Peggy Claude-Pierre's counselling background includes work in family mediation and prison inmate programs. As part of her undergraduate work in Psychology she undertook a major study in recidivism among young offenders involving over 20 countries. From this experience, she intended to make a career of prison reform and the counselling of "troubled" youth and street children. Her findings that positive reinforcement was more effective than punishment helped her to refine the approach of "unconditional support" employed at Montreux today.

When Peggy's two daughters became (successively) ill with anorexia, formal studies were put on hold as she became the girls only hope for survival. The nightmare of nearly losing her own children evolved into a mission to enlighten society as to the true nature of this devastating disorder. Following the recovery of her daughters, referrals from fellow professionals induced her to open an out-patient practice specializing in eating disorders in 1988. Concurrently, she pursued graduate studies with the Adler Institute of Chicago. The demands of desperate parents, however, forced her to forego further education in order to concentrate on saving the lives of critically ill children. The Montreux Counselling Centre began its residential in-patient program in 1993. Following their demonstration of success with "hopeless" cases, Peggy and her team have been greatly encouraged by the emerging enthusiasm of the professional community to embrace a more humanistic treatment model. They have worked closely with treatment teams in acute care hospitals where patients must often be stabilized before they can be brought to the Montreux clinic.

The Montreux Counselling Centre's Eating Disorder Program has only one aim for all patients: total recovery without recidivism. While there are inevitable drop-outs before program completion, over 90% of those admitted do achieve this goal. The Program is licensed under the Community Care Act in British Columbia, Canada. Admission is strictly through medical referral and all patients are closely medically monitored through all stages of treatment. Patients' treatment costs have been covered by a number of major health insurers including: Prudential, MetLife, CHAMPUS, WPS, HealthNet, etc. Montreux has treated patients from over 10 countries on 4 continents.

Peggy Claude-Pierre's gentle yet positive approach to the treatment of anorexia and bulimia has been introduced to millions throughout the world thanks to a number of television productions sensitive to the issue. In North America, ABC-TV's Peabody Award winning 20/20 episode of December 2, 1994, gave many people their first glimpse of the deeper torture experienced by the victims of eating disorders, as well as the hope of complete recovery. There followed two further 20/20 airings, two Oprah episodes (seen world wide), as well as productions from Spiegel TV (Germany), Dutch Nation Television (Netherlands), Current Affair (Australia), Pointe de Mire (Canada), and several in the U.K.

Peggy Claude-Pierre has consulted with numerous professional colleagues and government representatives in North and South America, Western and Eastern Europe, as well as Japan, Australia, New Zealand, and South Africa. She has been nominated for the Kiwanis World Service Medal (she was relieved to have lost to Mother Theresa), and the Institute of Noetic Sciences Altruism Award. Her philosophical development has been influenced by Alfred Adler, Abraham Maslow, and Elizabeth Kubler-Ross, among many others.

Currently, Montreux staff are in the process of creating a teaching clinic in order to facilitate the thousands of requests they have received for a professional training program. Further plans also include a formal long-term outcome study.
