Our Team

Terence W. Newlin, CPA

Terry founded Miller • Newlin & Co. in 1986 with his long-time business associate and good friend, John Miller. Together, they brought a great wealth of client service expertise and business know-how to the Firm.

Terry and John started out in Southern California with a leading Big 5 accounting firm, over 30 years ago. Both ended up as executive officers in industry for many years after becoming audit managers with the Big 5. The interesting thing is that before leaving the Big 5, Terry had moved on to the Houston office of the Big 5 firm, while John stayed in California to help open the new San Diego office for the firm.

As fate would have it and in many ways by remarkable coincidence, after five years in different industries and different cities, Terry and John found themselves across the table at a Smith International management team meeting in Houston in the early ‘80s. Yes, they were both living in Houston, working for the same public oil service corporation.

After four years together at Smith International, where Terry and John teamed with some of the most forward thinking entrepreneurial leaders in the oil service industry to improve systems, reduce costs, and streamline cash flow domestically and internationally during the retrenchment of the oil service business, they started MN&Co. And the rest is history . . .

With a Big 5 firm for eight years, Terry was an audit manager working with manufacturing companies, service organizations, real estate developers, and agribusiness ventures. Terry was on the team that performed the first audit of the financial statements of King Ranch, that great Texas ranching and oil & gas institution in Kingsville, Texas.

That King Ranch audit led Terry to leave the Big 5 for the initial Chief Financial Officer position of Shelton Ranch Corporation in Kerrville, Texas. Shelton Ranch Corporation was founded by a major shareholder of King Ranch and a King Ranch family member. The new company had agribusiness activities throughout the U.S. and a significant and very valuable interest in producing oil and gas properties. Terry designed and implemented the company’s accounting systems and developed innovative management reporting processes that were a rarity for the industry at the time. Three years later, Terry had the opportunity to join Smith International, Inc., as CFO/VP Finance of its directional drilling division, which had worldwide oilfield service operations. He was responsible for the financial management of the very dynamic business, including the structuring of international drilling contracts as to foreign exchange and monetary repatriation matters.

Over the past 16 years, Terry and the MN&Co. team have contributed to the success of a wide variety of clients, whose business interests span many industries, by providing them with the absolutely essential grasp of their financial picture, allowing them the opportunity to focus their efforts on operations, to keep heading in the right direction.

Terry has been a member of the American Institute of CPAs for over twenty-five years. He is also a member of the Texas Society of CPAs, and a former Board member and Committee Chairman of that organization’s Houston Chapter. He has written and had published several articles in such publications as the Oil & Gas Journal, as well as the American Management Association’s member publication.
