„25 years in, I love what I do even more than when I started.“

Andrea Birte Schüller

A business psychologist by education, I spent the last 25 years doing the same thing: supporting individuals, teams and organisations to become an even better version of themselves – and I still can’t imagine doing anything more exciting, or more rewarding.

The majority of my time is dedicated to designing and delivering bespoke leadership development programmes that accelerate individual and organisational growth.  They are targeted at high potentials in international professional services firms and corporations who are being groomed for broader leadership responsibilities. I started out as a consultant, being involved in large scale change projects that ranged from the creation and implementation of a new sales philosophy to supporting organisations through restructures and mergers/acquisitions.

I set up my own consulting, coaching and action learning business in 1998 before co-founding Toguna Leadership in 2014 to promote a truly enabling leadership style: it focuses on talking at eye level, seeing individuals rather than judging them and inducing a deep rooted growth mind-set.

We firmly believe that knowledge-driven organisations with Toguna Leaders at the helm will thrive – as the professionals working with them are free to think for themselves, keen share their ideas and truly invested in their organisation.

As an Executive Fellow of a leading UK Business School I also keep abreast of new developments in the academic world.

I am an accredited executive coach and hold a UK MSc in Coaching and Behavioural Change alongside my German MSc in Psychology. I regularly train aspiring coaches and leaders who would like to develop a coaching style.  My own academic research focuses on how to drive change through leadership development programmes.

Having grown up in Japan and Pakistan I delight in working internationally. As an adult  I spent very happy years living and working in the UK and find any excuse to go back. 80% of my work is delivered in English to international groups. My corporate work currently focuses Eastern Europe, Asia and Latin America.

I live in a small hamlet just outside of Munich. My teenage daughter is in the final year of her International Baccalaureate – and about to hotfoot it out of Bavaria. Germany didn’t even make it onto the university locations shortlist – another excuse for me to travel more.

„Helping fantastic people grow – what a job!

Martina Weinberger

I started my career in Marketing and Strategy Consulting, but have spent the last 16 years working with leaders of all kinds, observing them and the environment they work in grow and flourish– which is fun and fulfilling for me too!

The majority of my work is designing, delivering and improving bespoke leadership development programmes for international corporate clients and working with individual leaders in coaching. I relish the buzz of real-time interaction with others – creating the energy and space that groups and individuals need for their learning.

I hold an MBA from INSEAD and a BA in European Business Administration. I am certified as a systemic business coach, accredited with the DVCT – German Association for Coaching and Training as well as with the Association for Professional Executive Coaching & Supervision ( I am certified in a wide range of training courses, amongst others Crucial Conversations by Vital Smarts, Tools of Engagement by the Pro Group, «ZRM®»-Trainer (Zurich Resource Model) by ISMZ, MBTI Step1 and Step2 and Science of happiness at work by Iopener. I also greatly enjoy being part of the community – a group of great professionals mainly in the US but working world-wide.

I lived and worked in Portugal, France, the UK and the US, as well as my native Germany. In the course of my international life, I met my French husband and we are very proud parents of three teenage children.

Can a blind person ride a motorcycle? Yes, if someone lends their eyes (and a scooter). In 1992 a blind listener of my radio show told me about his greatest regret being visually handicapped. He would never be able to ride a motorbike. That touched me. We drove the old Munich airport where I let him drive my Vespa on an empty runway. I sat behind him, making sure we would not land in a ditch. – This is how I work today as a Trainer. I encourage participants to try new things, making sure leaving the comfort zone for them is a positive experience. After 30+ years on stage as a musician, actor, moderator, journalist, facilitator or keynote speaker I know how to reach and touch an audience.

My original background is music. I played in a band and wanted to be a pop star. Instead I became a radio and television host. In my 25 years in the media industry I hosted thousands of live shows and hundreds of corporate events and political panel discussions. As a certified trainer I helped managers in 12 countries to unleash their communication potential. I’m an expert in Story Telling, Body Language, Presentation and Leadership Communication. My passion: see people grow.

I have twenty-five years experience in leadership, performance and organisation development. I have held global and European positions in large internationals and have worked in Europe, the US and Asia.

My works includes: the design and delivery of leadership development programmes; assessment and development of the top 100-300 leaders in an organisation, to support them in delivering new business strategies; and coaching leaders from a diverse range of international businesses.

I consider it a privilege to work with very talented people, and find a joy in seeing them further develop and increase their performance.

I hold an MBA (with distinction) from the City University Business School, and a dual honours degree in Marketing and German. I am accredited as a Full Member (advanced level) of the Worldwide Association of Business Coaches.

I always wanted to work with people and see the world. Where best to do this? For me it was in the hotel business, working in Germany, England, Switzerland and on a cruise liner. What a great experience this was! After several years in various five Star Hotels, I joined the sales and marketing team of Disneyland Paris, based in Germany, which turned out to be an intensive learning journey in how to get different cultures working together, being part of a global team, working for an US company that had just opened in France. After celebrating the 5th anniversary of Disneyland Paris I moved on to the Irish Tourist Board and until today still feel very close to Ireland and the Irish people.

During my time promoting Germany in the German Tourist Board Paris, I was not only able to fully experience the French “savoir vivre”, but it was also the perfect opportunity to get my French finally to the level, that I had always wanted it to be. For the last ten years I have been working for a premium German car manufacturer, training our global staff and partners in how to best deliver outstanding customer orientation and how to represent a premium brand. Working in the automobile industry is a fascinating indeed in these fast changing days.

The bulk of my work today is continuously enhancing the global in-house training and development programmes, training trainers and delivering trainings myself.

Beyond this, I am also an accredited Business Coach and certified trainer (Chamber of Industry and Commerce in Germany.

I thrive on real time interaction with others, creating the platform of trust that groups and individuals need to learn. I strongly subscribe to a solution focused approach. The starting point being the intended positive outcome, I see this as vital in times where change and cross functional work are buzzwords and where the day-to-day impact of new ways of working stress many people and keep them from engaging with all their energy and potential. Joining the Toguna Leadership team gives me the opportunity to work with a group of great people, sharing the same values, with whom I can focus on enabling teams and their leaders to address the issues of the future, focussing on solutions and making the most of their existing strengths and resources.

My French husband and I are proud parents of two teenage kids, with Munich being our home base.
