Our History

Our History

Walter A. McKinnon Associates, Inc. is an established Consulting Firm offering an array of structural and architectural engineering services. In January of 1966 long time Weymouth resident Walter McKinnon started his engineering firm Walter A. McKinnon Associates. With its first home being in Braintree the firm was relocated in 1978 to 278 Washington Street in Weymouth. In a nondescript office converted from an original cape style home the company would perform a wide and varying range of engineering services for the South Shore Community. Well known to the local builders and contractors, a standard open door policy for any technical questions or advice has long been the case for our company.

In 1992 Walter’s son Richard took over the reins of the company. Walter would stay on as chief engineer while Richard would steer the firm in the next century while still holding onto the original principles that the company was founded on. Sadly, Richard passed away from a chronic illness in October of 2013. The company would then be put into the care of long time employee and product of Weymouth, Michael Schilling. In January of 2014 Michael purchased the company from the McKinnon family and in 2015 Walter McKinnon officially retired from the company at the age of 91. Michael Schilling, the current principal engineer, has been with the company since 1997.


Michael Schilling is a graduate of Northeastern University with a bachelors degree in Civil Engineering as well as a graduate of Wentworth Institute of Technology with an associates degree in Architectural Engineering.

Mr. Schilling is a registered professional engineer (registration number 51900) in the State of Massachusetts and the registration is current and in good standing.
