About Us

In 1975, Andrew Joseph Brennan Sr. and Andrew Joseph Brennan, Jr. formed what is now Brennan Machine Company Incorporated. Brennan Machine officially became a corporation in 1985. Since then we have grown extensively, and have relocated twice in order to support our expanding facilities. In 1997, we moved to our current location, 820 Monponsett Street, Hanson, MA. Our facility hosts 23 CNC machining centers, providing high quality precision machining of metal and plastics. Today we serve several long-time customers in various industries including commercial, medical, military, and semiconductor. We continue our commitment to growth by regularly training our staff, expanding our capacity, and exploring new capabilities.

Our Mission: To maintain a high level of quality, on-time delivery, and customer satisfaction while pursuing continual improvement.
