“I’ve done a lot of personal therapy over the years and I rank my experience with Bill as the best.”

Improving Lives In the Bay Area for Over 40 Years!

For over 40 years, The Berkeley Group and Family Therapy Institute has been a catalyst for change in the lives of thousands of Bay Area individuals.

The institute was co-created by Bill Roller, LMFT and Vivian Nelson, LMFT, internationally recognized leaders in group, individual, couples and family therapy. Bill is currently conducting all family therapy, couple therapy, and individual therapy for the Institute.


“I have seen Dr. Bill Roller for several months, and have become much more self-aware and in tune with my emotions than I have in my entire life. He has helped me tremendously through difficult life experiences, as well as helped me develop my own sense of what is the best way not only to navigate them – but to grow with them and grow through them. Now more than ever I’m able to see certain experiences in my life as part of a bigger picture that make up parts of who I am, and that I am completely able and entitled to change them if I see fit.

My experiences with Dr. Roller have shown me that while he brings immense expertise and wisdom to the table, true change begins with each of us and often with the invaluable help of an excellent therapist. Dr. Roller’s compassion, understanding and guidance have led me to finding my own voice, for which I will always be thankful to him for.”

We Have a Special Expertise in Group Therapy

The role of an expert is often misconstrued as one of perfection. In truth, the role of an expert means not just having a firm grasp of what is known in a particular field, it means knowing the gaps in knowledge and the directions of research that must be followed to fill those gaps. It means the discovery of new theories and methods of how these theories can be applied.

Our expertise in group therapy and group process lies precisely in this: Our research has specifically explored how groups develop, how a task leader and other leadership roles facilitate that development, and how a group leader must behave in order to confront aggressive scapegoating that will threaten the life of the group and its members. These are all cutting edge investigations in our field.

We’re at the Forefront of Group Process Research

Bill and Vivian have conducted clinical research in group therapy and group process (see The Promise of Group Therapy) and collaborated in the experimental study of what conditions allow people to act courageously in the defense of ethical principles or people in need of protection (see Group Dynamics and the New Heroism.)

It’s no wonder that other therapists come here to learn from us.  

“Bill Roller is a kind, sympathetic, caring and highly skilled professional. He is very empathetic and has helped me through depression, physical illness, and the difficulties of ordinary living.”

Our Non-Profit Public Interest Work

In addition to their clinical practice, Bill and Vivian direct the Berkeley Group Education Foundation, a nonprofit organization that serves the public interest and the common good by creating seminars and professional trainings, and producing educational videos for a wide range of audiences.

Most recently, the Berkeley Group Education Foundation has produced and sponsored national and international Symposia at clinical conferences and law schools in order to address the ethical issues that arise for both clinicians and lawyers as they confront and condemn the practice of torture as a policy of the state.

Public Address to Mental Health Clinicians in the People’s Republic of China

by Bill Roller, October 1, 2021

We just saw the collapse of a 20 year U.S. military crusade in Afghanistan to remake in our image an ancient culture we could neither comprehend nor deeply respect.  Mental health clinicians and group and family therapists could have shortened that war had we exercised our moral authority and publicly called out the damage being done to our fellow citizens, our patients. We have an ethical obligation to speak out when we witness the gradual and unrelenting traumatization of the society in which we practice. This ethical obligation also applies to the clinicians serving patients in the nations with whom we are at war. In all cultures, we know the traumatic effects will endure for generations within these families and even provide a pretext for a future war.

We must not remain silent when we see the human suffering as a result of these wars. That is my challenge to my colleagues in the healing arts of psychiatry, psychology, group and family therapy. That is why we must come to understand the social unconscious in our own nation as I implore in the public address that I gave on line to mental health clinicians in the People’s Republic of China on October 1, 2021.

Read Bill’s Book

The Promise of Group Therapy

“In the future, psychotherapy will be only 25 percent individual. The remainder will be group psychotherapy, not just because it is more cost- effective, but empirical research is demonstrating that many psychological and medical conditions are more responsive to group rather than individual approaches. This book anticipates this trend and is must reading for all psychotherapists and administrators who are designing behavioral health delivery systems, or who may find themselves a part of those systems.” —Nicholas A. Cummings, Ph.D., Sc.D., president, Foundation for Behavioral Health
