Estate planning, tax-efficient structures, and family office guidance designed for multi-generational wealth across Canada and California.
Serving families and business owners across North America since 2019
We don't sell products. We audit your current structures, identify tax inefficiencies, and build a plan aligned with your values and goals. Your wealth serves your family—not the other way around.
Our team has guided multi-generational families through business transitions, estate distributions, and cross-border tax planning. We know the gaps. We know the solutions.
Three integrated disciplines. One coordinated strategy. Built exclusively for high-net-worth families.
Comprehensive review of wills, trusts, and beneficiary designations—with actionable recommendations to reduce tax leakage and clarify succession intent.
Strategic entity design and restructuring to minimize lifetime and estate tax exposure while maintaining operational simplicity and compliance.
Governance frameworks, investment coordination, and family meeting facilitation—helping multi-generational portfolios operate with clarity and consensus.
The principles that define how we work and why our clients stay for decades.
We begin every engagement with a full audit of your existing structures—no assumptions, no shortcuts. You deserve to know exactly where you stand before we recommend anything.
Canadian and U.S. tax law in one integrated advisory. We handle the complexity of cross-border holdings, dual-status families, and multi-jurisdiction estates with precision.
Flat-fee and retainer engagements only. No commissions, no product conflicts. Your advisor's incentive is your success—and nothing else.
With an average client relationship of 5–7 years, we build lasting partnerships that evolve with your family's circumstances, not transactional engagements.
What our clients say about the difference a rigorous, independent advisor makes.
After working with two previous advisors, Mastrovalis was the first to actually audit our trust structure and explain what we were overpaying in taxes. They saved us $180,000 over three years and gave us a clear roadmap for our kids' inheritance.
"We needed someone who could navigate both Canadian and U.S. tax law for our cross-border holdings. Their team didn't just answer our questions—they anticipated the ones we hadn't asked yet."
"The family office advisory service gave us a governance structure that actually works. For the first time, our quarterly family meetings are productive instead of fractious. That alone is worth the engagement."
Four disciplined steps from discovery to ongoing stewardship of your family's financial legacy.
We review your current documents, structures, and tax filings to identify inefficiencies, gaps, and opportunities across your full wealth picture.
We model scenarios, compare outcomes, and build a clear, written plan aligned with your goals and values—presented in plain language, not jargon.
We guide you through execution, coordinate with your accountant and legal counsel, and document every decision for the record.
We monitor changes in law, your family circumstances, and asset growth—updating your strategy proactively rather than reactively.
