Mediation Profile

Business and workplace mediator located in Rotterdam and Amsterdam The Netherlands.

I have been a business mediator for more than 20 years. When I started my career as a young dedicated company lawyer in the 1980’s, a client once told me: ‘Thanks but this legal approach doesn’t make sense, I will solve it in a commercial way.’ At the time I didn't know what to make of it. However questioning what is truly driving your client and how to serve them best vs. a purely legal mindset probably influenced my decision for a career switch to become a marketing manager at companies like Schering, Nestle and Guhl.

Being in charge of an international department I was often asked to negotiate (I did not know the term 'mediation' yet at the time) between the international head office, subsidiaries, colleagues, clients or competitors. Another key moment was when in the mid 1990’s somebody told me ‘There are people who make a living out of this, it’s called mediation.’ I was immediately motivated to follow several mediation and negotiation courses including the PON at Harvard law school in Boston.
Ever since my business is about making, saving or ending deals, combined with my passion to teach others how to do that as well and publishing regularly. Enabling clients to successfully close deals: faster and easier to implement.

I can support you or your clients through the life cycle of deals and collaborations. Making a deal as a deal facilitator or negotiation coach and saving or carefully ending a deal, employment contract or partnership as a mediator.
I can also help others to become a mediator or a better negotiator. As a trainer I'm specialised in training professionals in the advanced use of mediation and negotiation techniques.
Examples of my work are in the attached profile.

I love what I do and if you are looking for a mediator or want to learn more about mediation and negotiation tactics and techniques or what taking a different approach in your work can do for you, please E-mail me: A discovery call or enjoying a nice cup of coffee to see if we are a good fit to work together is free.

Mixed-style business mediator. Manon Schonewille uses an outcome-focused and varied style of mediation that is adapted to the parties needs particularly in cultural disputes. Manon supports the parties and their legal counsel to prepare for the mediation and to design the process steps before the mediation meetings start. During the mediation she clearly manages the process aspects and uses a varied approach regarding the substantive issues depending on the topic, dispute and needs of the parties involved. She has superior communication skills and quickly establishes a trust-based working relationship with the participants. She uses her creative mediation style to guide parties to find new solutions and reach a sustainable outcome.
Parties often comment that she is quickly builds rapport and is flexible. Discovering mutualities, developing creative solutions and finding ways to expand the pie are emphasised. Besides this, the implementation stage and 'workability' of the mediation outcome is given attention.
