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.

The leadership coaching with you was amazing 🔥🔥🔥
I was skeptical at first, but now I'm grateful 🙏🏻because we have a clear strategy and focused on the right priorities 🎯 that I know my team and I will crush it thanks to you Steffen.

Lawrence Quinn

Managing Partner Emerald Group

During my tenure as President Alstom, Steffen proved to be a world-class asset as one of the key US Executive team members.  Steffen was played a critical role during the nuclear power demand downturn to transform Alstom's 350 million USD Chattanooga investment from a nuclear-centric organization into a competitive gas turbine-centric production facility within 12 months.

Steffen capitalizes on his strength of character and people skills, ability to blend manufacturing expertise with the strategic know how and a no-nonsense approach contributing to making the impossible possible.

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.

Global Parts Operational Excellence Leader

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!

 Roman Strecker

VP People Relations Germany

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 horsepower 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.

Entrepreneur, Urban Retreat

I’ve just come off a coaching call with Steffen, and wow! I’ve been in the NWM business for 3 years. I’ve had a couple of free coaching calls from other coaches, which have been ok but nothing mind blowing per se. This call, however, has literally blown my mind!

Steffen has provided a strategy to grow my business, he has recommended someone who deals with Mindset, helped me to understand how Vision boards help, and this is important, perhaps the most important, he has reignited my passion for helping people, whether it be introducing them to the wonderful products I recommend or, helping them to start their own business to provide for their families during this terrible recession.

Do I recommend him? 10/10
Would I work with him? 10/10
Am I going to implement the strategies he’s suggested? Yes!! 💯

Steffen knows his stuff. He’s easy to talk to, breaks things down to a relatable level and again, most importantly, makes you realize you can make a difference, not just in your own life, in others too! Thank you Steffen

Steffen is a living example of a real Leader, who truely empowers and inspires his team to go extra miles to achieve the goals.

I had the great chance to join his team as a project planner on a complex project for a new Gas Turbine Product Launch. 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!

Steffen is an outstanding mentor and leader. Joining his team, it hit me his ability to build and empower his org as Parts GM to improve on all operations KPIs. He always adapted to the challenges we faced through strong
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.
