Tristan provides strategic, practical, and results-oriented advice to individuals navigating complex family law disputes. He recognizes that these disputes extend well beyond the courtroom, often affecting relationships, finances, businesses, and families. Tristan believes effective advocacy begins with careful preparation and clear communication. He takes the time to prepare clients for every stage of the litigation process – including negotiations, mediations, hearings, trials, and appeals – ensuring they understand the legal issues, the strategy behind their case, and what to expect throughout the process.

Tristan’s practice is devoted exclusively to family law. He represents clients in parenting disputes, child and spousal support matters, property disputes, trust and equitable claims, and marriage, cohabitation, and separation agreements. He has a particular interest in and experience with financially complex family law matters involving high-net-worth individuals, privately held businesses, professional practices, trusts, pensions, and sophisticated valuation issues.

An experienced litigator, Tristan has represented clients at every level of court in Ontario, including the Ontario Court of Justice, the Superior Court of Justice, the Divisional Court, and the Court of Appeal for Ontario. He combines meticulous preparation with practical advocacy, recognizing that some disputes require decisive courtroom representation while others are best resolved through skilled negotiation and alternative dispute resolution.

Tristan has taught legal ethics to paralegal students at St. Clair College, continues to mentor law students through the Windsor Law Practice Simulation (WLPS), and has been invited to speak at continuing legal education programs and professional conferences on family law topics.

Committed to his community, Tristan serves as a board member of New Beginnings, a non-profit organization supporting children, youth, and families, and remains active in several other community and professional organizations.

Having experienced the challenges of divorce firsthand, Tristan understands the uncertainty that often accompanies family law disputes and is committed to helping clients navigate difficult transitions with confidence.
