DES MOINES, Iowa, August 15, 2023 — Turner Construction Company executives Barry Determan and Zach Loy will serve as the community volunteer co-chairs for the American Heart Association’s 2023-24 Heart Challenge.

Both Determan and Loy are part of Turner Construction’s Iowa Business Unit. Determan is a construction executive and Loy is vice president and general manager. Having participated in past events from the American Heart Association, devoted to a world of healthier lives for all, the duo will elevate their participation as co-chairs.

“Heart disease and stroke touch the lives of each and every one of us,” said Loy, a Turner employee for more than 15 years. “With the appropriate support for research, training, outreach and other key initiatives, we can positively impact outcomes for loved ones and future generations.”

The Heart Challenge is a suite of initiatives from the American Heart Association designed to help companies and individuals positively impact the health and well-being of Central Iowans through campaigns like CycleNation, Heart Walk and Hard Hats with Heart.

“At Turner, our team of over 300 local, Iowa-based employees are committed to making a difference in our community,” said Determan, who started his career with Turner 20 years ago. “I look forward to rallying a group of outstanding professionals to support a great cause and make this year’s Heart Challenge campaign one to remember.”

Central Iowa CycleNation is a high-energy, stationary cycling event scheduled to take place Thursday, Oct. 5, 2023 at Cowles Commons in downtown Des Moines. The Central Iowa Heart Walk is a 1- or 3-mile group walk to boost physical and mental health scheduled for Saturday, May 18, 2024.
