David Kertzner founded ProActive English in 1997 to meet a pressing need in the business community as the dot-com era evolved: well-educated, non-native English-speaking professionals with significant roles and great technical ability were not functioning effectively in fast-paced environments due to their language and communication skills.
Similarly, as manufacturing operations transitioned to smart production lines, ProActive English identified a growing need for line workers to communicate more effectively as machinery became increasingly complex and teams became increasingly multicultural and multilingual.
Through ProActive English, David Kertzner has managed training programs at some of the world’s most successful companies, designing training delivery, developing content, hiring trainers and leading training himself at locations around the United States, throughout Asia, in Europe and Latin America. David has also led teacher training workshops in Brazil, Colombia, The Czech Republic, Vietnam (2018 U.S. English Language Specialist) and at many conferences for ESL teachers.
David has passion and skill for generating creative training solutions that are simple, yet sophisticated and engaging for workers in complex global operations. He develops language and communication learning experiences with immediate applications to the work environment which are, often, also personally transformational for training participants.
He earned a Bachelor's degree in Economics from Brandeis University, and received a Master's degree in Teaching English as a Second or Foreign Language from The School for International Training. David now resides in Portland, Oregon with his family where he enjoys playing basketball, completing home repair projects, reading biographies and playing the guitar as if he were a rock 'n roll star.
