About Shannon

Copper Coast, Co. Waterford, Ireland

Professional Profile

Accent Canadian, Passport Irish, and today I call Dungarvan, Co. Waterford, Ireland home; the most southern part of the Republic of Ireland. I live here with my best friend and partner, Leo Cullen, and our Bernedoodle puppy, Maggie (as in Magpie). You can find us most mornings swimming at Clonea Beach, The Cove, Ardmore Beach, or Dungarvan Beach. 


My 'adventures' (aka complex trauma) have taken me from Canada to Ireland, the UK, all over the the Middle East, North Africa, Turkey and at this point most of Europe. 

The areas of Mental Health and Human Behaviour have been of great interest to me for as long as I can remember, circa aged 5. I attribute this to a very challenging early family life and an ever-present curiosity as to why people do what they do, which over time informed the more personal question - why do I do what I do.

Since the age of sixteen, when I secured my High School Diploma, Irish passport, and left Canada for Europe on my own, my life’s passion has been the pursuit of personal and professional development.

For well over a decade, this largely consisted of personal healing through self- and group-work and the guidance of trusted teachers and mentors.

After more than 20 years running my own business working in the area of human behaviour and business growth, my focus shifted to trauma-informed growth, performance and leadership circa 2018. 

I am an avid reader and researcher; and the area of Complex Post Traumatic Stress Disorder (C-PTSD) is of particular interest.


Authors, and specialists in this area, such as Pete Walker (C-PTSD), Bessel van der Kolk (PTSD), Pete Burgess (Polyvagal Theory), Bruce Lipton (Biology of Belief) and Gabor Mate (Addiction) have been particularly influential in shaping my views and aiding my own personal development.


Before 2018, I would have been a loyal student of Carl Jung - I have a 2-year Jungian Psychology Diploma obtained in 2019 from Ireland’s Jung Society led by Dr. Jasbinder Garnermann, - and a decade long student of Dr. John Demartini. 

Fast-forward to 2024, and I am about to complete my MSc in Mind-Body Psychology at University of East London, in preparation for my PhD in Complex Trauma / C-PTSD at work. 


After 20 years working in the Financial Services industry with both Tech Start ups and Enterprise on 3 continents, my experience demonstrates time and time again, that C-PTSD at work, is accountable for a large portion of the challenges businesses face in the area of recruitment, culture, productivity, sales and innovation.

I blog about C-PTSD, Business and Trauma-Informed Growth at work, here on this site. I talk about it on my podcast, and I have written, illustrated and published 18 books scientifically designed for professionals to practice mindfulness and recover from C-PTSD.
