Jim was born on June 28, 1936, in Green Bay, Wisconsin. At age 18, he enlisted in the
U.S. Army and proudly served as a military police officer with the renowned 1st Infantry
Division in Germany from 1954 to 1956. He returned home to Green Bay after completing
his service.
Jim’s love story with Sarah began in 1958 when they shared their first dance at the
Lorelei Inn on New Year’s Eve. They married on April 23, 1960, and embarked on a
remarkable adventure together for 63 years.
A lifelong entrepreneur and self-employed from the age of 29, Jim founded Jamestown
Homes, building homes in Green Bay and Allouez. He also served as the president of
both the Brown County Homebuilders Association and Allouez Kiwanis Club. Both a
licensed pilot and avid Packers fan, Jim would pack the family van each summer and,
with Sarah, take the Kubiak children on memorable adventures, visiting 47 states and
Upon “retiring” from their family appraisal business, Kubiak Appraisal, Jim and Sarah
continued their annual adventures to visit the remaining U.S. states and journey across
the globe, exploring 42 countries from Brazil to China. Traveling yearly between Green Bay and Phoenix, Arizona, Jim devoted his time to Sarah and their eight grandchildren and great-grandson. From preschool pick-ups and sleepovers to high school and college graduations, Jim and Sarah were present and
provided love and guidance at every milestone in their family’s lives.

Despite facing health challenges for three decades, Jim’s family attribute his long life to
his tenacity, endless curiosity, deep love for his wife and family, and the unwavering
support and expertise of his doctor of thirty years, Matthias Fuchs, M.D.
