After his time on the industry side of oil and gas, in 1995, Mr. Scott began an association with a local Oil & Gas Mineral Company where he successfully acquired mineral and royalty interest in several hundred producing oil and gas wells across the United States.

Subsequently, Mr. Scott started adding to his client list several South Texas ranches, where his responsibilities include overseeing and managing all aspects of mineral and royalty ownership such as negotiations, lease compliance, royalty audits, surface operations from drilling locations, pipelines, surface facilities, remediation and environmental issues.

In September of 2005, at the request of some key clients, Mr. Scott expanded his services by founding Trinity Mineral Management, LTD. (Trinity), where he is the Managing Partner. Trinity currently serves over 100 clients whose ownership spans over 1,000,000 acres of land.

In 2000, while working as a consultant in the greater Dallas area, Mr. Stinson started his own software company and began to consult for small businesses. His relationship with Mr. Scott started around that time, when he was recruited to make changes to a program called LandTracker, and has since continued as they have collaborated on many software projects over the years.

In early 2013, Trinity’s growth and need for software solutions allowed Mr. Stinson the opportunity to become a full-time employee of Trinity, where he is now the in-house software developer, Senior Mineral Manager, and the Chief Operating Officer.

Since joining the team at Trinity, Mr. Stinson has developed software and data solutions which provide clients with the ability to analyze and compare diverse data sets for the purpose of auditing oil & gas leases.
