In 2005, after a highly successful stint as a company landman specializing in Lease Acquisition, Dan Sullivan decided to embark on a journey to provide the energy industry with superior, professional land services.  He also enlisted Brad Mason, who joined Sullivan Land with thirty years of landman experience and is one of the best title researchers in the business.  Their expertise and integrity have made Sullivan Land Resources one of the top brokerage firms in Oklahoma.  Sullivan Land has experience throughout the United States and continues to adapt to an ever-changing industry in order to produce results for our clients.
