Nielsen began his litigation practice by articling with a large, full-service law firm in Calgary in 2021. He joined Parlee McLaws in April 2023. His experience includes labour and employment law, commercial litigation, and insurance litigation. Nielsen was the corporate secretary for a Canadian global affairs thinktank, and has done corporate governance work for a variety of non-profits during his time as a lawyer.

Nielsen has acted for clients before the Alberta Court of Justice, Alberta Court of King’s Bench, and British Columbia Supreme Court. He believes all clients deserve a strong voice and passionate advocate, and strives to ensure that their voice is heard no matter the obstacles that lay in their path. During his time in law school at the University of Calgary, Nielsen volunteered with Student Legal Assistance, providing pro bono legal assistance to clients.

Nielsen served in the Canadian Armed Forces as an Infantry Officer for nearly 9 years, retiring at the rank of Captain. His service included time in the Regular Force with the Princess Patricia’s Canadian Light Infantry, and the Reserve Force with the Calgary Highlanders. Through his time in the military, Nielsen understands the importance of teamwork and cohesive leadership in an organization. He is a passionate Albertan and Canadian, having served in Alberta, Saskatchewan, New Brunswick, Quebec, and British Columbia during his time in the Army.

Nielsen was born and raised in Calgary, and completed both his undergraduate degree in Economics, and law degree at the University of Calgary. Nielsen received the Rocky Mountain Mineral Law academic scholarship during his time at the University of Calgary Faculty of Law.

In his spare time, Nielsen is a sports enthusiast. He plays on two hockey teams during the winter, and is an avid golfer and fly fisherman during the summer. Anytime he gets an opportunity, Nielsen can be found on the Bow, Highwood or Oldman rivers, searching for that elusive trout. He is no less proud to land a whitefish whenever that happens. Nielsen believes it is important to give back to the community, and volunteers in various capacities in Calgary throughout the year.
