an issue,” Richardson said.

Clayton, Mo.,-based Enterprise Financial Services in November announced it was acquiring Los Alamos-based Trinity Capital Corp., the parent company of Los Alamos National Bank for $213 million. Along with the six New Mexico branches, Enterprise Bank & Trust has 21 branches in St. Louis, seven in the Kansas City metropolitan area and two in the Phoenix area.
