Gessimbergue ("Gessie") Monteiro

ESq., LL.M.

Gessimbergue Monteiro is more than just a dual-licensed attorney in Florida and Brazil, he is a trusted guide for Latin America’s most prominent families and entrepreneurs navigating the complexities of wealth, legacy, and life transitions in the United States.

With deep expertise in U.S. and international tax law, estate planning, trust structuring, and cross-border wealth preservation, Mr. Monteiro brings clarity and confidence to (ultra) high-net-worth families as they prepare for generational change and global expansion. His clients who are traditional Latin American dynasties, visionary entrepreneurs, and seasoned executives, rely on his strategic insight not only to protect what they’ve built, but to ensure it thrives across borders and generations.

Whether he's designing sophisticated pre-immigration tax strategies for Brazilian executives relocating to the U.S., advising family offices on governance and succession, or restructuring international holdings to support real estate investments, Mr. Monteiro operates at the intersection of legal precision and cultural nuance. His practice is rooted in discretion, foresight, and a deep respect for the traditions and ambitions of the families he serves.

A frequent board and committee advisor to family-led enterprises, Mr. Monteiro is known not only for his technical acumen but for his calm presence in moments that matter. For families looking to steward their legacies with intention and impact, he is both architect and ally.

Mr. Monteiro’s thought leadership in the field is reflected in his published work, including the article “Brazilian Investment Funds and US Pre-Immigration Tax Planning” (co-authored with Felipe Medaglia), which appeared in the Tax Management International Journal by Bloomberg Tax in August 2023. He remains actively engaged in the professional community through his affiliations with the Tax Section of the Florida State Bar, the Society of Trust & Estate Practitioners (STEP) Miami Branch, the Greater Miami Tax Institute (GMTI), and IBRAPP – Instituto Brasileiro de Planejamento Patrimonial. His reputation in the field is also recognized by Chambers & Partners, where he is listed in the Florida Spotlight Guide 2024/2025 for Trusts & Estates. Gessimbergue is admitted to practice law in both Florida and Brazil, allowing him to serve as a truly cross-border advisor to his clients.
