Direct Selling

In an American company like Amway, English is the corporate language and an integral part of our daily business. The concept of PLS is tailored to the position and function of each and every employee. The native-speaker trainers create and teach their programme based not only on the individual and personal needs of their learners, but also adapted to the language level of each participant. PLS is extremely flexible at all times and this flexibility is combined with the highest competence. The institute has been our strong partner in language training for more than 10 years.

The content of the PLS courses is selected based on our daily work in order to be able to cater for the needs of the groups and each individual participant. Super trainers, flexible, uncomplicated, excellent organisation – hardly any organizational tasks left for the companies themselves. Regular tests and therefore excellent feedback and reporting regarding the progress of the participants. All in all, simply super!

Professional Language Services holds weekly courses at FlowCAD, especially for employees who have to communicate regularly with our English-speaking customers and suppliers. Thanks to the very individual training courses, tailored to the specific needs of FlowCAD, the efficiency of our processes and email correspondence has greatly improved. PLS trains not only language skills, but also intercultural understanding with Anglo-Saxon countries.

In my opinion, the direct exchange of information and ideas during our translation projects is very positive. The close connection when it comes to complex terminology and texts vastly reduces the time needed for proofreading and correction. That makes Professional Language Services stand out from its competitors.
