Timmermann Partners
With a wealth of experience in leading companies worldwide, Michael Timmermann has witnessed firsthand the meticulous application of the consulting craft. However, as a psychologist, he identified a crucial aspect that was lacking: the ability to change attitudes and behavior. Recognizing the significant impact this has on business performance indicators and the success of transformations, Michael realized that while the importance of change is acknowledged in strategy consultancies, the ability to truly make a lasting impact is limited, often hindered by their own culture. When he took over the change practice of a consultant network, Michael found himself faced with the challenge of working in a less analytically clean and structured manner. Drawing upon his entrepreneurial experience, he decided to bring his vision of holistic consulting to life, leveraging the full potential of organizations and ensuring sustainable and effective transformations through his expertise in business and change work.
Timmermann Change Communication
"As someone with a creative spirit, my ultimate goal was to create something extraordinary, impact lives, and make a meaningful difference."
"Oh, come on now, stop complaining. You've reached the pinnacle of success."
That statement held true. He had managed prominent advertising agencies, crafted international campaigns, and earned prestigious accolades. However, there was one burning question on his mind: What was it all for? The answer emerged when Sepp Baumeister noticed Timmermann's search for communication professionals. He chose to channel his creative potential towards helping people transform, rather than simply selling to them.
Our mission is to ignite a spark of change within individuals. While advertising agencies focus on advertising, true impactful communication is the realm of storytellers. They weave narratives that inspire people to embrace transformation. And thus, Timmermann Change Communication was born.
Timmermann Architecture & Design
If you are committed to embracing the concept of New Work and aspire to create an office that not only offers employees a functional workspace but also nurtures, motivates, and invigorates them in their work, then you require the support of a specialized architectural firm with a team of architects, New Work experts, and change experts. We are delighted to accompany you throughout the entire process, starting from the design phase to the final implementation. By choosing our unique team, you will benefit from our in-depth knowledge of current trends, our profound understanding of organizational culture, and our extensive experience in developing and executing innovative spatial concepts.
Timmermann Digital
"How can we effectively reach our extensive audience?" "Is it possible to achieve significant change with limited resources?" "Our company is eager to embrace digital transformation. Can you assist us in this endeavor?"
These were the recurring questions posed by our clients, seeking cost-effective solutions with widespread impact. While others may have doubted the feasibility of scaling change, we saw it as a challenge to overcome. After months of brainstorming, a groundbreaking idea emerged: a smartphone-based change app that delivers profound knowledge in a simple and impactful manner. Thus, the Timmermann ChApp was born.
In addition to the transformative ChApp, Timmermann Digital offers a range of other digital change services, including internal organizational change podcasts, videos, and intranet content.
Timmermann Academy
Change processes are learning processes. That's why every change process requires a certain amount of training. We use our methodological and content-related competencies to create customized in-house training programs for our clients - even without a change process, i.e. standalone. The topics are as diverse as our clients, e.g. agility, leadership, teamwork, change, communication or innovation.
Individuals can also take part in our Change Management Professional course "Living Change".
Timmermann Social
At Timmermann Social, we harness our extensive expertise and years of experience to drive impactful change and foster positive transformation for the betterment of humanity.
When asked about his greatest passion within our range of services, our founder Michael Timmermann passionately expresses his unwavering dedication to Timmermann Social, emphasizing his willingness to devote all his time to its endeavors (if only he could!). This particular service line is deeply committed to bringing together influential stakeholders and promoting collaboration on projects aimed at addressing the universal challenges that affect us all.

Michael Timmermann
Founder & CEO, Agile Coach
Profile
With his straightforwardness based on appreciation and coupled with humor, Michael embodies the consulting philosophy of Timmermann.
As a born entrepreneur, he founded his first company, raba.tt GmbH, in the marketing industry during high school. With this venture, he introduced the marketing tool "Coupons" to the German-speaking region. After selling the company, he studied psychology and then learned the tools of a traditional management consultant at McKinsey & Company. Following his role as a Partner for Change Management at a mid-sized management consulting firm, he founded Timmermann Partners. He also acquired the Ellernhof, a seminar and conference center in northern Germany near Hamburg, improved it, and sold it after three years.
Having spent a total of two years in the USA, Canada, and Mexico, he still loves to travel today – preferably to places he can explore through climbing or diving.
Since September 2015, Michael has been enjoying fatherhood with his son Merlin.

