Thank you for taking the time to explore Auditory Pathways.
Here is some information about my approach and clinical background for assessing and treating auditory processing disorders.


I am passionate about the work that I do. I am also committed to giving my best to my clients.  It takes more than a simple prescriptive method for the diagnosis and treatment of an Auditory Processing Disorder.  Helping children and their parents understand Auditory Processing Disorder is a large part of what I do as a professional It is possible to live and thrive with an Auditory Processing Disorder!


Auditory Processing Disorders can be identified and treated with appropriate testing and therapy approaches.
Due to the Covid-19 Global Pandemic, all services are now offered remotely to residents of Ontario. These evidence-based approaches have worked well for children and teens as they access testing and therapy services from the comfort of their own homes. 


Based on my 33 years of clinical experience, I discovered there was a need for a dedicated practice to serve children and teens with Auditory Processing Disorders.  Due to the complex nature of these disorders, it became clear to me that I had to further expand my education to meet the unique needs of the children and families I serve.
To this end, I have dedicated my clinical time to the study of Auditory Processing Disorders.

My professional education includes a Bachelor of Science in Speech-Language Pathology from   Colorado State Universityand a Master of Arts in Audiology from the University of Northern Colorado  with advanced studies in Educational Audiology. Following internships with the Boulder Vallery District School Board in Boulder, Colorado and the Colorado School for the Deaf and Blind, in Colorado Springs, I decided that working with children and teens was definitely going to be part of my future.

After 15 years of clinical practice, I returned to student life and completed a Doctor of Audiology through   Salus University, Osborn College of Audiology with Advanced Studies in Tinnitus and Hyperacusis.

Over the past 10 years my continuing education has brought me a greater depth and breadth of knowledge, understanding, and compassion which has taken my practice as an audiologist to a higher level.

Additional Coursework Includes:

  • Tinnitus Retraining Therapy with Dr. Pawel Jastreboff
  • Certificate of Advanced Studies in Tinnitus and Hyperacusis, Salus University

Individuals with Auditory Processing Disorders, ADHD, or who are on the spectrum, will benefit from the evidence-based assessments and therapies offered. These are grounded in neuroscience and can bring about profound neurological changes. These neurological changes help overcome weak or inefficient processing resulting in improved learning and communication abilities. This helps not only in the classroom or work setting but in all areas of life.
