Carlos's English was technically B2 by HR's measurement. In real meetings — defending an engineering budget against a finance lead who was pushing back — Carlos froze. He had the vocabulary; he didn't have the confidence to use it under pressure. His promotion track depended on solving this.
Matt made me realize my English wasn't broken — my CONFIDENCE was. After 4 months I led a $2M budget defense in English and didn't choke once.
Matt Anderson's professional-English cohort + 1-on-1 mock-meeting practice broke Carlos's freeze pattern. They recorded every session so Carlos could hear himself; the recordings showed how much he hesitated. Within four months the hesitation was gone. The promotion came six months later. Carlos now mentors junior engineers at his company who have the same problem.
