In Memoriam: Machen, Glace and Rehmann

TWA mourns the recent passing of three TWA leaders. Their vision, leadership, and experience helped steer TWA through its years.  Those of us who have been fortunate enough to know and work with them have lost a dear friend and inspiring mentors. 


Gary Machen, TWA Co-Founder

Gary Lynn Machen, 75, of Pearsall, Texas was born in Robstown, Texas.  Gary was a long-time resident of Frio County.  He was a farmer, rancher, and avid hunter.  Gary was on the All American Team for Competition Shooting and stayed in the top 5 in the United States for 10 consecutive years.  

Gary was very instrumental as one of the founding members of the Texas Wildlife Association. He sat on many boards and committees helping set guidelines and rules for the hunting and deer industry, as well as protecting property rights for landowners. In 2005, he brought the Los Cazadores contest to Frio County and helped build the Los Cazadores store and restaurant.

Gary was married to the love of his life, Barbara Machen, for 54 years.  They made their home at the O.W. Machen Ranch where Gary became one of the top whitetail deer breeders in Texas.  He loved watching old westerns and his favorite sport, baseball, with his two girls, Hallie and Madison Dugosh.  They all spent countless hours hunting, playing cards, and laughing. He is survived by his wife, Barbara Machen, Justin and Amy Dugosh, and daughters Hallie and Madison. 


Chaz Glace, TWA Board Member

Chaz Glace, philanthropist, successful businessman, beloved father, and grandfather, and pillar of the Round Rock community passed away peacefully in his home.

Charles Jeffery Glace was born in Buffalo, New York, and spent his early years in New York and Ohio.  In the mid-’70s, he relocated to Central Texas to manage a construction job for his employer.  While here, he made a decision that would change his life, and the lives of so many around him.  His dream of having his own construction company met opportunity, and, in 1979, Chasco Constructors became a reality.  With that, the legend of Chaz was born. 

What started as a 4-man construction crew was transformed into a 300-man success story.  From extremely humble beginnings, his hard work, grit, and determination were rewarded.  He was not from Texas, but he became a Texan through and through.  In the beginning, it was a black hat, white shirt, and starched jeans – always with exotic skinned cowboy boots.  Later, it was shorts and sandals.  But it was always 100% Chaz. 

After guiding Chasco Constructors for 36 years, he handed the reins to his two sons, Chuck and Tony. After Chasco and his family, Chaz’s greatest passion was helping children.  He gave generously of his time and treasures.  The Williamson County YMCA was near and dear to him and he was especially proud to have the Chasco Family YMCA named in his honor. 

He was a long-time supporter of the YMCA, C-5, Play for All Abilities Park and Boy Scouts & Girl Scouts of America, and a former board member of the Texas Wildlife Association.  He was also active with Families of Fallen Soldiers and the Round Rock Police Olympics, just to name a few.  Chaz supported so many of the needs of the community, quietly and without fanfare. 

In 2012, he was named philanthropist of the year by the Greater Round Rock Community Foundation. He loved his family, Texas Longhorn football, cars, and golf.  His passions included American-made hot rods, his motor Coach group, NASCAR races, and car shows. 

Chaz is survived by sons Chuck Glace and his fiancé, Kristi Mabry, Tony Glace and his wife Leslie, and his six grandchildren, Preston, Karlie, and Abbey Glace, as well as Hudson, Paige, and Mandy Glace.  He is also survived by his sisters, Anita Palmieri and Roberta Barb, and her husband Chris.

Among the many awards, he was honored with were the Texas Outdoorsman of the Year, Texas A&M University Construction Science Outstanding Alumni Award, and nominee for Entrepreneur of the year.
