About our Founder

Marty Petty, Founder and CEO of The MPetty Group, brings significant senior-level, management experience to her work. With 35-plus years of C-suite experience, she understands the challenges CEOs face. Collectively, her work encompasses all aspects of building high-performing and sustainable talent assets in organizations. In fact, this work has defined Marty’s career.

At USF Health in 2013, Marty was introduced to Dr. C. Stephen Byrum and the Hartman Value Profile/The Judgment Index.™ She realized this powerful tool would have been extremely valuable during her C-Suite tenures. With Steve as her mentor, Marty earned her Master Certification to administer the instrument. Today, she is one of fewer than 100 people worldwide qualified to do so.

Dr. C. Stephen Byrum has been recognized as the international authority on the The Judgment Index.™ A protege of Robert S. Hartman, PhD, he has given his primary attention to advancing the work of this unique tool’s creator for more than 45 years, and in a variety of organizational settings. He has developed numerous applications and interpretations under the brand, the Hartman Value Profile.

Dr. Byrum’s breadth and depth of knowledge, and expertise in applying the insights revealed in more than 70 scientific indicators, deepen the bench of the team for the benefit of our clients.


The late Dr. Robert Hartman (1913 - 1973), was the creator of the The Judgment Index.™ He believed a person’s values constituted a major motivational factor in the way their life was lived. Most significantly, he believed that values primarily manifested in the judgments, decisions, and choices we make about people and work are what drive our lives.

Having the capacity to make good judgments is an indispensable aspect of life and work. Without question, people of good judgment will always be a beneficial addition to any work environment, family role, and to any community.

Shortly after his sudden death in 1973, Dr. Hartman was nominated for the Nobel Peace Prize for his groundbreaking work that provides unique insights into how an individual’s value system shapes his or her judgments, now a five-decades-old instrument.
