Mark Mercier
Sherry (Assistant): sherry@mercierfamilylaw.ca
Mark received his Bachelor of Law degree from the University of Manitoba in 1996 and was called to the Bar in 1997. He has practiced family law exclusively since that time, covering all areas of domestic law including custody and access, support, property, child protection, and pre-nuptial and post-nuptial agreements.
Prior to attending law school, he obtained a Bachelor of Arts degree with double honours in Economics and Political Science in 1991, before taking some time off to work as a speech writer and executive assistant to the then Provincial Minister of Justice.
Since 2005, upon opening his own firm, his focus has been to provide quality service to all clients as they go through difficult times, focusing on reaching an agreement where possible, and proceeding to court if necessary.
Away from the office, he spends his time coaching competitive soccer, fishing (both recreationally and in competitive catfish and walleye tournaments), and volunteering in a non-profit board and foundation that provides services to mentally and physically challenged adults who live and work in the community.
Alicia Sawka
Hanna (Assistant): hanna@mercierfamilylaw.ca
Alicia received her undergraduate degree in 2003 from the University of Winnipeg with a double major in Sociology and Conflict Resolution studies. For Alicia, these interests naturally led her to law school. Alicia graduated from the University of Manitoba, Faculty of Law in 2006, and was called to the Bar in 2007.
Alicia has practiced family law primarily since her call to the bar, and exclusively since 2010. She believes in giving her clients all the information they need to make decisions that impact their family and assisting them in making informed decisions. Alicia has training in mediation and collaborative family law and uses this to assist her clients in proceeding in a collaborative or cooperative fashion. In circumstances where negotiation fails, Alicia has ample experience litigating through the family court system.
Away from the office, Alicia spends most of her free time chasing after her two sons and keeping up with their activities. She also volunteers with the Legal Help Centre, the parent advisory council at her son’s school, and is the Chair of her children’s daycare board.
