Robert James Cash

Robert (Bob) J. Cash, 85, passed away at his home surrounded by love, prayers, family & caregivers May 25, 2024 following a valiant battle with Parkinson’s Disease.

Bob was born on June 15, 1938 in Mitchell, South Dakota to Robert C. Cash and Helen Barber Cash. He attended high school in Woolsey, South Dakota, and pursued higher education at the South Dakota School of Mines. He furthered his academic pursuits at Iowa State University in Ames, Iowa earning both a Master of Science, and a Doctorate in Nuclear Engineering.

It was during his time at Iowa State that Bob met his wife, Donna Bloemer. They were married on June 19, 1965 in Louisville, Kentucky, and their union was blessed with four children: Theresa Bousliman (Mike), Robert L. Cash (Lynnette), Sharon Thornton (Marty), and Matthew Cash and grandchildren Megan Bousliman, Jessica Bousliman, and August Thornton. Bob was a devoted husband, father, and grandfather. He cherished every moment spent with his family.

Professionally, Bob distinguished himself as a process engineer and project director at Hanford, where he contributed significantly to the closure of seven major safety issues, including the renowned burping tank SY-101. Outside of his nuclear engineering career, Bob was known as “The Pool Doctor,” maintaining numerous swimming pools in the Tri-Cities area.

A devout member of Christ the King Catholic Church, Bob served as a Eucharistic Minister. His dedication extended beyond the church walls into various volunteer activities, including coaching AAU track, judging science fairs, and serving on the boards of Community Concerts of the Tri-Cities, and Allied Arts Gallery. Bob and Donna were instrumental in the inception of the CK Sausage Fest and served as directors of Art in the Park for nine years.

For the past 3 years, Bob participated in a study trial involving a pump for delivering medication to Parkinson’s patients demonstrating his commitment to science.

Bob’s passions included camping, travel (especially cruises), and fixing anything that needed repair and some things that didn’t.

He is survived by his loving wife, Donna, their four children, three grandchildren, two sisters—Marlys Marso and Marilyn Schwans (Ron)—as well as numerous nieces and nephews. Bob was preceded in death by his parents and brother-in-law Kenny Marso.

A special thank you to Bob’s team of nurses and caregivers from Positive Nature Home Care and Tri-City Chaplaincy Hospice. He would not have been able to stay at home without their professional and loving care.

A Rosary will be held on June 5, 2024 at 10:15am and a funeral Mass at 11:00am at Christ the King Catholic Church. A reception will follow in the gathering space. Inurnment will take place at Sunset Memorial Gardens at 2:30 pm.

In lieu of flowers, donations may be made to Christ the King School, 1122 Long Ave., Richland, WA 99354 or the Parkinson’s Foundation,
