Allen Wesley Posthumus, age 92 of Buffalo, MN, and formerly of Stillwater, MN, and Port Isabel, TX, passed away February 19, 2023.

He was born on March 13, 1930, in Halstad, MN, to William and Florence (Vork) Posthumus. Allen spent most of his childhood in Walnut Grove, MN, and then graduated with the class of 1948 from Minneapolis South High School. He furthered his education at St. Cloud State Teacher’s College where he received his undergraduate degree. It was there that he also met his future wife, Joyce Overmeyer, and the two were joined in marriage in Redwood Falls, MN, in 1952. They would go on to share 66 years of loving matrimony.

Allen continued his education (summers) in Greeley, CO, where he earned his master’s degree, and then attended the University of St. Thomas in St. Paul for his specialist degree. He was an elementary school principal and central office administrator for several districts, including the Centennial District, St. Louis Park, North St. Paul, and Stillwater. Although he retired from education in 1993, he was always a teacher at heart. Allen was an outstanding motivator and role model, and always encouraged others to reach their full potential.

Allen loved the outdoors and spent much of his spare time either fishing or boating. When the cold weather arrived in Minnesota, he and Joyce made their way to Port Isabel, TX, to spend the winter months in warmer climates. Allen loved Texas, both for the many wonderful friends he made in the community and for the ample fishing opportunities presented by the Laguna Madre. He spent more than 20 winters in his beloved “sea cottage.”

Allen and Joyce’s faith was important to them, and they were devoted members of Buffalo United Methodist Church and First United Methodist Church in Port Isabel.

Allen’s family was his main priority in life, and those fortunate enough to call him father, brother, grandfather, or great-grandfather can attest to the many ways he drew his loved ones together. Whether he was taking his wife and children down the Mississippi in a 20-foot runabout or renting out a houseboat for four generations of the Posthumus family to enjoy, Allen found ways to create familial bonds and lasting memories.

He is preceded in death by his wife Joyce, his brother Warren, and sisters-in-law Alice and Eleanor Posthumus.

Allen is survived by his sons, Dirk (Jean) and Dan (Cheryl); grandchildren, Anna (Matthew) Deutsch, Steven Posthumus, Laura (Paul) Lundberg, Kelly (Landon) Moline, and Kristin (Elijah Kracht) Posthumus; four great-grandchildren; brother, Gerald “Dutch” Posthumus of Rochester, MN; and many other relatives and friends.

Visitation will be held Friday, February 24, 2023, from 5:00 PM – 7:00 PM at the Buffalo United Methodist Church (609 8th St NW, Buffalo, MN 55313). Additional visitation will take place Saturday, February 25, 2023, at 10:00 AM, with the memorial service beginning at 11:00 AM, lunch to follow, all at the church. Interment will be held at Lakeview Cemetery in rural Maple Lake/Silver Creek, MN. In lieu of flowers, memorials may be directed to Buffalo United Methodist Church or First United Methodist Church in Port Isabel, TX, or to the charity of your choosing.

Funeral arrangements have been entrusted to The Peterson Chapel of Buffalo. Online condolences for the family may be directed to

    I am sorry to be seeing this so late. What an amazing man. I was fortunate enough to have him as both a teacher and principal in Marine on St. Croix in elementary school. He taught me so much at such a young age. Many of the things he taught, I still use to this day. In addition, by his example, he showed me how to be a good person. I am very sorry for your loss.
