What do clients say?

“Maria is a phenomenal coach. She not only helped with “outside” factors such as speaking, communicating, etc., but she also digs deeps and helps you uncover any “inside” factors that block progress. She is organized, structured and effective in her approach. You will get exercises, review those exercise and practice those exercises in real time. I can only recommend her services – you will not regret it! This is the kind of education that any of us can benefit from, regardless of how senior or junior you are in your organization.” – Kim Chen, Program Manager, Internal Innovation, Cisco

I joined Maria’s workshop “Engaging and Involving Your Audience”. It was highly practical, with role plays, filmed exercises or in front of others. Maria knows how to put everybody at ease and creates a very supportive atmosphere. Her observations are spot on and she delivers her advice in a direct and subtle way. We practiced in class and all participants showed amazing improvement by the end. Marias lively personality, professional and artistic background and her overall passion make for truly memorable learning. I can highly recommend her.” Grit Thierfelder, B2B Marketing & Product Management

“The workshop surpassed all my expectations; your expertise and coaching skills were truly impressive!” – Viktor Lolev, Associate Director Client & Market Development, IMD Business School

“The training with Maria was the most effective workshop on communication skills I’ve ever attended – the small group format, personalized feedback, and practical advice offered by Maria made the experience superb! I walked out of the training with a toolbox of very pragmatic, yet simple steps for enhancing my communication style and I keep referring to them in my daily life.” – Denitsa Marinova, Marketing and Communications Coordinator, Business School Lausanne

I worked with Maria for two coaching sessions prior to leaving Lausanne. It was a great experience and I would strongly recommend her as a great coach (or THE coach) in the Vaud area. What I gained from the two sessions: 1. Discovery of my communications baseline through 360 feedback from colleagues 2. Exposure to very practical techniques to increase my presence and communication effectiveness 3. Confidence that progress in communications is real and achievable – and motivation to keep working at it!” – Annabel Tio, Strategist, Consumer Health at Bayer

“On behalf of the team I would like to thank you for hosting this wonderful two day sales pitch workshop!
All of us benefited tremendously from it and we really appreciate the fact that we not only learned theory but that we could practice with cases that are relevant to our work. The tips and feedback you shared were extremely valuable and we will apply them in our pitches moving forward. We truly enjoyed working together!” – Alessandra Price, Associate Sponsorship Manager, ArtBasel

“Maria is a fantastic voice coach with great experience, knowledge and fun to work with.
She helped me prepare big events/conferences and bring my voice to the next level. Through working with her I was able to connect with my own voice in a different way, which gave me confidence,  improved my presence and helped me reach bigger audiences.” – Silke Zanke, Mentor, facilitator and host at

“Fantastic session: I really enjoyed the exercises and the frequent feedback that I received from all classmates. Thank you Maria, unforgettable session, the practice method was really necessary to get the points.” – Manager, Nestlé

Dear Maria, I just wanted to let you know that what we started last year with the pitch we wrote together succeeded today!
We found the right investors and now have the necessary financing to grow the company! Thank you for your great help.” – Simon, CEO at bNovate SA

“Maria has a tremendous ability to very lightly bring the voice one wishes to have, to life. Who knew I didn’t know how to breathe? Now, I do. And that makes everything better. She is enormously perceptive and unfailingly positive and runs a transformational workshop in a spirited and graceful way. I highly recommend you work with Maria to make your voice a tool that springs you forward.”  – Caroline Rennie, Managing partner at ren-new consultancy

“I joined one of the VoxImpact evening workshops, and it was excellent; short, sharp and efficient with hands on techniques I can use right away. You get a better understanding of the under-utilized power of your own voice and how to better take advantage of, and rectify this, as well as tools and techniques that you can practice on at home. The session was highly interactive, with group work and peer feedback which made it into a dynamic ,stress free and fun workshop with immediate ROI. Maria is professional, knowledgeable and excellent at managing the group, as well as giving individual pointers and feedback in an open and constructive manner.”  – Gunnel Berggren, Sales and Marketing Manager at Hôtel des Trois Couronnes

“I enjoyed a personal voice training organised by Maria. Maria has abundant experience and knowledge about the voice. I learnt much from the training that covered from the basic body positioning to a professional presentation. I would recommend Maria to anyone who wish to improve the way of speaking.” – Yoshiko Kurisaki, Executive Consultant on Cross-Cultural Management
