Have you ever been in a meeting where everyone knows something's off, but no one addresses it? Deadlines pile up, communication breaks down, and progress stalls...

Over my 15+ years at Deutsche Telekom, I've seen even the best teams struggle—not because the work is too hard, but because the right conversations aren't happening.

I've been in those moments of unspoken tension when competing priorities overwhelm teams, and projects slow down—not due to complexity but because we weren't aligned.

𝗪𝗵𝗲𝗻 𝘁𝗲𝗮𝗺𝘀 𝗰𝗼𝗺𝗺𝘂𝗻𝗶𝗰𝗮𝘁𝗲 𝗼𝗽𝗲𝗻𝗹𝘆, 𝗶𝗱𝗲𝗮𝘀 𝗳𝗹𝗼𝘄, 𝗰𝗼𝗹𝗹𝗮𝗯𝗼𝗿𝗮𝘁𝗶𝗼𝗻 𝗱𝗲𝗲𝗽𝗲𝗻𝘀, 𝗮𝗻𝗱 𝗿𝗲𝘀𝘂𝗹𝘁𝘀 𝗳𝗼𝗹𝗹𝗼𝘄.

By the way—one more "synergy" training isn't the answer!

𝗧𝗵𝗮𝘁'𝘀 𝘄𝗵𝗲𝗿𝗲 𝗜 𝗰𝗼𝗺𝗲 𝗶𝗻.

I facilitate practical, hands-on workshops that spark open conversations, build trust, and foster collaboration. I take pride in helping teams work through challenges and achieve more in a short time than they ever expected.

How I Help:

• 𝗔𝗰𝘁𝗶𝗼𝗻, 𝗡𝗼𝘁 𝗧𝗵𝗲𝗼𝗿𝗶𝗲𝘀: I guide your team through real problems, creating practical solutions.

• 𝗧𝗮𝗶𝗹𝗼𝗿𝗲𝗱 𝗪𝗼𝗿𝗸𝘀𝗵𝗼𝗽𝘀: Every team is unique. I design sessions specifically for your needs, whether it's trust-building, accountability, creativity, or problem-solving.

• 𝗣𝗿𝗼𝘃𝗲𝗻 𝗧𝗼𝗼𝗹𝘀: I leverage LEGO® Serious Play®, Design Thinking, and other methods — but the focus is always on results, not just the tools.

• 𝗦𝘂𝘀𝘁𝗮𝗶𝗻𝗮𝗯𝗹𝗲 𝗖𝗵𝗮𝗻𝗴𝗲: I'm all about long-term improvement, not just quick fixes.

• 𝗥𝗲𝘀𝘂𝗹𝘁𝘀-𝗗𝗿𝗶𝘃𝗲𝗻 𝗙𝘂𝗻: If you want a fun LEGO playing event that's cool, but I can't help you with that —my workshops are focused on solving real challenges. Fun is the result of the hard work.

Alongside my role at Deutsche Telekom, where I build innovative products with partners, I'm excited to offer my facilitation expertise to new teams outside the company.

Let's connect!

I'm currently offering 𝗙𝗥𝗘𝗘 𝗟𝗘𝗚𝗢® 𝗦𝗲𝗿𝗶𝗼𝘂𝘀 𝗣𝗹𝗮𝘆® workshops for tech teams looking to boost collaboration—no risk, just real, measurable results.

Why free? 

While I’ve sharpened my skills internally, I’m eager to work with new teams and gain fresh perspectives outside the company. This is a no-risk way for you to try a proven approach that delivers results and for me to meet diverse, high-impact teams.

Interested?
