Our Team

Like all companies, we are a collection of disparate personalities and styles. We’d like to give you an idea of who we are. By “taking our own medicine” so to speak, we are better able to address the issues that are faced by our clients.

Unlike large consulting firms stocked with freshly minted MBAs, our staff has the benefit of real-world experience; successfully analyzing, implementing and delivering innovative, proven approaches to change management and HR transformation.

Jerry Brown, Ph.D., TFd, Certified TDF Trainer
Jerry was in on the early days of the formation of TDf. In his thirty year career he has used the TDf in a variety of settings. As a Licensed Professional Clinical Counselor and a certified Pastoral Counselor working with individuals, couples and families, he found the TDf to be the most effective of the several personality instruments on the market. In teaching a Personal and Professional Growth course for graduate students, TDf served as the tool to discovering self-identity, understanding others and developing growth strategies in every aspect of their lives. When Jerry served as the manager of a hospital-based behavioral health clinic, he trained the entire staff of psychiatrists, psychologists, therapists and support staff in the TDf. In more recent years he has transitioned into conducting TDF workshops and consulting with businesses such as hospitals, leadership groups, CPA firms, retail sales and even using horses to demonstrate the practical applications of TDf. In addition, Dr. Brown has written a book on team-building and several articles on self- awareness, management, leadership and communications. He also trains psychotherapists in the use of the TDf. Dr. Brown has degrees from Baylor University and Southwest Baptist Theological Seminary. For more information visit Dr. Brown's website drjerrybrowntdf.com.
