Andrew Alonso – Personal Banker

Andrew grew up in Southern California before relocating to Spearfish in the summer of
2019. He spent two years as a bank teller at another financial institution before joining
Pioneer Bank & Trust as a personal banker in June 2025. Drawn to Pioneer Bank & Trust for
its strong community involvement, Andrew is passionate about growing both within the
bank and alongside the community it serves.
 
Outside of work, Andrew enjoys making the most of every season—hiking, golfing,
watching baseball, and traveling during the summer, and snowboarding once winter rolls
in.
