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.

Angela Hu
Chief Operating Officer
Angela Hu is COO of Kilmann Diagnostics (KD) in Newport Coast, California. In 1985, at the age of 20, she graduated summa cum laude from Shanghai Jiao Tong University (Branch), China (later named the Shanghai University of Engineering Science) with a Bachelor of Science degree in electrical engineering. After researching and teaching in the area of automatic control systems at that same university, in 1985, she decided to establish her own company, Shanghai Changtong Consulting, which focused on educational exchange programs all across the world. Based on her marketing savvy and business expertise, she was appointed in 1998 as the Vice Chairman and President of Shanghai Airlines, Houston office, where she was in charge of the Sino-USA airlines operations, and where she arranged many trade missions between the U.S. and China.
After moving to Houston in 1999, Angela was elected to the position of Vice President of the US-China People’s Friendship Association, which was founded in 1974, well before the U.S. and China had established formal relations in 1979. Her performance in that position earned her considerable admiration and respect from both countries. As an indicator of her success, she received the highest honor and recognition as an Honorable Citizen of Texas from Governor Rick Perry in 2003.
During her work in Texas (until 2016), she held multiple titles in various organizations: she was the founding President of China General Chamber of Commerce at the USA Southern Region (CGCC) which includes members listed on the Fortune 500, such as the Sinopec Group and PetroChina. She also held the position of Vice President of East West Bank (Western region); the Chief U.S. Representative and Chief Representative of Shanghai Lonyer Fuels Co. Ltd.; and Senior Consultant in GlobalXLR. In subsequent years, inspired by the loss of her dear mother who suffered from cancer, she founded the Cancer Patients Platform with support of the National Foundation for Cancer Research. That platform offered second opinions on cancer diagnosis and treatments from the top scientists and researchers in the world. This startup had to be terminated prematurely, due to the COVID pandemic. In 2020, encouraged by some young college students who have passions in digital currency technology, she became seed investor and Co-founder of rssdao.cn.
Angela’s passion in working with Kilmann Diagnostics is based on a keen interest in not only workplace conflict (based on her extensive business experience), but she also has a deep interest in resolving political conflicts (given her extensive experience in China/U.S. relations). Angela is well aware that incidents of both organizational and global conflicts have surged significantly in recent years, which is why she is so passionate about helping people and nations transform their major conflicts into golden opportunities for learning, growth, and long-term success.
As KD’s COO, Angela uses her extensive business expertise and dedication to improve KD’s current operations, cultivate an engaged tech-savvy workforce, enhance KD’s customer experience, and make good use of her native Mandarin language and her intimate familiarity with Asian markets to expand KD’s reach into China, Japan, South Korea, Singapore, and other Asian countries.
