Alan Wayne Geistman

1949 - 2025

Alan Wayne Geistman died August 28, 2025, at the age of 75 from complications related to gastric cancer. A true and proud Texan, Alan was born October 19, 1949, in Harlingen, Cameron County, Texas to Julius Lehman (J.L.) Geistman and Inez Lollar Geistman. He spent the first five years of his life on the family farm just west of Rio Hondo, Texas. The family moved to Lubbock, where Alan spent his early childhood. They relocated in 1959 to Levelland to be closer to the family farming interests, and Alan graduated high school with the class of 1968. Alan loved nature, played sports (football and baseball), and played in the band.

Deciding not to stay in the South Plains, Alan followed his sister Gerry to North Texas State University (now UNT - University of North Texas), where he focused his studies on math, chemistry, and biological sciences. He was active in his fraternity, Sigma Phi Epsilon (Alpha Kappa pledge class), and many campus activities: Talons (spirit), student senator, student representative to the faculty athletic committee, and intramural sports. Alan transferred to the University of Texas in 1972 to attend pharmacy school. At UT, Alan was also active in intramural sports. He graduated in 1974 with a BS in Secondary Education.

Alan's post-university life began at the Texas House of Representatives, followed by working for the Texas Department of Human Services. Ultimately, he entered a career in the national commercial and multifamily real estate development industry. He began in development with Dick Hardin, a major commercial developer based in Austin, before joining NPC in Austin. Later he worked for noted multifamily and commercial developers Jerry Stone of The Duke Companies and Walter Embrey of Embrey Partners of San Antonio.

Alan and family moved to Llano, Texas to raise Natalie in a more grounded environment with a public school district that was exemplary rated. Living in Llano was one of Alan's most joyous times. Outside of work, Alan was active on community service committees, school boards (serving as president of the Llano ISD School Board), church committees, and other activities. He always felt strongly that education was the key to everyone's future.

Alan had an unshakable faith in God and His son Jesus Christ. He was active in the life of the churches he attended over his life, teaching Sunday School, building housing in Mexico for missionary retreats, and serving on churches' finance committees and foundation boards. Alan enjoyed a blessed life, continuing to love and be amazed by nature. He was an avid sports fan (both playing and watching), and enjoyed travelling and being a family man.

Alan was always so proud of his family and loved them unconditionally. Alan is survived by his amazing wife, Jan Lehman Geistman (he and Jan celebrated their 42nd anniversary one month prior to his death); his beloved and talented daughter, Natalie Lehman Geistman (he is so proud of his Trinity Grad); his sister, Gerry G. Woods and his brother-in-law and "brother," Dale J. Woods. He is also survived by his famous wonder-dog, Friar Tuck, and grand-dog, Alfred.

Alan had so many special friends and people in his life and wants to thank them for their long-standing love and support - Jan's family, great neighbors, and Bible study group. He also wants to thank his care team at MD Anderson (especially Dr. Blum-Murphy), Hospice Austin, and all of the caregivers and relatives involved in his final journey.
