The Wren Effect
A Legacy Being Replicated Across Generations
The Wren Effect is a phenomenon experienced firsthand by countless student-athletes over the past 30 years. It’s the impact that associate professor and former coach Kirk Wren had on them while at Ottawa University that is now rippling through their adult lives and careers to impact those they teach, coach, and serve.
Wren started at OU as an exercise science instructor and coached both men’s and women’s cross country and track and field for 22 of his 30 years. After leaving the track in 2018, he continued as associate professor of exercise science and sports leadership and currently serves as lead faculty for physical education. One of his greatest honors was a stint as co-athletic director with his mentor, the late Coach Andy Carrier. Wren was inducted into OU’s BAHOF in 2021.
The Wren Effect showed up early in his career as a recruiter and a coach. “I went to 100 counties in Kansas to find those diamonds in the rough and recruit them,” he said. Beyond how fast they were or how far they could throw, Wren was looking for the athlete that had good character. “I recruited state champions, sure, but it was more important to have that student that showed up on time, worked hard, had a good attitude, respected his team, and made OU look good.”
The recruits soon learned that Wren was only looking for what he possessed himself and gave back to them twice over. Whether coaching them in the classroom or on the field, he gave them A+ material to help then become A+ individuals. He used his quirkiness to impart knowledge, provided unique travel opportunities, challenged their abilities and conceptions, and helped them through life’s ups and downs. Along with wife Annette and two sons Nathaniel and Jonathan, Wren supported the students every step of the way by sharing the family’s farm life, as well as feeding and housing them to give students a home away from home. All to make them better athletes and better people.
“Taking a kid who can’t perform to one who excels is addicting,” says Wren. And the student athletes exceled for one simple reason – the person was more important to Wren than the performance. Once the students knew that, they gave him everything they had.
The Wren Effect is now rippling through new generations of students and athletes across the country because of those Wren has impacted at OU.
Justin Garrard ‘09 is paying it forward as the executive director of Adam’s Camp in Colorado, where they “empower individuals with intellectual and developmental disabilities through transformative camp experiences.”
“Great coaches don't just develop athletes, they develop people,” shared Garrard. “I had the privilege of being coached by Coach Wren from 2005-09 into an All-American, then I coached alongside him from 2010-12. That led me to inspire many other young men and women at other coaching stops, including William Jewell College (’12-’15), University of Pennsylvania (’15-’16), Florida State University (’16-’18), and recently Valor Christian High School (’24-’26). Thanks to his passion, I am still pursuing the sport, having just fallen short of the 2024 Olympic Trials for the Marathon and starting my Master’s career next year.”
Not surprisingly, the Wren Effect has now created the Garrard Effect on youth like Griffin Mazesk, one of Garrard’s former athletes. “Coach Garrard is more like a father than a coach,” he intimated. “He goes far beyond the workouts and seeks to understand each person as a child of God. When I was going through a rough time, he instantly sensed my pain and took time out of his practice to walk with me. That type of dedication is innate. He has not only made me a better athlete, but a better man of God. When someone motivates you to change who you are, you know they are special.”
Jeo Mendez ‘15 is another who experienced the Wren Effect. He is the director of vocational services at Ascendigo Autism Services, a non-profit in Carbondale, Colorado. “Coach Wren is one of the top 2-3 most influential people in my life,” recognized Mendez. “He took a kid from Rifle, Colorado, who didn’t have a lot of good male role models, and was interested more in me than my running. He cared - that’s what stuck with me. He taught me to be a leader and how to build others up. I would run through a brick wall for Coach Wren.”
Mendez went on to teach elementary school in Rifle, Colorado, for a year and high school in California for a couple of years, producing an athlete who holds the 800-meter record and another who won a CIF championship. But it is in his current role that the Wren Effect has glaringly become the Mendez Effect. Upon leaving the program, staff member Liam M. wrote, “You have truly been an amazing mentor, boss, and model for professionalism and advocacy. Being able to reach the professional heights that I have is far more of a testament to your ability than to mine. I wouldn't be anywhere near where I am now if not for your leadership and support.”
Even back in the 90’s, the Wren Effect was in full swing. “I was a father when I met Coach Wren,” said Robert Johnson ’98, “and I didn’t have a clue what that meant. Having a Coach who made sacrifices, held me accountable, encouraged me to work hard, and stood by my side through successes and failures gave me a sense of what my responsibilities as a parent should be.”
Which means that the Wren Effect began impacting the second generation of Johnsons while Robert was still at OU. Inspired by attending practices, daughter Clarissa went on to a decorated track and field and cross country career, both in high school and college, while son Dayvin earned all-conference recognition in baseball and was a starter throughout college. “The best part is that Coach Wren has been a huge supporter of my children throughout all the phases of their lives, even until this day,” said Johnson.
Johnson also served as Coach Wren’s assistant for nearly nine years. “Together we continued his legacy of giving student athletes unforgettable experiences and bringing out the best in them. I’d like to believe that I left a legacy of my own with those student athletes. Several are now coaches themselves.” The Johnson Effect. After graduating from OU, Johnson’s Effect continued when he joined the Johnson County (KS) Department of Corrections, where he currently serves as the Disproportionate Minority Contact Coordinator.
These are only three of many, many more who are better people today because of the Wren Effect on their lives. Perhaps their experiences can be summed up in the words of Janelle Bailey ‘12, who wrote Wren a note for Father’s Day.
“I just want to express how significant it was to have you as a coach for all of us college kids,” she shared. “We weren’t like a family per se, but you were in verity a paternal figure for many of us. You had true concern for our health and growth. You are an admirable man - your lifestyle, your energy, and your earnest manliness in running at your responsibilities.
Keep it up, Kirk Wren.”
