Debra THOMAS Obituary




Debra Lynn Thomas (nee Koser), age 62 of Delafield passed away with her loving family by her side on Monday, July 31, 2023.  Deb was born on October 10, 1960 in Racine, WI to Albert and Bernice (Peters) Koser.  She married the love of her life James P. Thomas on June 16, 1984 in Racine, WI.

Debbie grew up on an airport in Yorkville, WI and attended Union Grove High School where she was active in cheerleading and yearbook and met and married her highschool sweetheart. She graduated Summa Cum Laude from the University of Wisconsin-Milwaukee and also later received her Masters Degree in Curriculum and Instruction. Widely recognized as a master educator, she taught both the hearing impaired and elementary students.

Debbie had many superpowers, including impeccable preparedness, an uncanny skill to find the best parking spot, and most of all her ability to connect with people on a personal level. From strangers at the supermarket to the hundreds of children she taught in her 40 year career, her charisma and sense of humor brought joy wherever she went.

Dubbed the pre-internet Pinterest queen, she was known for her sewing projects for the 4H, homemade cabbage patch dolls for her nieces, elaborate scrapbooking, and throwing parties where no detail was missed. Her creativity spread to a number of volunteer activities including leading Vacation Bible School in Waunakee, and serving with the Lake Country Women’s Club.

Debbie had a spunky stubbornness and was never susceptible to peer pressure. She loved traveling but hated flying. She loved a Badger football game, as long as they were ahead by at least two touchdowns. But most of all she loved time spent with family, playing Euchre or Catan, and doting on her grandchildren.

Deb is survived by her loving husband of 39 years, Dr. James Thomas; her children, Ben (Kristen) Thomas, Dr. Lauren (Brian) Kroll and Rachel Thomas; her 2 grandchildren, Isla and Emmett; her sister, Karen Magee; her mother-in-law, Judith Thomas; her 19 loving nieces and nephews; other relatives and a host of friends.

Preceding her in death are her parents, Albert and Bernice Koser and her father-in-law, Leo Thomas.
