Here are some further details about my areas of specialty.

Psychodrama and Drama Therapy

My primary trainer in psychodrama was Zerka Moreno , co-creator (with her husband, J.L. Moreno) of classical psychodrama, and recognized around the globe as a leader in the field. I also received accreditation as a Trainer in the Therapeutic Spiral Model for the safe utilization of psychodrama with trauma survivors.

In 1989 , I created ACTINGOUT, a program for youth in New Hampshire that combined expressive arts group therapy with training and performance opportunities in issue-oriented theatre. I directed this program through June of 2003. I am recognized by my peers as a leader in the field of psychodrama with adolescents and have conducted workshops around the world on utilizing action methods with adolescent groups. My book, REBELS WITH A CAUSE: Working with Adolescents Using Action Techniques (August, 2005 – Jessica Kingsley Press, London ) contains a Foreword by Zerka Moreno and details the philosophy, theory and practice of this work. (For details please go to Publications .)


I am the proud creator and developer of Drago-Drama, an archetypal form of sociodrama/psychodrama for exploring personal dragons and the treasures that they guard. With collaborators from ACTINGOUT, I’ve developed an original musical: WHAT THE DRAGON STOLE, based on the Drago-Drama theme. Drago-Drama workshops for educators as well as for personal growth with adolescent and adult participants have also been conducted internationally, in the USA , South Africa , and Australia . (Please see Trainings Offered)

Theatre Education

While working with ACTINGOUT, I developed a unique brand of issue-oriented, audience-interactive, improvisational theatre focusing on contemporary issues such as substance abuse, violence prevention, and HIV. In 14 years of my direction, ACTINGOUT offered over 1,000 performances, presentations and workshops. On some occasions we were brought in to address a particular issue besetting a particular school community (sexual harassment, bigotry), or to serve as Keynote presenters at youth and adult conferences throughout New England . During this time I also was certified as a trainer in a number of science-based, prevention curricula focusing on Violence Prevention, Substance Abuse Prevention, and HIV Prevention/Education.

Additionally I have over 40 years experience as a theatre director, actor, and choreographer. I have worked with youth and adults in comedy, drama, and musical theatre productions and have also been a teacher of clowning and circus arts.

Community Organization

The Monadnock Region of NH, where I worked for over 30 years, is known throughout the state for both the amount of and effectiveness of collaboration between and among youth service providers. I am proud to have been part of the organizing forces that helped create and develop a cooperative spirit among providers in this region.

Internationalization and Multiculturalism

In 2005 I joined an on-going project at Monash University in Victoria , Australia , bringing action methods to their exploration of issues of internationalization and multiculturalism in higher education. I was excited to conduct a workshop at Monash with representative from several Victoria campuses, their South Africa Campus, a visiting professor from Sweden , and Monash students from both Australia and Russia . I then worked with with Monash staff on an International Conference focusing on these issues, to be held in Malaysia in February, 2006.

Organizational Development

I have developed a workshop for organizations that employs Role Analysis (as developed by psychodramatists in Australia and New Zealand) to explore the organizational system from a perspective of which organizational and interpersonal roles are present or absent; helpful or hindering; and underdeveloped or overdeveloped. The workshop also focused on issues of role development, role training, and role fatigue.
