Our Offices

The EastCoast Bio offices are located at the “Old Neal Farm” in North Berwick, Maine. In our 1850 vintage converted barn, we combine the best of modern biotechnology with a rich New England history. This historical landmark was originally built to house the oxen used by the state of Maine to build the “Old East Route” to Portland. The barn was then used for dairy cattle until 1978. Our own recently-updated (and thoroughly modern) animal facility is located minutes away from our main offices.
