I work primarily with children, adolescents, and families having difficulty with stress, trauma, (including trauma related to torture experience), depression and anxiety, relationship issues. I also work with new Canadians who struggle with adjustment to the North American culture. I provide both psychological assessment and treatment. I am eclectic with a client-centered approach to therapy. I employ evidence-based strategies, such as Interpersonal Therapy (IPT), Cognitive Behavior Therapy (CBT) as well as Family Systems. Additionally, I offer Psycho-Educational Diagnostic Assessments that help to clarify issues related to Learning Difficulties and other school related concerns.

My goal in psychotherapy is to see my clients develop strategies that help them to effectively deal with life challenges. I bring to partnership relationship with my clients compassion, warmth, empathy, respect and understanding, seasoned by my 20+ years of experience of working with individuals and families from different cultural backgrounds, in Canada, USA and Internationally.

My experience of offering psychological services to families (refugees/new immigrants) who struggle with adaptation issues, adds value to my practice. In addition, as a Christian Psychologist, I also offer service to clients who prefer Christ-centered approach.
