Meet the NTSI Team

Jeffrey M. Chase, PhD, Chairman

Jeffrey Chase founded NTSI in 1974 as a graduate student in order to gather research subjects for his subsequent papers on attitude’s effect on driver behavior. It is thanks to his efforts that NTSI, as an approved Sponsor, has been effectively reducing collisions and violations in New York state for over 30 years and for the nation for over 40 years.

Dr. Chase started out as a Firefighter and EMT in 1965. In this profession, he saw the carnage that follows negative driving behavior on our roadways. Seeing the havoc wrought by careless drivers, Dr. Chase sought to educate himself and find a better way to improve driver safety.

Dr. Chase began his academic career at West Valley College where he received a Business Administration degree in 1969. During this time, in addition to working as a first responder, Dr. Chase was a certified instructor for the American Red Cross Advanced First Aide Program actively conducting classes between 1965 through 1970. He then received his Fire Science Degree in 1972 and his Political Science Degree in 1974 from the San Jose State University.

Shortly thereafter in 1975, Dr. Chase was honored with a lifetime teaching credential in Public Safety and Accident Prevention including Driver Training and Education from the California Superintendent of Public Instruction. The following year, 1976, Dr. Chase received a Masters in Public Administration from San Jose State University and published his Doctoral Dissertation “Analysis of California Driver Behavior and the Need for Traffic Safety Education.” With his dissertation completed, Dr. Chase went on to expand NTSI operations and was officially awarded his PhD in Psychology in 1978 from Newport University.

As Dr. Chase spread his innovative curricula across the nation, he was appointed to the faculty of the National Judges College at the University of Nevada where he served from 1982 through 1987. In 1995 he was recognized by the World Safety Organization with the Concerned Citizen Award. In addition to these awards, he has also held membership in the American Association of Motor Vehicle Administrators, the American Society of Safety Engineers and the National Judges Association among others.

Over the last 40 years, Dr. Chase has dedicated himself to improving driver safety. In doing so, he has created a company to embody his goal of preventing collisions and violations in an effort to ultimately save lives. With Dr. Chase’s guidance, the following team has been selected to continue his efforts.

Mr. Irons received a Bachelor’s Degree in Behavioral Science from Eastern Washington University.

Since 1997, Mr. Irons has managed the development of some of the nation’s most innovative programs to promote individual safety. These educational programs are available around the United States, Canada, and Mexico, and include traffic citation dismissal courses, court-ordered defensive driving programs, novice driver programs, senior driver programs, road rage/aggressive driving programs, corporate safe driver programs, DUI screenings, theft education workshops, substance abuse programs, and civic responsibility programs.

Jill Sullivan, Vice President of Sales and Marketing

Jill Sullivan is the Vice President of Sales and Marketing for NTSI since 2009.
