  • José Millán is a key figure in the regulatory field, and his interpersonal skills are one of Andersen's major differentiators compared to other firms. He is particularly known for his honesty and transparency, always putting himself in the client's shoes, which makes him deeply knowledgeable about the client's business and a crucial asset in strategic regulatory advice.
