THE OFFICIAL HOME OF THE
GREELEY WRANGLERS
Meet Your Team Owners
The Wranglers are the latest expansion team in the Front Range League, and the team is founded by Mayra and Chuck Heeman. The Heemans also own and operate the Johnstown Outlaws of the FRL, and Chuck Heeman is the President of the Front Range League.
The Heemans have eyed Greeley as a great location for the team and league, and when the opportunity came to relocate to Butch Butler Field and Greeley, Chuck and Mayra were thrilled to become members of the Greeley community.
Mayra and Chuck look forward to becoming part of the community and seeing you all at the ballpark!
Chuck Heeman, Managing Partner
After working for more than 35 years in professional sports, Chuck Heeman, along with his wife Mayra, founded the Wranglers in the fall of 2025, leading up to our inaugural 2026 season. Following a year in Ft. Morgan, the Wranglers relocated to Greeley, Colorado for the 2027 season.
Chuck has served as General Manager for four professional baseball teams as well serving as the founding General Manager with two Oregon-based summer collegiate baseball teams, the Klamath Falls Gems and Medford Rogues. Chuck also served four years as Operations Manager with the Arizona Diamondbacks. His sports experience also includes three years with the Cleveland Indians and Cincinnati Reds at their Goodyear, Arizona Spring Training complex immediately prior to purchasing the Western Nebraska Pioneers franchise in 2017. Following nine years in Nebraska, Chuck and Mayra made the move to Greeley in advance of the 2027 season.
Chuck, age 67 and getting too old for all this nonsense, is also a disabled veteran of the U. S. Air Force, a 13-year former U.S. Postal Service worker and a graduate of Arizona State University. Born in Detroit, Michigan, Chuck grew up in Cuyahoga Falls, Ohio. He is married to Mayra Heeman. The couple has four children and six grandchildren and resides in Greeley, Colorado.
Mayra Heeman, Managing Partner
Mayra, the retired mother of four and grandmother of six, volunteers her spare time to help the Wranglers in a number of ways. She recruits and works with host families and helps with business operations. Following a heart attack, quintuple bypass and stroke in the fall of 2018, Mayra has cut back on her baseball duties and is restricted by management (her daughter) from doing too much. Fans and friends are encouraged to tell Mayra to slow down!
Due to past... let's say... "incidents"... Mayra is not allowed to sit and watch games in which she is not working (she gets a little intense - some stories there if you'd like to hear). However, Mayra is always ready with a smile and a hug at Wranglers games and loves to spend time with the fans.
Mayra served for five years as a volunteer with the Klamath Falls Gems and Medford Rogues (both in Oregon) where her husband served as General Manager. Prior to retirement and getting sucked into the baseball world, Mayra worked in the legal field as a litigating paralegal for law firms in California and Arizona.
A native of Mexico, Mayra came to the United States at age nine and grew up in Southern California. Mayra and Chuck Heeman were married in 2008 and moved to Gering, Nebraska in August 2017. The couple relocated to Greeley, Colorado in September 2026 to operate the Wranglers and Johnstown Outlaws.
INTERNS AND GAME DAY
The Wranglers are proud to partner with the University of Northern Colorado's Sports Administration program to provide interns, game day staff and guidance. Our mission is to train UNC's Sports Administration students using real-life situations and events to provide experience as these students move into the sports world. We'll share the biographies and personalities of these invaluable members of the Wranglers operation as we bring them aboard!
