Mediation Profile

Cross-border business and workplace mediator located in Rotterdam and Amsterdam The Netherlands.

Founding partner of The ACADEMY of Legal Mediation and Negotiation (mediation and negotiation training) and Mundi Mediatores ('broker' to match companies and lawyers with mediators). Mundi Mediatores is a reliable cross-border service that can match parties with the most suitable mediators for each individual case taking into consideration the disputants’ specific procedural and outcome-oriented needs. It is also offers state of the art dispute resolution process design:

I have been a business mediator for more than 25 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 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 my website:

Mixed-style business mediator. Manon Schonewille uses an outcome-focused and varied style of mediation that is adapted to the party's 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 diverse approach, depending on the topic, dispute and needs of the participants 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 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.
