Gerrit Maßmann – About me.
My motto: from practice, for practice.
Through my various professional stations, I bring extensive knowledge and experience in the fields of sales, communication, and leadership. What I teach, I have experienced myself during my various activities. As a result, I design practice-oriented trainings and coachings and enrich my seminars and my participants.
In addition to my diverse industry and corporate experience, my well-founded and varied training in the fields of training / knowledge transfer, coaching, and communication psychology also helps me.
Thus, you and your employees will experience interesting, practical, and effective trainings and coachings.

Why I love what I do.
I still remember exactly what my boss at the time said to me in the early 2000s. I was working as a temporary employee at a cell phone store, and my boss said to me:
„Pay attention to how you phrase your questions and ask open-ended questions. That changes your conversations, you get more information, and you connect better.“
At first, I was skeptical. But when I began to consciously apply this technique, my conversations with clients actually changed. That experience has stayed with me and sparked something inside me: a passion for communication, learning, and personal growth.
Throughout my various professional stations as a leader in sales, marketing, and training, I have maintained this passion for learning, evolving from a temporary retail assistant in a mobile phone shop to the National Sales Director of an international mobile network operator with responsibility for 250 employees.
Today, I help people discover and develop exactly this potential within themselves—whether as salespeople, leaders, or simply as individuals. Because I’m convinced that there’s far more to every person than they often realize.
With the right tools, practical methods, and a clear focus on individual personality, development, motivation, and sustainable success are created—in sales, in leadership, and in working with people.
How I work.
In my trainings and coachings, I combine practical relevance with sound methodology.
Here are 3 topics that are particularly important to me in this regard
Effective methods that my participants can apply directly
– sustainable transfer into the professional everyday life
– Joy of learning and personal development
What I convey, I have experienced myself and successfully applied for many years in sales, leadership, and communication. This experience is complemented by my professional training and continuous education—including at the Schulz von Thun Institute for Communication.
This is how individual, effective training measures are created that not only motivate, but bring about real change in my participants – practice-oriented, effective, and precisely tailored to your company.
Therefore, my motto is: from practice, for practice.
What I will do for you concretely.

About me personally:
Born in 1975 in Münster and raised in Münster and Ochtrup.
Sales has always been my passion. Even during my school days, I often worked in sales. This enthusiasm continued through my university studies, so that at some point I stopped my teaching degree and started my career in sales.
Many wonderful moments, numerous successes, and interesting and educational professional positions as a leader in sales, marketing, and training in Germany and Austria followed.
Today I work as a sales trainer and coach, sharing my joy of selling and my know-how in this field with my clients and participants.
I am happily married and the father of 3 great children and the happy owner of a lively dog. Besides my family (and the dog), classic and modern classic cars, cooking, cycling, and music are among my hobbies.
My home is the Münsterland region, more precisely Ochtrup. I really like living here and enjoy working here. But not only there. I conduct my trainings and coachings all over Germany and in Europe in German and English, both in online and in-person events.
