Killam Oil Company

Killam Oil Company was formed to steward the Killam family's holdings after generations of activity in South Texas oil and gas. David Killam serves as managing partner and CEO. Cliffe Killam, David's son, leads Killam Development, the real estate arm. The firm concentrates on natural resources and real estate. It holds direct interests in South Texas oil and gas assets, Duval County Ranch, Killam Ortiz Ranch, Dana Ranch in Montana, and multiple industrial parks including Killam Industrial Park, Sharyland Business Park and Avila Industrial Park. Additional holdings include mixed-use projects in Laredo and Santa Teresa, New Mexico. All positions are executed as direct ownership or SPVs rather than fund commitments. The office maintains a small internal team and lists no additional locations beyond Laredo. David Killam belongs to the Young Presidents' Organization and All American Wildcatters. The family operates the Killam Family Foundation for philanthropic activities. Ownership remains within the Killam family with operating control retained inside the office rather than delegated to external managers or co-investors.
