After Ralph left UCLA, he immediately began his professional career as an Assistant Professor at the Katz School of Business, University of Pittsburgh. In 1991, the faculty awarded him the George H. Love Professorship of Organization and Management, which he held until 2002, when he relinquished his tenured faculty position. Instead of staying in Pittsburgh, Ralph moved to the West Coast, since he wanted to fulfill his California Dream, which eventually led to the creation of Kilmann Diagnostics.

Ralph has published more than twenty books and one hundred articles on such subjects as conflict management, organizational design, problem management, change management, and quantum organizations. In 2021, he published his LEGACY BOOK, which integrates everything he has created during the past five decades of his professional life: Creating a Quantum Organization: The Whys & Hows of Implementing Eight Tracks to Long-Term Success. Ralph is also the coauthor of more than ten assessment tools, including the Thomas-Kilmann Conflict Mode Instrument (TKI), the Kilmann-Saxton Culture-Gap® Survey, and the Kilmann Organizational Conflict Instrument (KOCI). In 2023, Ralph published his first book that focuses on the TKI assessment tool: Mastering the Thomas-Kilmann Instrument: Celebrating More Than 50 Years of Resolving All Kinds of Conflicts.
Since 1985, Ralph’s professional biography has been profiled in Who’s Who in the World. And then, in 2017, Marquis Who’s Who distinguished him as a “Lifetime Achiever” and featured his profile in Sciences.
