Board of Directors

Sierra Watson

Sierra King Watson was born and raised in Berkshire County. While still attending High School at Mount Everett, she started her career with Salisbury Bank and Trust (SBT) and began learning the dynamics of banking. She has since been with SBT for 8 years and served many different positions.


Sierra has participated in many community events, lending her skills and time while also building relationships throughout the business community. Many of her mentors and friends have inspired her to participate more in the public sphere, and she feels that serving on the board of BerkShares will be a great introduction to board service, and a way to help develop future changes to our community.
