Obituary For Mark Bradley Justin Petroski

Mark Petroski, resident of Horse Lake First Nation, passed away on Thursday, January 5, 2023, at Horse Lake First Nation, at the age of 37 years.

Mark was born on August 30, 1985, in Grande Prairie, AB, raised in Horse Lake. He attended elementary school in Hythe, AB, and high school in Beaverlodge, AB. Mark was the Band Councillor for 8 years, and was a welder in the oil and gas industry.

Mark loved all sports - mostly hockey, slow-pitch, golf, watched UFC, and boxing. He also loved camping, hunting, quadding, drawing, and spending time with family and friends.

He had a great sense of humour. The most contagious smile that could light up any room he walked in.
