Head of Heat Exchanger Mechanical
Dept. Chez GE Power

I can only recommend Steffen as a leader and a
coach. Despite his busy agenda, he has always
found time to support and coach me, providing
very valuable and pragmatic advices, based on
his rich professional career and his personal
life. He is definitely an inspiring leader, acting
efficiently and fairly. I still keep in mind some
of his advices and apply them daily!

Patrick Maffeis

Global Operations VP at Wavin, a
Business of Orbia

I got to know Steffen as he was leading a
complex transfer of technology between
Switzerland and Germany To the US for Alstom
Power. A very tight project under both time and
cost pressure. From day one I was positively
impressed by his leadership, sense of
organization but also his ability to dig in the
details. Earmarked him as a talent for the
future.

Naturally some months after I selected him to
lead our global industrial team on the
development of our top end product. A very
challenging one as we were targeting a
performance never met yet on the market but
also tasked us with a very competitive cost in
order to offer the best value for money on the
market of giant gas turbines. I have been
working very closely with him during the 2
years of development and he has proven again
a great leadership, robust team playing
attitude, fostering on what was best for the
company. He was very successful in on-
boarding other functions to design a product
that would meet our lean concept for
assembly, to push our technicians and
suppliers to deliver capable components and
was a strong contributor to deliver our best gas
turbine ever. All this in a very positive mindset
and just asking for top management support
when he had exhausted all possible solutions.


I still remember the comments of our assembly
team after building the first prototype: << last
time we had to review more than 100 parts or
dimensions, this time 5 minor adjustments
were sufficient to make it >... think about this
the complexity of a jet engine in a baby of 500t
assembled in time with 5 minor adjustments
after 2 years of development! Great
performance for which Steffen deserves my
deep recognition. His skills and talent are those
of a robust leader.

 Udo Metz

Head of COE Parts Solutions, Germany

Steffen is probably the manager who has impressed and influenced me the most, and there have been quite a few. He is on of the best connectors I know. With his "bring the
teams together" menatality and his open manner, he has impressed me very much. He is the master of crossfuntional. Steffen is a family man, not only in his private list but also with his team. Not only do you feel
that way, but you are also treated that way. He also takes a lot from his team adn gets suggestions from them as well. He has a vidion that he exemplifies while giving his
team a free hand to achieve it.

Leah Kendrick

Global Parts Operational Excellence Leader
at GE Power

Working 'with’ and working 'for Stephen is the same thing. Steffen treats everyone the same, he is very open, honest and fair, both as a leader and as a colleague.

My ideas and opinions are always listened to by Steffen, and when I make a mistake he will always have my back and supports me through.

He gives me time to reflect on my achievements and successes before I move on to the next task. This is highly appreciated and it gives me the chance to see where I am growing and where I still need to grow.

At work Steffen is very professional, he understands our business so well and will always have the customers at the front of his mind. He encourages the team to always use facts and not emotions, data quality and assurance is
very important to him.

Last but not least Steffen is a big believer and follower in 'Family comes first, and as a member of his team this is hugely reassuring. He encourages me to take time for me, encourages breaks if I need them and is always around if I need to talk about my mental health. I trust
him!

Steffen is a great team leader, who has a
unique skill to motivate his colleagues, to
satisfy the customer and to drive the
company’s success. Maneuvering in this
Bermuda-triangle is not an easy task and
Steffen is certainly one of the greatest
navigators I met in this regard.

 Jana Trickova

Global Head of Customer Service

I met Steffen while working at Alstom Power /
GE Power Services
And was impressed with his leadership style
from day One. Steffen is a true leader who
always walks the talk.He is someone I and
other team members can trust and rely on. We
always know that we have his back.

His knowledge in the energy business is hard
to find. He has almost 30 years of experience so
his works already speaks for itself. Steffen
thrives in dealing with the challenging
situations, such as a company facing challenging
market conditions or a very large and complex
organisational changes such a merger between
Alstom and GE. Steffen has successfully
implemented many change management
initiatives over the years.With such vast
knowledge in the industry, holder of Six Sigma
certification, being a lean guru, we always had
a confidence that things will be resolved.

He is a problem solver, analytical thinker,
strategist and the most, he is an inspiring
leader. At the core of everything Steffen does
is CUSTOMER. External and Internal. He
managed and successfully completed
hundreds of improvement initiatives that
increased overall business efficiency and
improved customer satisfaction & loyalty.
Steffen has the intellectual horse-power and
determination to get things done...and to make
change stick. For every project, we had a
structured roadmap that helped us to achieve
our goals.


On a personal note, over the years, he became
my mentor who helped me to navigate through
my career and also helped me to complete my
Master Thesis while juggling my full time job.

Additionally, he was a president of GE
Volunteers and drove multiple charitable
events that made a huge positive impact on
people's lives.-I would very highly recommend
Steffen as a great asset to any organisation
that would be lucky enough to have him join.

He was the visionary leader who defined a clear roadmap, built up a multi-disciplinary team, implemented a totally new way of working across global teams and moved everything forward no matter what.

Although the project timeline, we made it happen
under Steffen's leadership, which made us and the company very proud!

business vision and network: I learned and grew a lot with him and would recommend working in his organizations anytime.

 Sherol Streden

Director, boss DYNAMICS

For about six months, I felt stuck in a routine, making little to no progress in my business. Then a connection on LinkedIn introduced me to Steffen from Streamline Formula, who encouraged me to join their 90-day program designed for business leaders.

That decision was a turning point.

Steffen and Edit coached me with dedication and insight for more than 90 days. Steffen helped me develop my personal leadership skills — sharpening my mindset, confidence, and consistency — while Edit focused on refining my business improvement processes. Their combined strengths created the perfect balance for transformation.

Thanks to their mentorship, I was able to set up my business with clarity and take proactive, consistent actions that have helped it thrive. I’m moving forward with renewed purpose and a solid foundation.

I highly recommend this program to any business leader who wants to break through stagnation and elevate their results. Steffen and Edit are a powerful team who truly care about your success.
