Zachariah Zagol
Operations Director · LL.M. USC · First American to pass the OAB
Zachariah Zagol came to Brazil at age 18 from the United States with a decision that would change his life forever: he wanted to build his future here. Not as a tourist, not as a passing expatriate — but as someone who chose Brazil as home.
He completed his law degree in Brazil and became the first American citizen to pass the OAB Bar Exam. He then earned his Master's degree (LL.M.) in International and Real Estate Law from the University of Southern California (USC), building an academic background that flows naturally between two legal systems.
But what truly sets Zac apart isn't his diploma — it's his lived experience. He is an entrepreneur, real estate investor, and operator of multiple businesses in Brazil. He's built a Brazilian family, raised children between two cultures, and understands that Brazilians are incredibly welcoming people who know how to live life in a way that few places in the world can replicate.

Our Philosophy
Why We're Different
We chose to be a boutique firm — small by design, not by lack of ambition. Explore our practice areas.
Relationships First
We want to know you, your family, your goals. Because when we understand you, we can chart the best path.
Ultra Specialists
We don't try to do everything. We do a few things with depth and dedication that general practice firms can't match.
Value, Not Volume
Our fees reflect our quality. When it comes to assets and family, the question isn't "How much does it cost?" — it's "What's peace of mind worth?"
"Not just anyone can handle these cases. We're dealing with families, with assets built over entire lifetimes, with inheritances that need protecting. All of this requires more than someone who knows the law — it requires someone who knows the culture, who can explain and guide at every step."
