George Thomas Leach, “Tom”, of St. Charles, IL, passed away Friday, August 22, with his loving family by his side.
The son of the late Harry and Vivian Leach, Tom was born August 20, 1940, in Bemidji, MN. The family moved to Golden Valley, MN nine years later.
He attended Pillsbury Military Academy where he was a member of the Crack Squad and later attended Golden Valley High School. At Golden Valley, at the age of seventeen, Tom met the love of his life, Katherine Wilson.
In his youth he discovered his lifelong love for drumming and jazz music.
After high school, Tom attended the University of Minnesota.
Tom joined the Navy Air Reserves after college. After six months of training in electronics and sonar, he served for three years as a member of the Navy Air Reserves flying in anti submarine aircraft: P2V Neptunes and S2Fs. He was a lifelong lover of planes and a lifelong proud Navy man.
On September 14, 1963, Tom married the center of his world, Kathi, at St. Paul’s Episcopal church in Minneapolis. They were married for 61 years.
Professionally, Tom was a highly successful sales and marketing executive. He sold complex scientific equipment such as electron microscopes and mass spectrometers to universities, sometimes calling on Nobel laureates. He continued his executive career in the medical industry in the areas of staffing, mobile MRI, and mobile CAT scans.
He worked tirelessly in his career, providing wonderful lives for his wife, son, and daughter. In his free time, he enjoyed sailing the family’s liveaboard sailboat on Lake Michigan and he enjoyed their beautiful property in St. Charles.
Tom was preceded in death by infant daughter and son David, brother Richard, and sister Barbara.
He is survived by wife, Katherine, daughter Amy Leach and son-in-law Dave Wong, sister Mary Leach and niece Mary Stasson.

"My deepest condolences to you Kathi, Amy, and Dave! I'm glad for the conversations I got to have with Tom over the years and to hear him speak at so many Leach Cups. The world is a little less bright without him in it. I hope you all are finding some comfort in your joyful and loving memories of him."
