Two countries, one practice.
Ivanne Tonnessen founded Breton Law APC after years working in U.S. immigration matters. Originally from the south of France, she studied law in Aix-en-Provence and Paris before continuing her legal education in San Diego, where she earned an LL.M. in Comparative Law from California Western School of Law.
Her practice focuses on family, business, and humanitarian immigration matters, with an emphasis on thorough preparation, direct communication, and personalized representation.
Before becoming an attorney, she worked for years as a paralegal in immigration law, experience that shaped her practical and personalized approach to client representation.
Clients work directly with the attorney handling their matter, in English or French, throughout representation.

A few things the firm believes.
-
Direct attorney access.
You speak with the lawyer working on your case. No rotating cast, no handoff to someone you've never met.
-
Clear communication.
Every form and decision is explained in plain language, in the language you prefer. Updates happen on a regular cadence, not only when something is asked for.
-
Cases prepared with rigor.
Filings are reviewed line by line. Evidence is organized. Anticipated questions are answered before USCIS asks them.
-
Clients treated as people.
Immigration cases are personal. The firm's pace, tone, and expectations reflect that: careful, calm, human.
