Ellis Amdur received his BA in psychology from Yale University in 1974 and his MA in psychology from Seattle University in 1990. He is both a National Certified Counselor and a State Certified Child Mental Health Specialist. Since the late 1960s, Amdur trained in various martial arts systems, spending thirteen years studying in Japan. He is a recognized expert in classical and modern Japanese martial traditions and has authored three iconoclastic books as well as one instructional DVD on this subject. Since his return to America in 1988, Ellis Amdur has worked in the field of crisis intervention. He has developed a range of training and consultation services, as well as a unique style of assessment and psychotherapy. These are based on a combination of phenomenological psychology and the underlying philosophical premises of classical Japanese martial traditions. Amdur's professional philosophy can best be summed up in this idea: the development of an individual's integrity and dignity is the paramount virtue. This can only occur when people live courageously, regardless of the circumstances, and take responsibility for their roles in making the changes they desire. Ellis Amdur is a dynamic public speaker and trainer who presents his work throughout the United States and internationally. He is noted for his sometimes outrageous humor as well as his profound breadth of knowledge. His vivid descriptions of aggressive and mentally ill people and his true-to-life role playing of the behaviors in question give participants an almost firsthand experience of facing the real individuals in question. His books are considered unique in that he uses his own experiences, often hair-raising or outrageous, as illustrations of the principles about which he writes, but it is also backed by solid research, and boots-on-the-ground experience.
