Psychological Assessment

Are you or your child in need of a psychological or an educational assessment?




I am a Registered Clinical Psychologist in Barrie, Ontario, who has been practicing since 1991. I am pleased to offer psychological and psychoeducational aassessments, and individual and group therapy to children over the age of 6, teenagers, and adults. I work with a variety of psychological difficulties that include, but are not limited to, anxiety, depression, grief, learning disabilities, obsessive-compulsive disorders, stress, and trauma. I also offer speaking engagements, and provide consultations to other professionals. I combine the latest relevant research with the individual’s unique strengths to provide a tailored treatment approach. Services are often covered in part by workplace benefits, and private health insurance plans.




Tailor-made seminars and workshops on a variety of mental health topics.

Coping with Panic Disorder

You may be relaxing, and suddenly, out of the blue, feel as if you're having a heart attack, you can't breathe, your legs start to tremble, your chest hurts.  You may be among the many who may be experiencing a panic attack.

Raising distractible kids to like themselves
Staying focused on challenging tasks can be very frustrating for some children.  Not only may their academics suffer, but also their self-worth and self-esteem.
