Bill J. Bonnstetter
January 22, 1938 – June 2, 2016
After a battle with cancer, Bill J. Bonnstetter passed away June 2, 2016, surrounded by loving family and friends, who were by his side throughout his journey.
A true thought leader who was passionate about human behavior and an elevated understanding of how individuals think, behave and work, Bill J. Bonnstetter was determined to touch lives throughout the world with this knowledge.
Bill was the co-founder and chairman of the board of Target Training International, Ltd. (TTI) and TTI Success Insights, Ltd. based in Scottsdale. Established with his son, Dave, in 1984, TTI develops and markets research-based, validated assessments available in more than 90 countries and 40 languages. These tools help people understand and appreciate their uniqueness, then understand and appreciate others and find better ways to live, work and build relationships.
Born in Corwith, Iowa, to Opel Gregson Bonnstetter and Ernest Bonnstetter, Bill was raised on the farm and took an early interest in sports. He attended the Iowa State Teachers’ College, where he earned his bachelor’s degree in business with an emphasis in marketing in 1964, then immediately went on to earn a master’s degree in business education, in 1969, from the University of Northern Iowa.
Bill’s talents and experience were diverse: he was also a college professor, a police officer and served the U.S. military. He moved from Iowa to Scottsdale, Arizona, in 1988, where TTI became headquartered, but always supported his hometown community. Each year, he held gatherings in Scottsdale for his friends and family from Corwith.
Bill was a true trailblazer. Considered one of the pioneers in the assessment industry, he was the first to computerize the DISC (Dominance, Influence, Steadiness, Compliance) assessment and later making reports available via patented Internet Delivery Service ® (IDS). He was also the first to produce a computerized values assessment based on Eduard Spranger’s personality model. Bill applied for and was granted four U.S. patents. He was also a 2012 Edison Award nominee, which recognized his innovation and excellence in the development, marketing and launch of TTI’s products.
Bill felt driven to share his knowledge and experience with others. He was always happy to share his knowledge with a group of 10 or 10,000 and was an international speaker and the author of several books, including The Universal Language DISC, which has sold over 30,000 copies, If I Knew Then and Talent Unknown. His most recent research was published in Harvard Business Review, Fast Company, and Inc., as well as a host of other scholarly journals.
Bill’s passion was his work – and he continued to be highly involved in leading and driving innovation at TTI until the end of his life. With his brother Ron, Bill began conducting brain research five years ago, which validated with neurology his earlier social science findings.
Always driven by a desire to help others and to provide a human touch, Bill saw to it that a person always answered the phone at TTI and that TTI’s customer support was second to none. Ever generous to his clients and friends, Bill helped launch the careers of hundreds of highly successful business owners around the world and donated millions of assessments to organizations and non-profits. He always believed that self-awareness was a right and that the TTI tools should be made available to all who needed them.
He leaves behind his wife Karen Killoren; sons David of Scottsdale, Arizona and Matthew of Sedona, Arizona; two step children, Kellie Killoren of Phoenix and Jeffrey Killoren of Phoenix; two grandchildren, Alec Bonnstetter and Aftynn Bonnstetter; two step grand-daughters, Meagan Killoren and Tayler Killoren; two brothers James Bonnstetter of Milford, Iowa, and Ronald J. Bonnstetter of Scottsdale. He was preceded in death by his sister, JoAnn VandenBerge.
