OCATT is a group of independent mental health professionals

OCATT therapists specialize in supporting families whose children have experienced trauma; and in support of first responder and military families. Our centre is focused on meeting your needs for individual, couple and family therapy. In addition, OCATT collaborates with multidisciplinary practitioners to provide holistic approaches to healing.

Kim Barthel is a bridge between the science of neurobiology, mental health, and everyday function. She teaches globally about understanding what is behind complex behaviour. Her specialties include attachment, trauma, addiction, sensory processing, movement and learning how we learn and how we can support others.


Becoming a Behavioural Detective:

Understanding and Supporting Complex Behaviour

September 6, 2019 | 9am–4pm
Kanata Recreation Complex, Ottawa, Ontario

There is always a reason for the behaviour!
This one-day workshop with Kim Barthel will provide an understanding of the integrated neurobiology of sensory processing and emotional/relational problems
that result in “challenging behaviour”.

Participants will be invited to forevermore become behavioural detectives, using clinical reasoning, to look deeper than the surface. By seeking to understand why people do the things we do, from a myriad of perspectives, we allow compassion into the equation. This alone changes the brain – but the mindset of clinical curiosity supports treatment strategies at home, at school and in all levels of relationships.

Our Primary Services


Forming a family through adoption is an exciting process that can come with challenges. OCATT therapists use a family-centered approach to celebrate the good and address the challenges experienced by adoptive families.

Post-Traumatic Stress Disorder (PTSD)

When the stress and anxiety of trauma linger long after danger has passed, a person may be struggling with PTSD or Opersational Stress Injuries (OSI). OCATT therapists are experienced in PTSD and OSI treatment with first responders and others.

Fetal Alcohol Spectrum Disorder (FASD)

FASD is complex: it affects executive functioning and mental and physical health. OCATT therapists adapt therapy to meet the needs, and harness the unique strengths, of those struggling because of FASD.

How I Became Aware of the World of FASD

I am a psychotherapist who works with people who have Fetal Alcohol Spectrum Disorder. I have had different opportunities to share my perspectives on FASD through training and facilitating events, but this is my first opportunity to write about my own journey and...
