I got to know Oliver F. Lehmann as a magnificent Project Management Trainer.
Projektleiter, Zentrale Serviceorganisation bei Zeppelin Baumaschinen GmbH
Ich habe meinen PMP Prep Kurs bei Oliver durchleben dürfen. Hierbei fiel auf, dass seine Vorbereitungen exzellent aufbereitet sind, viele Fälle durchdekliniert werden. Er hat klare Zielsetzungen, fühlt sich seinen Kunden verpflichtet und steht auch im Nachhinein für Fragen zur Verfügung.
Er bietet damit ein All-Inclusive Paket an, das seinen Vergleich sucht.
Oliver played a key role in the development and rollout of training and coaching to support SAP IT’s project management competency development program.
I would certainly engage again with Oliver in the future should the opportunity arise.
PMO Head, Client Partner, Program Manager
I reserve a special note of gratitude for my mentor and trainer, Oliver F. Lehmann, MSc, ACE, PMP. Your 24/7 support and readiness to answer all of our questions was instrumental in my preparation and success.
Marios Bailey
Senior Product Manager @ Munich Re
I participated in a PMP exam preparation course led by Oliver Lehmann. The course was conducted by him in an excellent manner. At no time during the course was it just a dry and boring presentation as he always provided good examples from practice.
His training material was excellent and contained very valuable hints for daily project management situations.

Oliver’s dedication to excellence and his unwavering commitment to success make him an ideal candidate for any endeavor he undertakes.

General Manager at Global Master, Kuala Lumpur, Malaysia
Oliver Lehmann is among the best business trainers. His English is very easy to understand for non-native speakers, which helps students perceive and accept all knowledge smoothly. His course combines theoretical knowledge with a lot of practical cases.
Project Manager at Capita
I want to thank you for this course/session for our chapter members. I received super positive feedback.
Vice President at Intellias, Member of Forbes Technology Council and HBR Advisory Council
Oliver’s enthusiasm and engagement in Project Management related subjects is remarkable and it becomes immediately evident as soon as you’ll start interacting with him.
Agile and Business Coach at Connexxo
I had the pleasure of working with Oliver when we needed a high-quality resource for an engagement in Munich for an international client.
Oliver Lehmann delivered beyond our greatest expectations. Throughout the process, his business style was first class, and the results were superb. The client evaluations were so good that on a 1-5 scale one of the clients gave Oliver a 6!
Enough said, I can’t wait for the next opportunity to do business with Oliver. He comes with my highest recommendation.
Thank you, Oliver; unlike other certifications and training that give you theoretical knowledge that you rarely use in real projects – your information is correct and very practical.
