Denise M. (Koch) Matthes

Denise Marie Matthes, 69, of rural North English, Iowa, passed away early Monday morning, November 3rd, at her home after a courageous battle with breast cancer.

Denise was born May 4th, 1956, the oldest child of Dennis and Donna Koch. She grew up on the family farm and graduated from Dike High School, Class of 1974. Denise was an accomplished pianist, attending the prestigious Interlochen in Michigan. She also played oboe and clarinet and was the drum majorette for the Dike High Marching Band. Denise was an excellent athlete in softball and basketball, later playing college basketball at Grand View. She married Mike Matthes in 1980 and the couple were blessed with two sons, Matthew and Michael. After living in Alaska for a time, they returned to their acreage in Iowa in 1985. Denise and Mike enjoyed watching their two boys play college football and go on to coach various Raiders teams. Recently, Denise and Mike love supporting their three grandchildren Ellie, Jenna and Marcus in their various extra-curricular pursuits from 4-H to sporting events.

Denise’s pride in her Danish heritage brought her to Denmark twice in the last decade visiting her Danish relatives. Always a wonderful daughter and sister, Denise talked to her Dad and siblings almost daily. She also was strongly connected to her nieces and nephews, often sending them cards and notes of encouragement.
