About us

Long before Effective Enterprise was established we have been providing English teaching for adults and consulting in operations management and lean.

We have been working for quite some years independently until we joined forces at Effective Enterprise. Clients we serve are professionals who need to increaste their knowledge in specific knowledge area or to improve their English language skills. Sometimes our clients require custom-tailored training programs which we develop in close cooperation with the client. Some trainings are individual, though we mostly work with groups.  

We never outsource trainings to other companies as it will inevitably introduce quality risks.
