Mark Achen, a cherished husband, father, grandfather, brother, and friend, passed away peacefully, leaving a legacy of service, adventure, and an infectious sense of humor. Born in Vancouver, WA, during World War II, he met his veteran father, George, for the first time at age three (an early prime number as he might say)—an experience that shaped his resilient character. As the eldest of seven siblings—Pat, Georgia, Kerry, Gail, Fred, and Heather—Mark infused their childhoods with joy and laughter.
His formative years were marked by a deep commitment to the Boy Scouts, where he not only earned the rank of Eagle Scout but also took part in unforgettable adventures like the 1957 BSA Jamboree and a transformative expedition to Philmont Scout Ranch in New Mexico. In 1960, he achieved the God and Country Award.
Mark excelled academically, infamous for reading the dictionary in his youth. As valedictorian of Evergreen High School in 1961, he earned a full scholarship to Stanford University, where he joined the Phi Sigma Kappa fraternity and dove into tennis and bridge. He later attended the University of Washington and the University of Nevada, Reno, earning a master's degree while serving on the ski patrol. Full of athletic prowess, his racewalking culminated in breaking AAU records while pursuing a doctorate at the University of Missouri and being honored as Racewalker of the Year in 1972.
Mark's life took a beautiful turn when he met his "One True Love," Mary Ann, while working as a Teaching Assistant at the University of Missouri. Their whirlwind romance began in October 1970 and led to a joyful wedding in August 1971. Together they created a life filled with love, travel, and cherished memories for over 53 years.
Professionally, Mark was dedicated to public service, beginning as Assistant City Manager of Ferguson, MO, and later serving as City Manager of Mounds View, MN, where he and Mary Ann welcomed their daughters, Wyndi and Kara. They settled in Grand Junction, CO, in 1984, where he spent an impactful 16 years as City Manager fostering relationships with staff, city council, and citizens. He championed transparency and sound fiscal planning and enhanced community resources. In 2000, the city commemorated him with Mark's Trail, a tribute to his long lasting commitment to public service and love of the outdoors. In retirement, Mark inspired others as a "Range Rider" mentor for city managers throughout the state and was honored with the International City Management Association's Lifetime Achievement Award.
With a propelling sense of adventure and impeccable internal compass, Mark completed all 54 of Colorado's fourteeners, earning a spot on the Colorado Mountain Club's 2001 completers list at #984. Deeply respectful of nature, he embodied the principles of "leave no trace." His adventurous spirit also shone through when he surprised Mary Ann with a boat one Mother's Day, leading to countless joyful memories at Lake Powell, where horseshoes became a favorite pastime—so much so that he and the family boat earned the affectionate title "Double Ringer."
Mark was a vibrant member of the fun-loving 'Gatsbys' social group and an active Rotarian. He found joy in hiking, climbing, skiing, tennis, and golfing. He was known for that twinkle in his eyes and the way he lit up a room with his laughter. He slept little, lived big, and wanted for not.
Mark was preceded in death by his parents, Marjorie and George Achen; his brother, Fred Achen; and his beloved and beautiful granddaughter, Sayler Mackenzie Corr. He is survived by his loving wife, Mary Ann Achen; daughters Wyndi Marie Achen and Kara Lynn Southall; grandchildren Siena and Evey Southall, and Marlo Corr; brother Patrick (Ginny) Achen; sisters Georgia Beth (Jerry) Nichols, Kerry Jo (Mike) Meadows, Gail Thomas, and Heather Lynn (Robert) Rossi; sister-in-law Donna Epstein; and nephews Shane Achen; Kane Thomas; RB Rossi; Taylor Percy; Jameson Achen; Adam Epstein, and nieces Shawna Clarke; Paris Achen; Bethany Achen; Ashley Laine Smith; Freddie Sayles Rossi; Karmen Thomas; Carly Epstein, and many great nieces and nephews.
Mark's life was one of adventure, joy, and devotion to family and community. He will forever walk beside us in spirit, and his legacy will continue to inspire us all. A memorial service will be held at the First Presbyterian Church on Saturday, October 12th, 2024 at 11:00am followed there by a reception and then burial at Orchard Mesa Cemetery. Visitation will be held at Callahan-Edfast Friday, October 11th, 2024 6:30pm to 8:00pm. Memorial donations can be made to GJ Rotary or Hopewest.
