E.O. (Trey) Scott III

With a career spanning over 3 decades, Mr. Scott has worked in oil and gas since 1976, including summers on a drilling rig both onshore and in the Gulf of Mexico, between college semesters at Texas Tech University.

Mr. Scott is a Certified Professional Landman. In 1979, he went to work for an oil and gas lease broker in Corpus Christi, Texas as a field Landman. His duties consisted of mineral title research, oil and gas lease negotiations and title curative. In 1981, Mr. Scott opened his own office as an independent Landman, overseeing several lease brokers and successfully acquiring hundreds of oil and gas leases. His experience in the oil and gas industry includes an in-house position with a San Antonio based Exploration & Production Company where his duties included many aspects of oil and gas exploration, development and gas marketing.

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. Mr. Scott continues to be involved in all aspects of managing oil and gas royalty portfolios, including the development of databases and software for oil and gas management. Moreover, he has extensive experience utilizing Global Mapping System (GIS) and assists in litigation support including expert consulting and witness testimony.

Mr. Scott is a member of the Texas Land and Mineral Owner Association where he is currently serving on the Board of Directors, the San Antonio Association of Professional Landmen where he served as President and as Education Chairman, the American Association of Professional Landmen, and the South Texans’ Property Rights Association. He also served on Texas Railroad Commissioner David Porter’s Eagle Ford Task Force and has presented or presided at well over 60 educational presentations.

Brett Stinson

Mr. Stinson has worked in many diverse fields over his career providing solutions to businesses to help advance the level of technology and ability to perform the business objectives with software and architecture consulting. Some of the industries he has worked in include: Manufacturing, Energy, Oil and Gas, Telecommunications, Banking, Retail, Non-Profit and Technical Support.

Mr. Stinson began his career in 1990 as a school teacher and football coach in Central Texas, but quickly realized the computer industry, and specifically development of computer software, was his true passion.

Mr. Stinson began writing software in 1992 and he continually strives to provide the best possible solution to the current business need as well as a level of support and understanding that is unmatched by common development teams and industry standards.

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 developer.

In September 2013, Mr. Stinson moved into the role of Chief Operating Officer for the company in order to help manage and promote the growth of the company and has since also taken on Senior Mineral Manager duties for a limited number of clients.
