Donald Eddie Klostreich

Donald "Coach" Klostreich, beloved educator, coach, and mentor, passed away on
April 22, 2026, in Yuma, Arizona. Born February 8, 1940, in North Dakota, Don spent
his life shaping young minds and inspiring athletes through his love of education and
sport.

Don earned a bachelor's degree in education from Jamestown College where he was a
standout on the Jimmies’ football, wrestling, and track teams. While coaching wrestling
at the University of North Dakota he earned a master's degree in physical education,
and an additional master's from Northern Arizona University.

Affectionately known as "Coach K",  Don left an indelible mark on the athletic programs
of numerous schools where he taught and later volunteered. These included Minot High
School in North Dakota; Carl Hayden High in Phoenix; Sunnyside High in Tucson; Kofa
High and Yuma High in Yuma; San Pasqual High School in California; and Gila Ridge
High in Yuma. His achievements as an athlete and coach earned him widespread
recognition and respect: induction into the Arizona Coaches Association Hall of Fame
and the University of Jamestown Athletic Hall of Fame, the Lifetime Achievement Award
from the National Wrestling Hall of Fame, and the honor of Arizona Wrestling Coach of
the 20th Century from the Arizona Interscholastic Athletic Association.

Don also served his country with pride in the Army National Guard, boxing for their
North Dakota team, and was a member of American Legion Post #157 in Horicon,
Wisconsin.

He is survived by his wife of 35 years, Faith (Wagener); daughters Traci Cromwell, Holli
Bean, and Kelli Klostreich; son Brian Klostreich; nine grandchildren; seven great-
grandchildren; sisters Dorene Steckler and Diane Klostreich; brother Wallace Klostreich;
and many nieces and nephews. He was predeceased by his parents, Ernie and Leah
Klostreich; brother Bill Klostreich; and nephews Jason Klostreich and Page Klostreich.

Don's legacy lives on in every athlete he coached, every student he taught, and every
life he touched. A celebration of life is planned for May 23, 2026. In lieu of flowers, the
family asks that donations be made to your favorite local high school athletic program.
