John Leslie Mammen was born October 15, 1944 to Johnny Herman "JH" and Lorene Mammen in Dallas, Texas. He lived in Irving, Texas until moving to Haslet, Texas with wife Theresa in 2000.
John attended Irving High School as a member of the class of 1963 and studied at the University of Texas at Arlington.
John served in the US Army and the US Army Reserves from 1966 to 1972 in a combat engineering unit, and was a decorated sharpshooter.
In 1969, John married Theresa Gilmore of Dallas Texas, and they celebrated their 48th anniversary on January 25, 2017. John and Theresa raised two sons, Chris and Robert.
John's parents founded the family business, Mammen Glass and Mirror, in 1956, where John worked with them from age twelve until assuming leadership of the company as President in 1980, and then retiring in 2012.
With his brother Jim, John grew and expanded the business from auto glass to include residential and commercial glazing. His sons Chris and Robert grew up working in the family business with their Dad through high school. Robert returned to help open and run the new Austin branch after college in 1997 and 1998. John was rejoined in the family business by son Chris in 1993. John, Jim and Chris added glass fabrication equipment and grew the business rapidly. Under its new name, M3 Glass Technologies, the company won the Inc 5000 award for fastest-growing businesses in America five times between 2007 and 2013. The company was named Small Business of the Year for the South Central region for three years in a row by the U.S. Chamber of Commerce in 2007, 2008, and 2009.
John served on the board of directors for the National Glass Association for six years. He also was a founding board member of the Metroplex Glass Dealers Association. In 2015, John won the Johnny Lamb Award for dedicated service to the glass industry. John was known and respected throughout both the local business community and the national glass industry. He was an active member of the Irving Ambucs Club for many years.
John loved to travel for both business and pleasure. He loved cruising with his wife Theresa, especially in the Carribbean and tropics. They also made many other trips together, including Israel, London, the Panama Canal, and Alaska. John and Theresa enjoyed visiting Ruidoso, New Mexico together and made the trip many times. In 1994 John and son Chris traveled to Russia together, fulfilling a lifelong desire. He enjoyed traveling for business as well, making trips to Italy. Germany, The Netherlands, Spain, Australia, China and Israel.
John was a Christian and a dedicated husband, father, and grandfather. With his sons, John participated in soccer, basketball, karate, bmx, Indian Guides, Cub Scouts, and Boy Scouts. Grandchildren Jon, Jonah, and Jadon were a great source of joy and pride for John. He loved babysitting and attending soccer and hockey games with them, and he recently got to fly with his pilot grandson, Jon. He cherished every moment spent with Jadon, Jonah, and Jon.
John held various church leadership positions during his life. He participated in Bible Study Fellowship for many years and was a discussion leader as well. He was sustained by his faith and his family throughout his life and his battle with cancer. John was the spiritual leader of his family, influencing his children and grandchildren to follow his example.
In the summer of 1993, John was diagnosed with prostate cancer, and for the next 24 years he regularly outlived the estimations of his doctors.
John is survived by wife Theresa; son Chris and daughter-in-law Jennifer of Grapevine, Texas; son Robert of Austin, Texas; grandsons Jon, Jonah, and Jadon; and brother Jim and his wife Ann of Roanoke, Texas.

Mr Mammen was one of my favorite patients. He always had something positive to say and gave me a smile.
He was one of those special people you meet in life and immediately like.
He will be missed by all who knew him.

Condolences, Theresa and family. I shall always remember John, the brother I never had growing up. We met in 5th grade and started a string of memories for me. Playing around cutting glass in the shop, working on our cars, helping John set a plate glass window in a store in Preston Center, the trip to California in his new Ford after graduating high school, the trip to Florida the following summer in my old Corvette, helping him set poles for a barn at the family farm in Hawkins, cruising the streets on Friday and Saturday nights, and so much more. You will be missed, John.

Sending prayers and condolences to the Mammen family in this time. I will always remember Mr. Mammen as a kind man. Growing up in Irving he was more than just "The Glass Man"... he opened his home to many young budding artists to provide a haven for practice and community. Big hug especially to Chris and his family.

I am so sorry for your loss and will be praying for you.
The Blues Brothers Photo in the photo gallery reminded me that John and I attended the '62 Junior prom wearing black Bermuda shorts,long black socks white dress shirts & a tie. I think it was his idea and our dates were not happy. I will see him again and will find out who's idea it was but we had a laugh.
Bless you. Bob and Laura Wallace

We have valued you and Johns' friendship for many years and will definitely miss hanging out with you both. There are no words that could possibly do justice to express what you need to hear at this very time. Know that we live close and are here to listen to anything you want to say. It is a comfort to know that those we lose live on in our hearts and minds forever. May your beautiful memories and love remain and live on for many years to come.
