Core Faculty, Distinguished Service Professor
Founder, Adler University Harold & Birdie Mosak Library

I am proud to say that I am one of the founders of Adler University. With my mentor, Rudolf Dreikurs, and colleagues Bernard Shulman and Robert Powers, we began in 1952 by framing our goals to reflect the work of Alfred Adler. Decades later, my personal mission continues to be to ensure that Adlerian concepts and practice remain central to psychological theory and therapy. Our commitment then and now has resulted in a rich, worldwide network of former students and professionals who embrace Adlerian practice. Seventy years after Adler’s death, his approach is as strong as ever.

Some of my fondest memories surround working with my wife, Birdie, to fulfill this vision. Over the years, we’ve created an extended family by connecting with hundreds of students and colleagues. There were times we provided meals and housing to students in need. There were summers with students in our home, with Birdie sometimes cooking for our “family” of twenty. We provided whatever students needed, and we’ve been repaid with the riches of their unending dedication. Birdie and I also worked on the comprehensive Bibliography for Adlerian Psychology, an effort of which I am immensely proud.

I am happy to say that after teaching for over sixty years at more than seventy institutions, I continue to enjoy my life’s work. In 1952 Birdie and I founded Adler University's Harold & Birdie Mosak Library, which continues advancing Adlerian learning today. Currently, I teach Adlerian theory and methods as well as clinical seminars; my interests are in the role of the spiritual in psychotherapy, multiple psychotherapy, and group and couples therapy.

As for the future of the University, I am especially confident when I see the work of our wonderful students and faculty. Their commitment to promoting social interest and focusing on communities as a strategy for mental health is the foundation for Adler University’s present-day commitment to social justice. The future is indeed bright.
