Glenn George Mortimer III, passed away at his home in San Antonio, TX at the age of 70 on August 1st, 2024 after a five year struggle with cancer surrounded by family and friends. Glenn battled the cancer with the same spirit in which he lived his life, with gratitude, humor, and faith. Glenn was born in San Antonio, Texas to Glenn George Mortimer Jr. and Elizabeth “Betty” Dorchester Mortimer on April 13th, 1954. He attended Alamo Heights High School where he proudly drove a Dodge Super Bee. Glenn graduated in 1972 and went on to attend The University of Texas at Austin where he was treasurer of Phi Gamma Delta Fraternity and majored in Finance. He was a devoted Longhorn his whole life and continued the strong friendships he built as a young man. Glenn’s pursuit of a Master’s in Business was interrupted when his father suffered a stroke, and Glenn returned to San Antonio to join the family oil and gas business. Glenn remained in the industry for the rest of his life where he may have been the most honest oil and gas man in the game. Glenn was a devoted husband and father. He met Betsy Halpin in 1979 at a mutual friend’s wedding where they stayed up all night at Mi Tierras and each had to figure out the other’s name the next morning. The third time Betsy proposed, he finally got the hint and asked her himself. The couple married on October 30, 1982 and their 42 year marriage continues to be inspirational to all who know them. The couple settled in San Antonio and had two children; Callie Mortimer Mayo in 1985 and Glenn George Mortimer IV in 1988. Glenn’s favorite pastimes were hunting at the family ranch in Harper, Texas and fly fishing at his favorite place on earth, the 4UR Ranch in Creede, Colorado. He instilled a deep love of both these places and pastimes in his children and grandchildren. Called “Father Mortimer” by many, he demonstrated his strong belief in the power of prayer as a young man and was often sought after to deliver the opening prayer at various functions, a job he excelled at. His wonderful prayers were the preamble to many an event. Glenn and Betsy were members of Christ Episcopal Church where he continued to develop his deep faith and served as a healing minister. Glenn was always generous with his time and was active in many social organizations. He was a member of the Texas Cavaliers and served as King Antonio LXXVIII, a member of the Order of the Alamo and Lord High Chamberlain, and a Past-President of the German Club. Glenn also devoted time to the Sunshine Cottage School For Deaf Children as a board member, going on to become Board Chair, an oil and gas investment consultant, and a fixture on the finance committee. In addition, he often volunteered at the school directly, enjoying his interaction with the students. He also helped grow the endowment of the Auditory Learning Foundation as one of their board members. Glenn is preceded in death by his parents Glenn George Mortimer Jr. and Elizabeth Dorchester Mortimer. Glenn is also greeted in Heaven by his dear friends Edward Carl Hegler III, Thomas Pace Mueller, and Kimberly Alan Ballantyne. Glenn is survived by his wife, Betsy Halpin Mortimer, his daughter Callie Mortimer Mayo, her husband Wesley Creamer Mayo, and their children Wesley Cade Mayo and Clara Adele Mayo, Glenn’s son Glenn George Mortimer IV and his wife Amy Kimm Mortimer, his sister Mary Mortimer Campbell and her husband Charles Harvey Campbell Sr., his sister Anne Mortimer Ballantyne and her husband Stephen Patrick Ballantyne Sr., his brother-in-law Robert Thornbury Halpin Jr. and his wife Mollie Loftis Halpin, his sister-in-law Terry Halpin and her husband John Hadden Halpin III, and all his beloved nieces and nephews. Glenn is also survived by Jane Ballantyne Hegeler, Mary Kennedy Ballantyne, and their children who, while not his family by blood, were loved as sisters, nieces, and nephews. He will be deeply missed by his many family and friends who knew him as a person who had never met a stranger, always had a great story to tell, and could be counted upon to fill up any space with his humor and warmth. Services will be held at 1 PM, Thursday, August 8, 2024 Christ Episcopal Church, 510 Belknap Pl, San Antonio, TX 78212. In lieu of flowers, donations may be made to: The Texas Cavaliers Charitable Foundation, 909 NE Loop 410, Suite 903, San Antonio, Texas 78209.
