"Both banking institutions are well-known for their excellent customer service and community advocacy, which will not change as a result of the Merger and Bank Merger. Once approved, the Merger and Bank Merger will complete another step in our long-term strategy to increase our presence throughout California's Central Valley and fill in a gap between our existing offices in Sacramento and Modesto, allowing Central Valley Community Bank to further accommodate a growing customer base in this region and throughout the Valley.

"Service 1st Bank's quality service standards, philosophies and corporate culture are consistent with Central Valley Community Bank.

Brooks, chairman of the board and CEO of Service 1st Bancorp and Service 1st Bank.

"Over the past eight years, Service 1st Bank has provided exceptional community banking service of the highest caliber to residents and businesses, allowing rapid and successful growth in San Joaquin County.
