www.middlefieldbank.bank “In 2008 I put together an aggressive growth strategy for my business Exscape Designs. The need for a local relationship based approach made clear sense. In my experience over the years with Middlefield Bank we have been able to achieve a lot of growth together. With Middlefield you're not just numbers, it's the relationship and community that matters to them.” “Ease Logistics was looking for a small community bank to help us grow our business. We needed a credit line to support our 40% growth. Middlefield bank was able to step up and provide us the working capital we needed and the process was seamless. When Ease Logistics needed a mortgage for their new headquarters in Dublin, Middlefield Bank was there. We love the staff too!” “It has been a pleasure to do business with Middlefield Bank for these past 20 years. When all of the other local major banks turned away from the business, Middlefield Bank welcomed it with open arms. This relationship started with trust and that trust is the foundation in which we continue to use Middlefield for all of our banking needs.” 116 Years Supporting its Local Communities Local Strong Committed
