Testimonials

What engineers say about us.

From construction sites to server rooms — here's what our participants think:
"My trainer actually understood my work — the terminology, the context, the pressure. That made all the difference. For the first time, an English course felt like it was built for me."
Thomas K.
Mechanical Engineer
Siemens
"We'd tried general English training before and nobody used what they learned. With DTE, the content was relevant from session one. Our team was using new vocabulary in within weeks."
Sandra M.
Engineering Team Lead
dataport
"No grammar drills, no textbook nonsense. Just practical English for the work I actually do. My trainer had an engineering background, so I never had to explain the technical context."
Markus R.
Process Engineer
ADM
"Our international reports used to go back and forth for revisions. Since the training, that's basically stopped. The improvement in written communication has been remarkable."
Ayşe B.
Project Manager
Airbus
"I was skeptical — I've done language courses before and they never stuck. This was different. Having a trainer who actually understood engineering made it feel immediately relevant."
Fabian W.
Automation Engineer
Mercedes-Benz
"Scheduling was straightforward, sessions fit into a normal working day, and the progress was visible. Exactly what we needed for a busy technical team with no time to waste."
