For over 70 years, Nadel and Gussman has focused on family, ethical transactions, and modern oil innovations. We are a fourth generation family-owned, independent oil and gas production and exploration company headquartered in Tulsa, Oklahoma. Isadore Nadel came to Oklahoma in 1919 to open a grocery store and would later go on to lead one of the largest oil producing companies in both Oklahoma and Kansas and made significant contributions to the modern oil industry and community of Tulsa. Herb Gussman, Nadel’s son-in-law, joined the company in 1935 to form Nadel and Gussman.
Stephen Heyman and James Adelson joined the leadership team in 1965 and 1986, respectively, and still guide Nadel and Gussman today. Under their leadership, Nadel and Gussman grew aggressively into other basins in the United States by the 1990s.
Today, we have operations across the United States, including Oklahoma, Kansas, Texas, Louisiana, and New Mexico. We focus on drilling and purchase production drawn from our own resources as well as expanding into other types of ventures both conventional and unconventional.
