Since mid-2023, the team has been equally focused on neutralizing the balance sheet for a stable or slightly declining interest rate environment going forward."

"MainStreet Bank is a community bank built upon great relationships, and this continues to be a true testament to our financial strength. Our balance sheet continues to grow through the many thoughtful referrals from our existing customers and from our reputation in the markets we serve," said Abdul Hersiburane, President of MainStreet Bank.
