The Marshfield High School Alumni Luncheon began in 2010 as an annual spring gathering of Blue Jay Alumni following the discontinuation of the annual Marshfield High School Alumni Banquet (several years previous). Following the discontinuation of the Alumni Banquet there was no longer an organized reunion of MHS Alumni. Thus, several former members of the banquet committee came together to plan an annual alumni luncheon during the Missouri Cherry Blossom Festival as the newly formed Marshfield High School Alumni Association. The charter luncheon committee was composed of the following MHS Alumni: Nicholas W. Inman (President-Class of 2000), Joyce (Ellis) Smith (Secretary-Class of 1948), Colleen (Alexander) Meyer (Treasurer-Class of 1948), Dr. Tommy Macdonnell (Class of 1941) and Freda Leota “Tody” Clair (Class of 1951). The first committee meeting was held in the home of Joyce (Ellis) Smith and the committee decided to plan an annual luncheon program made complete by honoring a distinguished alumnus at each event. They also voted to work on reintroducing the MHS School Song in the Marshfield R-1 School District. The school song was officially adopted by the MHS graduating class of 1926.
Later, Darleen (Gower) Anderson (Class of 1951), Peggy Don (Day) Yates (Class of 1966), Carmen (Layman) Graybill (Class of 1953), Martha (Andreatta) Myers (Class of 1959), Betty (Muse) Price (Class of 1961), Lola Belle (Graves) Underwood (Class of 1954), Marthann (Shook) Hoover (Class of 1951), Lynda (Davis) Clair (Class of 1960), Linda (Rost) Dickinson (Class of 1970), Laurabeth (Bagley) Smith (Class of 1968), Vivian (Smith) King (Class of 1963) and Diana (Campbell) Hudspeth (Class of 1958) would join the luncheon committee throughout the years.
In 2017, Maggie Peterson Mancuso (Charlene Darling, Andy Griffith Show) performed at the luncheon and in 2019, Lulu Roman (Hee Haw) performed as well. Alison Arngrim (Nellie Oleson, Little House on the Prairie) greeted alumni at the 2021 luncheon.
In 2021, the alumni association voted to begin a new tradition of presenting honorary diplomas to deserving individuals, former students, community supporters and retired educators. The first recipients were Dee Lewis (Class of 1951) and Bill Walker (Class of 1953). Lewis and Walker were both retired educators from Marshfield High School and they were presented their honorary diplomas by a representative of the above-mentioned graduating class. In 2022, Robert “Junior” McDonald (Class of 1949), Roberta (Teague) Rozell (Class of 1951) and Judy (Alexander) Young (Class of 1961) were chosen. In 2023, Michael Speer (Class of 2000), Emma Bell (Class of 1984), Shirley Mae Day (Class of 1953) and Doris Ann (Banta) Hunt (Class of 1959) were selected to be presented honorary diplomas.
