Learn Our StoryWe review your current situation thoroughly before recommending any changes. You understand exactly what's working and what needs fixing.
We know the tax code, trust law, and estate planning inside out—but we explain it so you can act on it confidently.
Serving families with assets in Canada and the U.S. requires deep knowledge of both jurisdictions. We have it.
Our average client works with us for 6+ years. We grow with your family, not just chase transactions.
We work alongside your accountant, lawyer, and investment advisor—making sure everyone's recommendations align.
Structures we recommend reflect your family's values, not generic best practices. Governance frameworks actually reduce conflict.

We listen to your situation, timeline, and key concerns. No commitment—just an honest conversation about what matters most and where we can help.
We request documents—wills, trusts, tax returns, asset summaries—and conduct a detailed review. This typically takes 4–6 weeks depending on complexity.
We present findings and recommendations in clear language, with specific examples and tax/legal tradeoffs. You see the full picture before deciding anything.
If you proceed, we coordinate with your legal counsel, accountant, and investment advisors. We track and document all changes for complete transparency.
We meet annually to review law changes, family circumstances, and asset growth. Your strategy evolves with you—not left to gather dust.
Families who trusted us with their most important financial decisions.
"We thought our estate plan was solid. Their audit found $240,000 in annual tax inefficiency and a critical gap in how our business transfer was structured. One engagement paid for itself many times over."
"The family office framework they built eliminated the tension in our quarterly meetings. For the first time, my siblings and I understood our roles and how decisions get made. It transformed how we work together."
"Their cross-border expertise was crucial. We have property and investments in both Canada and California, and everyone was giving us conflicting advice. Mastrovalis coordinated everything and gave us a unified strategy."
