Dr Boysen graduated from the Western College of Veterinary Medicine (WCVM), Saskatoon, Saskatchewan in 1996, worked in private practice for a year and then completed an internship at the Atlantic Veterinary College in Prince Edward Island.

Dr. Søren Boysen joined UCVM in January 2009. He is a Professor in small animal emergency and critical care in the Department of Veterinary Clinical and Diagnostic Sciences.

He is actively involved in both the American and European veterinary emergency and critical care societies, as well as the Veterinary trauma initiative, serving on several committees for these organizations.

He is an internationally recognized lecturer, speaking at numerous international conferences around the world. Although he is happy to speak on any small animal emergency and critical care topic his true passion lies within emergency point of care ultrasound, perfusions, hemorrhage and shock.
