Human difference

What you do makes a difference

As a board member, manager or professional, you should rely on your internal compass. It is important to keep calm and to bring focus for yourself and those around you.  

All this in a world of fast change where information overload poses new challenges and tremendous pressure. This demands quite a bit from you.

Social Connection

Social wellbeing is essential to how we function, both in daily life and at work, and yet loneliness remains a subject no one talks about out loud.

Background

logos groen 1

I am a professional coach. My first coaching credentials provided me with a combination of a no-nonsense practical approach and research-based theories.

I obtained a Masters in Executive Coaching (MSc) at the Hult Ashridge Centre for Executive Coaching near London. In addition, I am an EIA accredited Senior by the European Mentoring & Coaching Council (EMCC).

For over 15 years, I worked as an executive board member at international organisations in professional services, financial services and philanthropy, with a focus on HR and change management. I’m at my best when I’m initiating change, using my knowledge of organisational dynamics, facts and figures and last but not least, people.

'Both my organisation and I have benefitted from Petra's masterful coaching and facilitation. She's knowledgeable, insightful and professional. Her wealth of experience coupled with her high EQ have been a wonderful combination to drive positive change across multiple levels.'

– Nicola Kleyn, Dean Executive Education at RSM Erasmus University and Professor of Corporate Marketing

'I experienced Petra as an excellent trainer and coach. I took her training Stand Your Ground in English, and experienced that my fear of speaking (in English) has disappeared; I am happy to say that I now speak confidently in public. Petra knows how to create a well structured training. She engages the participants in her narrative in a professional, pleasant way, which makes everyone at ease. She is a professional, who knows how to create a nice (and cosy!) atmosphere, and how to surprise people with her observations and perspectives. As far as I am concerned, the training is highly recommended, not only if you lack self-confidence in speaking English in public, but also in public speaking in general - Petra adds some general skills in a very skilfull and natural way. Very nice; thank you Petra!I

– Marcela Perez Pereira, Coördinator Capacity Building bij Oikocredit International

'Petra translates theoretical models into practice in a clear manner. She gives insight into actions and encourages reflection, both to groups as well as individuals. This made me grow and develop in a valuable way.'

Marjolein Diepeveen, Manager Organisation & Development at gro-up

'I attended Petra's training Stand your Ground and now experience that my fear of speaking (in English) has disappeared; I now speak confidently and I am very happy with that. Petra knows how to put down a good, clear structure in the training, takes the participants into her story in a professional, pleasant way where everyone visibly feels very at ease. The training is highly recommended as far as I'm concerned, not only if you lack self-confidence in an English presentation, but also in general - which Petra adds to your baggage very skillfully and imperceptibly.'

– Janine Trompetter,Managing Consultant at Employment Services

'Petra provided my onboarding coaching when starting in a new position. What a luxury to have someone to guide you in this, who hears from what you are saying what you are actually saying and takes you through it in a pleasant way. Petra knows how to lucidly invite you to stand on the balcony when you yourself are fully engaged in the dance. By clearly identifying my own challenges in conversations, I was able to address them constructively when starting in a new position. Very valuable.

Eva de Groot,Manager HR & Organizational Development at 113 Suicide Prevention

When I’m not at work

Nature is my resting place. I like to head out with my camera to take
photographs
, and preferably landscapes.

I see the beauty in the small things as well as in overwhelming landscapes. Similar to coaching, I notice that a landscape offers new views and discoveries each time I take a different vantage point.

“Not a day goes by where you don’t have an impact on the world around you. What you do makes a difference, and you have to decide what difference you want to make.”

Dr Jane Goodall

 

Purpose

Going through life in a self-aware and balanced manner is something worth striving for. That’s easier said than done, speaking from my own experience. Throughout my executive career I’ve experienced first-hand how difficult it is to break the stress cycle of the rat race.

The many assumptions which we hold about ourselves and others can induce stress and keep us away from courageous conversations, growth and innovation, both at work as well as in our private lives. Pressure makes us less effective in collaboration and causes us to lose focus. Stress makes us eat unhealthily and prone to impulsive buying. Others make their way through traffic jams and rush hour while multitasking. This is not how I prefer to live.

Habits add up to large impact on our health, performance and planet, and it’s our responsibility to care of ourselves and our habitat.

I believe that if we are able to observe ourselves and situations from a different vantage point, we will take balanced decisions which will positively contribute to our and others’ wellbeing and habitat.

Working with Petra has been a truly valuable experience. She creates an environment where honest reflection feels natural and productive. Her ability to challenge your thinking, while remaining supportive and professional, encourages real growth and meaningful change. She is a highly skilled coach, but the secret sauce lies in her being a genuine human being who connects authentically and cares deeply about your success.

Met Petra heb ik een hele fijne samenwerking opgebouwd de afgelopen twee jaar. Enerzijds een warme, inlevende sparringpartner die positief kritisch mee denkt, vragen stelt en mij na elk gesprek weer stof tot nadenken geeft en inspireert. Ook hebben we een paar mooie (teamtrainings)programma's ontwikkelt en uitgevoerd. Ook daar zie ik een betrokken collega, het beste voor de deelnemers willen bieden en prikkelende en inspirerende werkvormen bedenken die de deelnemers net wat meer uitdagen in hun persoonlijke- en of teamontwikkeling. Ik ben zeer dankbaar dat Petra op mijn (RedZebra)pad is gekomen.

Super coach. Vanaf het eerste contact een open, persoonlijk en rustig gevoel gehad bij onze interacties. Petra stelt de juiste vragen en benoemt het zoals het is - niet groter (of kleiner). Heel oprecht en daardoor effectief.
