Cultivated by Three Generations

Ottawa Corporation is a precision CNC machining company located on the shores of Grand Haven, Michigan. For over fifty years we have been serving our customers with high quality tight tolerance machined solutions to meet the needs of our customers. Michael E. Papanoli founded Ottawa Manufacturing in 1958 based on an idea to improve the paper drill machining process.

In 1968 the name was changed to Ottawa Corporation which it has remained since. Michael J. Papanoli, purchased the business from his father in 1999 and currently owns and runs the day to day operations. With the addition of his son Emmanuel in 2010, Ottawa is entering its third generation of serving our customer's needs.
