Arthur Keith Thomassen

March 1, 1933~January 4, 2022

Arthur Keith Thomassen passed away peacefully Tuesday, January 4, 2022 in Layton Utah at 88 years young. He passed of natural causes. Although he will be greatly missed, he had many family and friends waiting for him on the other side.

K. as he was known, was  born at Dee Hospital in Ogden, UT on March 1, 1933 to Arthur W. and Barbara B Thomassen. He was the oldest of three sons.  He was an active kid and spent his youth enjoying the creeks and landscapes of the greater Kaysville area. He graduated from Davis High School in 1951.  After graduation he joined the United States Army, where he served honorably, stationed in Alaska. He then returned back home to Kaysville for a short time before leaving again to serve an LDS mission to the Central States.

After completing his LDS mission, he attended college at BYU and went on to earn a Bachelor of Science degree in Sociology from Cal State-Fullerton.

K had a big heart and loved helping people no matter their circumstances.  His career in social work gave him many opportunities to serve others. K always seemed to go above and beyond, especially for his special needs friends that he worked with daily.
K was a lifelong member of The Church of Jesus Christ of Latter day Saints. He strived to live a Christlike life and was willing to do anything asked of him.
K loved the outdoors and had many hobbies that took him high into the mountains or swimming in the sea.  K had a passion for gardening, and it was rare to see him sitting still. He was always active and on the lookout for any interesting rock or piece of wood, no matter the size, that he could bring home and appreciate further. He participated for many years in the Senior Olympics in many different events with softball being his favorite.

He is survived by his loving wife, Mardel. Although they met later in life, they shared many adventures and enjoyable times together.

Dad is loved by many and will be missed by his five surviving children,
Kalyn Thomassen, Paula Thomassen, Nancy (Rich) Skaggs, Keith Thomassen, & Kregg (Kami) Thomassen.  His legacy lives on through his grandchildren and great grandchildren.
He was preceded in death by his son, Dean (Lynda) Thomassen.
