Gregory Lee Havemann

Gregory Lee Havemann, 63, passed away after a courageous battle with cancer, surrounded by his loving family and friends. He was born on December 2, 1962, in Berwyn, Illinois, the son of Larry J. Havemann and Virginia Carole Hawkins Havemann.

After serving in the U.S. Marine Corps, Greg pursued a career manufacturing parts and assemblies for the aerospace industry. His grandfather was a machinist, and his father was a rocket scientist, so he decided to combine both. He spent the last 25 years in manufacturing and received numerous commendations from several companies including NASA. One of his proudest accomplishments was that his signature is on Mars. As Designer and CEO of AnC Precision Machining, Greg and his team manufactured custom parts and assemblies, which eventually drew him into the plastic tube industry, where he developed patented technologies to revolutionize the industry.

He will be remembered as an amazing husband and best friend, dad, and papa.

He was predeceased by his parents. He is survived by his wife Deanna Couture Havemann, sons Robert Kelly, Joshua Perrone, Gregory Havemann, Zachariah (Kaitlyn) Havemann, Tylor Havemann and Josef Gmuender and loved stepchildren Felicia (Mike) Haupt and Timothy Couture. Best friend/brother Mark Bouma and his brother Larry Havemann. Sisters-in-law Kathy (Bob) Stubbs, Gail (Craig) Walmsley, Phyllis Cardona, Ellen (Jim) Flowers and Brother-in-law Ken (Bernie) Render and Douglas Sutfin.

Greg was a true patriot, loved the USA, loved his Harleys, and his hot rods. A brilliant man loved by many and will be missed terribly.
