About

Two disciplines that usually don't sit in the same room.

US cross border work fails at the seam. The person keeping the books doesn't know what the return will need, the person filing the return has never seen the structure, and nobody is advising before the decision. Lumen was built by two people who spent years on opposite sides of that seam.

Néstor Castillero

Partner, Strategy and Client Experience

Néstor has spent twenty years across law and finance. He cofounded an investment fund with $50 million under management before building a cross border services firm from scratch, which now serves more than 2,000 clients across 60 countries.

He is also the client. A US permanent resident who has lived and worked in Europe, Latin America, and the Middle East, he holds accounts, companies, and assets in more than one country and files the same forms Lumen's clients file. The questions people bring to the firm, which election to make, when to sell, what a move actually triggers, are ones he has had to answer for himself first.

At Lumen he is responsible for strategy, client experience, and the coordination between structure, immigration, and tax. He is based in New York.
