Operations Manager (Manufacturing) (Carlos)

“I supervise many employees and I am in charge of several manufacturing sites in Mexico. Before working with Jonathon, I understood English but struggled to speak confidently in meetings. His classes are practical and focused on real situations. Now I participate actively in calls with our U.S. team and feel much more confident.”

HR Business Partner (Laura)

“Jonathon doesn’t use generic books. He creates his own lessons and a lot of what he teaches is from real-world business experience. Every class is customized to my work in HR—interviews, difficult conversations, and presentations. I stopped translating in my head and started thinking in English. I know he puts in a lot of time creating his lessons.”

Corporate Executive (Miguel)

“I’ve taken many English courses, and I thought my English was pretty good, but Adelante English is completely different. Jonathon showed me things I never learned anywhere else. The classes feel like real conversations, not lessons. My speaking and listening improved faster than I expected.”

Logistics & Supply Chain Professional (Andrea)

“Jonathon doesn't spend a lot of time on grammar and vocabulary. He says that is learned organically working on lessons that are more practical and I agree. The role-plays and listening exercises are exactly like what I hear in real meetings. Jonathon understands business and explains everything clearly. I use what I learn immediately at work.”

Engineer (Daniel)

“When Jonathon moved to Mexico in 2021, he had to learn Spanish, so he understands how Spanish speakers think and where we struggle. He explains English in a way that finally makes sense.
