Don was born in Brooklyn, New York on January 5, 1934 to William and Elizabeth (Ginnitty) Grennon. After serving in the U.S. Army, he attended St. Francis College and graduated with a Bachelor of Science degree in Accounting. He started his career as an accountant with Arthur Andersen. After Arthur Andersen, he was a sales manager for Great Northern Nekoosa Corporation and Georgia Pacific until his retirement.

In addition to treasuring time with family and friends, he loved to play golf, cheer on his favorite sports teams, spend time at the beach, devour books on history, and dance The Lindy.

He will forever inspire us to celebrate the little joys in each day and to battle adversity with strong faith and good humor.
