Zimmerman, John Jack Charles

John “Jack” Charles Zimmerman

February 7, 1947 - July 22, 2020

John “Jack” Charles Zimmerman passed away on July 22, 2020 in Allen, Texas. He was born on February 7, 1947 to John Joseph Zimmerman and Vivian (Yetter) Zimmerman in Cincinnati, Ohio. 

Jack spent many years working in industry in a financial capacity, and his career took him all over the world.  He lived in Tokyo, London, San Francisco (which always held a special place in his heart), Los Angeles, and Las Vegas. After a long career in finance, he decided to obtain a doctoral degree and embarked on a career in teaching.  Although his primary reason for going into education was to honor his late parents, who had always wanted Jack to become a teacher, he found teaching to be a meaningful and rewarding second career in which he flourished and excelled.  He taught a multitude of business classes and was able to teach almost any subject because of his broad experience and the key positions he held in numerous companies including GE, Caterpillar, Intel, Level One Communications and iSuppli. Jack taught at Pepperdine University, Roseman University in Las Vegas, Zayed University in Abu Dhabi, Argosy University, and finally ended his career at Collin College after moving to Texas in 2013. He taught at Collin College until the time of his death.

Most important to Jack was his family. He and his wife Katherine Walker met in 2003 in Los Angeles and married in Las Vegas in 2006. Jack and Kathy shared a love of travel and were fortunate to travel extensively, particularly in the years when they lived in the Middle East. In their 17 years together, they shared everything and saw the world together. It was a wonderful life.

Jack took tremendous pride in the beautiful women in his life.  He had a particularly close relationship with his daughter, Amy Dahlin. His granddaughters, Alexa and Emma, were the light of his life.  He was so proud of their many accomplishments and always marveled at the amazing and talented women they had become. Jack was also close to his brother, Dave Zimmerman, who just last year gave him the gift of life when he donated stem cells when Jack was diagnosed with leukemia. He was also tremendously proud of his nephew, Adam Zimmerman. 

Jack is survived by his wife, Katherine Walker of Allen, Texas; daughter, Amy Dahlin and husband, Darrick of Orlando, Florida; granddaughters, Alexa Dahlin of Birmingham, Alabama and Emma Dahlin of Orlando, Florida; brother, Dave Zimmerman and wife, Missy of Taylor Mill, Kentucky; nephew, Adam Zimmerman of Taylor Mill, Kentucky and a host of other loving family and friends.

He was preceded in death by his parents, John and Vivian.

Due to current circumstances, no services are planned and the family will come together for a celebration of life at a later date.  The Collin College Foundation has established a memorial scholarship fund to honor Jack. In lieu of flowers, donations to the scholarship fund would be greatly appreciated. Please see the link below.
