For as long as I can recall, I have had a keen interest in biography. In high school, I read all the biographies in the school library. Although I was registered in mathematics and virtually all my classmates chose university studies in engineering and science, humanities remained a strong interest for me. An undergraduate degree in economics presented a compromise of sorts.


While studying economics, I maintained an interest in better understanding the mind. I read popular literature of the time, including The Myth of Mental Illness by Thomas Szasz, The Divided Self by R. D. Laing, and The Human Person by Magda Arnold and John Gasson. These books and other readings in philosophy, such as Paul Ricoeur’s Freud and Philosophy, Herbert Spiegelberg’s Phenomenology in Psychology and Psychiatry, and Joseph Donceel’s Philosophical Anthropology, had an enormous impact on me.

I was particularly interested in comparative economic systems, as its focus of study included the dynamics of social, economic, and historical relationships in diverse cultures and societal circumstances. In fact, systems theory was quite popular in the early 1970s and was adapted to the mental health field by many theorists in social work and, later, in psychology and psychiatry. Its essential presupposition is that individuals cannot be fully understood without understanding the context in which they live their day-to-day lives. It was probably no surprise that after achieving an undergraduate education in economics, I would decide to pursue studies in psychology.


Having never studied psychology, I applied to the University of Ottawa as they offered a qualifying year of studies in psychology for those wanting to pursue graduate studies in the field. Their psychology program was richly grounded in both the sciences and the humanities and provided an intensive study in philosophical anthropology. The stated orientation of the graduate program in 1975, which was “Christian Personalism in a Pluralistic Context.” It struck me as a bold statement in a society that was becoming rapidly more relativistic. However, the focus on personalism was compelling, insofar as personalists believe that the human person should be the ontological and epistemological starting point of philosophical reflection.

Clients engaging in therapy with me can expect to feel valued. I listen to my clients’ successes and challenges and help clients capitalize on their strengths.  I also treasure my clients’ background and culture.  In the first session, I will listen to your stories and use current research and assessment tools to help with diagnosis.  Collaboratively, we will set treatment goals and a treatment plan.  Whether you are coming to treat mood, stress, or personality, or to learn how to deal with life’s difficult transitions, I will tailor the treatment plan to match your personality and goals.


When it comes to therapy, I have an integrative approach.  Based on the unique personality of my client and his or her goals for therapy, I draw from several empirically supported treatments to suit the client’s needs best.  If you are stymied by faulty thinking, we’ll identify those thoughts and understand what steered you off course. I’ll also help you create a plan of action for better well-being.  Feeling stuck with your goals? I can help you learn how to accept your experiences and circumstances, especially circumstances that cannot be changed. Questioning your life choices and purpose? Together we’ll explore your existential questions and their emotional expression.  In therapy, I help increase the well-being of all my clients and help them achieve what matters most in their lives.

I have a doctoral degree in psychology and have provided individual therapy, couples therapy, group therapy, and psychological assessment in hospital and private practice settings.  I am trained in Cognitive Behavioural Therapy (CBT), Acceptance Commitment Therapy (ACT), Gottman Method, Emotionally Focused Therapy (EFT) Mindfulness-based Meditation, and Humanistic/Existential Therapy.  I have provided services at diverse institutions including the Queensway Carleton Hospital, Jewish General Hospital, Ottawa West Professional Services, the Centre for Interpersonal Relationships, and with Dr. David Crowe in private practice.


I am a member of the College of Psychologists of Ontario, the Ontario Psychological Association, the Ottawa Academy of Psychologists, and the American Psychological Association.
