Dr. Lorraine Champaigne

Dr. Champaigne, is a Clinical Psychologist who has extensive clinical training and experience providing assessment and treatment for brain injury, rehabilitation, mindfulness and sleep therapies for adults, children and youth, since 1980. She has worked in a range of settings including hospital, out-patient mental health clinics, elementary, secondary and post-secondary schools as well as in private practice. Before becoming a psychologist she first worked for 2 years as a Child Care Worker with the Regional Children’s Psychiatric Center (RCPC) in-patient program of the Sudbury Algoma Hospital (SAH) with emotionally, socially and behaviourally disturbed children and adolescents in a milieu setting. Working under a neuropsychologist, she then trained as a Psychometrist assessing both children and adults before becoming the Psychometrist for the RCPC in-patient unit for another 4 years. Her clinical training then expanded to include the treatment of children and adolescents and their families using play therapy, individual and family therapy through the out-patient Child and Family Center English/Centre de l’enfant et de la famille for 9 years. She entered the doctorate program in Clinical Psychology at the University of Ottawa and worked part-time as an associate in a group private practice in Sudbury while completing the requirements of the doctorate. She earned her PhD in 2000 and completed requirements for registration as a Clinical Counselling Registered Psychologist with the Ontario College of Psychologists in 2002 (#3748). As a bilingual native of Sudbury, she had previously obtained a BA (Honors) degree in psychology from Laurentian University and a MA in Education and Supervision from Central Michigan University.

Dr. Champaigne and Dr. Klassen joined their private practices in 2002 offering full-time psychological and consultative services with a team in an active and diverse practice. Dr. Champaigne offers bilingual individual, couple and family based treatment services for a range of trauma, adjustment issues, health problems, learning, behavioural, emotional and relationship difficulties involving children, adolescents, adults, couples and families. The provision of learning disability assessments has been a keen interest of hers for over 30 years. She has also been working in the rehabilitation field providing clinical services to individuals of all ages with acquired brain injuries and adjustment difficulties following injury.

With the mounting evidence of the mind’s capacity to affect the body, the mind-body connection that defines many of the problems that people seek help for became a strong interest. Dr. Champaigne developed an understanding of learning and brain-based correlates and obtained extensive training and experience in biofeedback, neurofeedback and neurocognitive remediation as adjunct therapies. She is passionate about offering treatment that affords an alternative to the use of medications for problems associated with sleep, attention, anxiety, depression and trauma in both children and adults. She obtained levels 1 and 2 EMDR (Eye Movement Desensitization and Reprocessing) certification in the early 1990s. She has sought extensive training in her fields of interest and practice. She is currently training in Mindfulness Based Stress Reduction (MBSR) through the University of Massachusetts medical school. While Dr. Champaigne is trained in Interpersonal Therapy, Cognitive Behavioural Therapy, Emotion Focussed Therapy, Acceptance and Commitment Therapy, Family Systems Therapy, Behavioural Therapy, Biofeedback/Neurofeedback, and Hypnosis, she takes an eclectic approach as she views each person as unique whose needs do not fit into one particular model of treatment. She is also passionate about developing and maintaining a strong therapeutic alliance with her clients as they work together in resolving problems.

Over the years, she developed a very keen interest in treating all types of trauma and PTSD, which then led to treating military personnel in 2010. She has been recognized for her excellent work with the veteran community. She also has a passion for helping people recover from various losses they have suffered which led her to become certified as a Grief Recovery Specialist.

When Dr. Champaigne is not working, you can find her learning new things to share through cooking and entertaining with family and friends, travelling, reading, enjoying nature through kayaking, swimming, skiing, snowshoeing, and hiking, and also supporting the arts. She is married and the mother of three adult girls.