Bernd Witzany
Chief Operating Officer
Profile
The theme of change has accompanied Bernd throughout his entire professional career. Whether as a student, employee, consultant, managing director, or as an independent entrepreneur, he has engaged with change as a constant on at least three continents.
After studying economics, he led the SAP/R3 department as a division head in a state-owned enterprise, overseeing the organizational change process. Following a role as a Senior Consultant in SAP/R3, he became the Chief Operating Officer and Director of R&D for a globally operating company with locations in Monaco, Austria, and the USA.
Several company acquisitions and mergers with businesses from Germany, Italy, Canada, and the USA further heightened his interest in and competence for managing change processes. With his own company, he served as managing partner, guiding clients through change processes, and working as CFO in long-term mandates. This period also involved the founding, establishment, and management of a company in the USA, where he holds a stake and serves on the supervisory board.
Bernd brings extensive international experience to the Timmermann Group, combining it with a constant pursuit of social, methodological, and professional development. The Timmermann Group provides the ideal human and professional framework for this.
With the same dedication and curiosity, he has always pursued his hobbies, including 15 years of American football and currently practicing Ju-Jitsu. He enjoys various forms of outdoor activities, embracing almost every sporting challenge. However, his most significant free time commitment now revolves his young son and an adopted canine companion at home.

Lukas Bargel
Associate Partner, Agile Coach
Profile
As a political scientist, Lukas combines the "hard" expertise of an economist and jurist with the "soft" insights of a sociologist and political scientist. Throughout his studies, he was particularly intrigued by the question of how good human interaction can function. For Lukas, this involves not only contemplating theoretical approaches but also taking concrete action and assuming responsibility: for several years, he has been actively involved in supporting families with a migration background.
As an accomplished athlete, Lukas is a determined individual who gets straight to the point. Since he enjoys sharing his passion with others, he found a fitting challenge in competitive dancing. On the dance floor, he not only learned how to optimize his techniques successfully, maintain posture, and steadily work towards a big goal step by step, but also how important harmony, based on constructive-critical openness with others, is for long-term success.
Lukas is someone you can share hearty laughter with, as well as engage in deep conversations. He is an avid train traveler, spending a lot of his free time on the move. During his city trips, he appreciates the peculiarities of different regions and explores not only the "taste" of other cultures over meals with friends.
Professional Background & Education:
- Master of Science in Economics, Humboldt University Berlin
- Bachelor in Political Science, University of Erfurt
- Practical experience at "Magic Gorilla Coaching" in the areas of career, leadership, and business coaching
- Lecturer at the University of Erfurt for modern organizational forms and working methods, as well as Change Management
- Keynote Speaker in the module Research & Intervention of the Master's program in Psychology (Human Performance in Socio-Technical Systems) at TU Dresden

Michael Boberach
Senior Consultant, Agile Coach
Profile
With his straightforwardness based on appreciation and coupled with humor, Michael embodies the consulting philosophy of Timmermann.
As a born entrepreneur, he founded his first company, raba.tt GmbH, in the marketing industry during high school. With this venture, he introduced the marketing tool "Coupons" to the German-speaking region. After selling the company, he studied psychology and then learned the tools of a traditional management consultant at McKinsey & Company. Following his role as a Partner for Change Management at a mid-sized management consulting firm, he founded Timmermann Partners. He also acquired the Ellernhof, a seminar and conference center in northern Germany near Hamburg, improved it, and sold it after three years.
Having spent a total of two years in the USA, Canada, and Mexico, he still loves to travel today – preferably to places he can explore through climbing or diving.
Since September 2015, Michael has been enjoying fatherhood with his son Merlin.

With his straightforwardness based on appreciation and coupled with humor, Michael embodies the consulting philosophy of Timmermann.

