He articled with the Federal Department of Justice in Saskatoon, Saskatchewan, prosecuting federal offences and received his call to the bar in 1986. He continues to practice law at Semaganis Worme in Saskatoon as well as through his national affiliation with the Indigenous Law Group, who has offices in Ontario and British Columbia.
Mr Worme is a founding member of the Indigenous Bar Association of Canada, a national advocacy group comprising Indigenous lawyers, judges and law students, where he served as president from 1990 to 1992. Mr Worme has also been a vocal member of the Saskatchewan Human Rights Tribunal since 2001.
Mr Worme has served on several Judicial Commissions of Inquiry in various capacities including:

- acting on behalf of the Assembly of First Nations in the 2009 Oppal Commission in Vancouver, British Columbia, which examined the critical issue of missing and murdered Indigenous women and girls; and
- serving as Lead Commission Counsel for the 2010 Truth & Reconciliation Commission, which over its six-year mandate examined the 150-year legacy of the Indian Residential School experience in Canada and its devastating aftermath.
As part of the 100th anniversary of the University of Saskatchewan, Mr Worme was included in the list of the university’s Top 100 Alumni of Influence. In 2010 he was awarded a National Aboriginal Achievement Award for his longstanding commitment to Aboriginal justice in Canada.
Mr Worme is involved in the historic Robinson Treaties litigation taking place in Ontario, which seeks to compel the Crown to live up to the treaty promises and to renew the treaty relationship between the Lake Huron treaty signatories and the federal and provincial governments.
