Les was the son of Maxine Galer Jansen and John W. Jansen. He had an older brother Doug, and sisters Cathy and Terri. Les graduated from North High School in 1981, where he excelled in choir and band (trumpet and French horn), and earned his Bachelor's degree from the University of South Dakota in 1985. After graduation, he returned to Sioux City, helped to care for his mother who suffered from a long-term illness and worked as a bookkeeper, restaurant manager, and clerk. For the past decade, he worked for Hy-Vee, at its location at 27th and Pierce Streets.

Les enjoyed helping others and treasured the relationships he was able to build with the friends he served. During the worst of the pandemic, he never hesitated and arrived at work every day, even arranging delivery of essential items to residents at a nearby assisted living home to limit the exposure of those were might be vulnerable to infection. He will be greatly missed by his family, friends, and those who got the chance to know him.

He is survived by three siblings and their families – his brother Doug Jansen and his wife Emery, of Austin, Texas; his sister Kathy Zellers and her husband Kevin of Bismarck, North Dakota; and his sister Terri Johnson and her husband Ron, of Surprise, Arizona, and many nieces and nephews.

In lieu of flowers, memorials may be directed to Hospice of Siouxland.
