She has practiced in a wide variety of roles over the course of her career (consultant, psychologist, registered psychologist – provisional, educator, trainer, group therapist, and some of her work has included diagnostic assessment impressions, support, intervention, problem-solving sessions, letter, reports and/or consultations via Skype/Zoom or in-person. On her ‘psychologist’ role, Tania was an approved Medicare Registered Provider of Psychology Services, an approved APS Identified Autism Practitioner, a Helping Child With Autism approved provider, a Better Start for Children with a Disability Provider and a trained Secret Agent Society (SAS) Trained Group Facilitator. Currently, Tania divides her time between private practice, her contract work, writing her book series and research. Tania’s work has been translated and/or cited in numerous publications including Sarah Hendrickxs’ recent release entitled “Women and Girls with an Autism Spectrum Disorder” (June, 2015).

Over 30 years ago, Tania volunteered at an out-patient day centre and worked with adults with a variety of conditions, including schizophrenia, bi-polar disorder, and also what would now be known as adult Autism and Asperger Syndrome. Tania then attended University, receiving her Bachelor of Arts, majoring in Psychology. During that time of working on her initial degree, she also was a psychology research assistant (Autism and related developmental conditions and childhood disorders) and spent three summers working at a special needs camp, in the capacity of camp counselor and then as a psychology assistant. She worked with many individuals on the Autism Spectrum.

Tania then completed a Masters of Science degree. During her Masters degree training she completed a supervised internship at a Children’s Hospital in the ADHD/Disruptive Behavior Disorder Clinic, where received training an experience in assessing, diagnosing, supporting and providing intervention to children and their families affected by ADHD, Autism and related conditions. During that time she was a recipient of three scholarships and three teaching assistant positions. Her Masters degree involved the completion of 12 courses in addition to an original supervised Masters’ level thesis.

After the completion of her Masters of Science degree (Applied Psychology, Developmental/Educational psychology), she then completed a supervised 18-month post Masters externship (supervised by a Clinical Psychologist) at a private special needs school for children from Grades 1-12, who were “at-risk”, had dropped out of school, been suspended, were in foster care, in contact with the justice system, abused, and/or had a variety of disorders and/or conditions. Some of her duties included: providing diagnostic assessments, psycho-educational assessments, psychological assessments, intervention, support and therapy, family therapy, report writing, stakeholder meetings and visits to hospitals to see students. She supported students of all ages, both genders and their families, all with a wide variety of conditions, learning difficulties and concerns. She worked with many students with Autism or Asperger Syndrome. She worked with females on the Autism Spectrum when very little was known about Autism in females. She also completed an 18-month post-Masters externship in private practice, supervised by a Clinical Psychologist.

Tania attended Dr. Ross Greene’s “The Explosive Child” one-day seminar, briefly meeting him and discussed children with Autism and related conditions. Tania stands firm in her belief that the vast majority of children want to please their parents…IF they can. If they cannot, it is our job to find out what their lagging skills are and assist them. She is a strengths-based practitioner, assisting others to focus on their strengths whilst being supported with their challenges.

Since then, Tania has worked in private practice, providing a wide variety of assessments and services to people of all ages. She has worked with many thousands of individuals of all ages with varying expressions and sub-types of autism/neurodivergence and conditions/disorders, including personality disorders. A large majority of individuals she has worked with are twice-exceptional, (Gifted and Talented) and Neurodivergent.
