Dustan Byrnes

Dustan Byrnes is a third-generation Irish-Canadian, born, raised and remaining in Calgary Alberta Canada. Dustan completed his bachelors degree in Criminal Justice at Mount Royal College (University) in Calgary, including a semester European Study Tour which provided him opportunity to tour throughout western Europe, including back to his ancestral homeland, Ireland. Dustan volunteered for the police service throughout his college education and immediately began his career as a sworn Officer for the Provincial Government, working in forensic technologies and other areas such as consumer protection and maintaining the integrity of critical databases and systems. In 2018, Dustan was promoted to Assistant Director of the Special Investigations Unit, and continues in this employment, overseeing investigations throughout the southern region of the province. Dustan has a beautiful wife, two wonderful children, and his twin sister and parents also reside in Calgary.


Growing up on the footsteps of the Rocky Mountains, Dustan is an outdoor enthusiast and enjoys sports, especially hockey. Dustan has great interest in tracing his Byrne lineage back generations, including back to the 1800’s when his ancestors immigrated from Co. Armagh to Philadelphia USA and into Canada; it was at this time that the family surname of Byrne was changed to Byrnes. One of Dustan’s ancestors is commemorated in a historical park in Edmonton Canada as an incredibly successful entrepreneur and voyager. Dustan’s Grandfather is one of 13 children born in northwestern Ontario Canada into the Byrnes name, resulting in the Byrnes name being spread throughout Canada from this lineage.


Dustan is excited for the opportunity to be a Finte O’Broin Representative to connect with and be a point of contact for Byrne family within Canada and elsewhere.