Senior Nutcracker
Profile
With his straightforwardness based on appreciation and coupled with humor, Michael embodies the consulting philosophy of Timmermann.
As a born entrepreneur, he founded his first company, raba.tt GmbH, in the marketing industry during high school. With this venture, he introduced the marketing tool "Coupons" to the German-speaking region. After selling the company, he studied psychology and then learned the tools of a traditional management consultant at McKinsey & Company. Following his role as a Partner for Change Management at a mid-sized management consulting firm, he founded Timmermann Partners. He also acquired the Ellernhof, a seminar and conference center in northern Germany near Hamburg, improved it, and sold it after three years.
Having spent a total of two years in the USA, Canada, and Mexico, he still loves to travel today – preferably to places he can explore through climbing or diving.
Since September 2015, Michael has been enjoying fatherhood with his son Merlin.

Our mission statement
Why we do it:
„To help humanity change for the better.“As Steve Jobs famously said, "It is the people who are crazy enough to think they can change the world who actually do." We firmly believe that for this world to truly change, the people in it must change too. Our mission is to inspire individuals to engage with one another in a direct and appreciative manner, fostering personal growth and taking responsibility to make a positive impact. Our goal is not just to feel good, but to cultivate an environment where treating each other with kindness and respect leads to exceptional results, even within a corporate setting.
How we do it:
„With bright minds and open hearts.“Outstanding change management necessitates a blend of intelligence and compassion. It entails skilfully crafting strategies, programs, and concepts while also possessing the social competence and enthusiasm to engage with individuals and drive transformation. This is our daily pursuit.
In our pursuit of excellence in leadership and teamwork, we embrace the fact that mistakes happen. What sets us apart is our commitment to addressing them openly and dedicating ourselves to resolving them with utmost diligence. However, this unwavering focus on improvement can sometimes lead to misunderstandings. Some may expect us to be flawless and never falter, always upholding our values without error. The truth is, our relentless dedication to self-improvement may make it seem like we make more mistakes than other organizations, but in reality, we are thriving. It is important to remember that perfection is an unattainable goal, but our continuous efforts to learn and grow allow us to come close.
We work on our corporate culture intensively and are a transformational learning community. This means we support each other's learning. In concrete terms, you might imagine it like this:
- We give each other appreciative direct feedback on a daily basis as a gift - also from the bottom up
- Everyone conducts a detailed systematic development dialogue with their supervisor at least every 6 months. In between, regular development discussions take place
- We support our team to work on their attitude and behavioral issues in the form of optional coaching processes
- We strive for psychological safety in the team, as fear restricts the scope for action and slows down learning
- We place a lot of value on assuming positive things about each other and dealing with each other in an appreciative and cordial manner
- Authenticity shines through in the way our team members openly express their true emotions and inner thoughts. This level of vulnerability is only achievable because of the strong bonds we share, built on trust and the recognition of our influence as role models for one another
- We also pay attention to the small things with which we inspire and motivate each other, stimulate each other intellectually and respond to each other individually
- The antithesis of our target culture is a purely transactional exchange relationship to maximize our own benefit to the detriment of the other person.
Because we embody this culture ourselves, we have the genuine ability to incorporate it seamlessly into our client projects.
What we do:
„We make change easy - with you."Is change really easy? The truth is, it can be quite challenging. However, we are here to support and guide you every step of the way, making the process as smooth and effortless as possible.
Designing change of any kind, especially attitudes and behavior, is our core competence. We try to bring together, expand, share and use everything the world has to offer in terms of knowledge and experience on the subject.
Ultimately, it is the power of our clients themselves that drives change - every single individual has the ability to transform. That's why we believe in working hand in hand with our clients, fostering a collaborative approach. We understand that simply delivering change doesn't produce lasting results. True change requires a personal commitment to growth and the willingness to address our own mistakes and weaknesses. It's only when we take our journey seriously, yet approach it with a sense of humor, that we unlock the energy and openness needed for successful transformation.
Genuine transformation can be exhausting, requiring a deep understanding of your own shortcomings and a commitment to personal growth. However, true success lies in the ability to infuse seriousness with humor. Our most successful change processes occur when individuals are both earnest about their own growth and open to the power of laughter. This unique synergy of energy and openness naturally unfolds over time, paving the way for remarkable transformations.
