Balanced individuals and organisation
Do you want to grow in your personal development and make choices that really suit you. And leave the hassle and the associated patterns behind you.
Please contact me for a no-obligation intake.
As a professional coach, I am your thinking and conversation partner. Together we look at the upper and lower layers in your life and you discover which (un)conscious patterns are no longer serving. From there, the direction and space for lasting growth and positive change naturally arise.
Growth with Boom Coaching & Consultancy

Individual coaching
Is there that recurring conflict or do you recognize a pattern in your behavior or communication that bothers you or is not helpful. You want it but something is holding you back. Do you find it difficult to express yourself. Do you have trouble connecting in your relationship?
You just can't seem to make that next step. These are random examples of themes I work on with clients.
As a Professional Certified Coach (PCC) I use methods such as Value Based Transformation, Family Constellations (see the menu above for more information) and Meditative Reflection.
By reflecting on conscious and unconscious beliefs and patterns, thoughts and behavior, we examine the current situation and gain insight into the contribution of you and others, which makes the need for change self-evident.
Boom Coaching stands for lasting change in the growth you desire. By getting to know what was previously invisible, direction and space for lasting growth and positive change that suits you arise.
Depending on the situation and need, the number of coaching sessions varies from 1 to a maximum of 10. In the initial period, there is typically 2 to 3 weeks between sessions and the time between successive sessions becomes longer as the coaching trajectory progresses. Coaching can be focused on both the work environment and the personal environment.

Organization / Team coaching
Is there too much 'hassle' in the workplace? 'Hassle' such as disrupted or reduced cooperation, poor communication, repetitive conflicts or patterns that negatively affect the working atmosphere or results and more of these types of disruptions.
If you want to grow your organization or team and leave the hassle behind, please contact me for a personal intake.
Depending on the need and complexity, there is a choice for short interventions or change processes. The change processes typically vary from 3 to 12 months and are determined by values such as result, safety, self-reflection and responsibility. Our approach is always tailor-made, personal and direct and has a step-by-step plan with a clear structure and interim results. We work simultaneously at team and organizational level and, if necessary, supplemented with individual coaching.
We guide growth in organizations in a result-oriented way by reflecting crystal clear on the current situation and everyone's contribution. There we look at the observable behavior, patterns and mutual communication, also called the upper current. And we also look at emotions, thoughts and beliefs, also called the undercurrent.
With active working methods we create reflection on conscious and unconscious beliefs and patterns, thoughts and behavior. Insight is created into the contribution of you and others, which makes the need for change
becomes self-evident.
With Boom Coaching & Consultancy, lasting change in the desired growth is achieved by translating the introduction to what is invisible into the desired behavior and/or desired cooperation.

Workshops & Training
In 2025 my workshop `Connecting communication for men` will start. This is aimed at men around the theme, communication in your relationship. This workshop is aimed at men who want to learn to communicate better in their relationship. You will learn to indicate your boundaries and needs. You will also learn how to communicate without your emotions taking over in the pattern where communication gets stuck. You will get to know yourself better and discover where your 'hot buttons' come from and how you can deal with them differently.
The material is currently under development and will be available in the second half of 2025. If you are interested, just send me an email.
Growth with Boom Coaching & Consultancy
I provide results-oriented guidance to you or your organization in the intended growth and development by clearly reflecting on the current situation and everyone's contribution.
By reflecting on conscious and unconscious beliefs, patterns, thoughts and behavior we investigate the current situation and gain insight into the contribution of you and others, which makes the need for new behavior self-evident. By getting to know what was previously invisible, direction and space for lasting growth and positive change that suits you arise.

Who is Boom Coaching
I am Harold van Berkel, founder and owner of Boom Coaching & Consultancy. Certified coach under ICF (International Coach Federation) and NOBCO (Dutch Order of Professional Coaches).
As a person and as a coach I am fascinated by why you and I do what we do? What drives us. And how do we contribute to the situation we are in? We are often surprised when we discover what our contribution is and only then does the insight and space for lasting growth and positive change arise. Patterns in our behavior are so self-evident that we are not aware of them. Seeing through and positively transforming the dynamics into known patterns that we maintain both consciously and unconsciously is what fascinates me enormously and what I work on as an individual and team coach.
With 20 years of experience as a senior manager, in the design and improvement of organizations in Asia, America and Europe within a large international high-tech organization, I also speak the business language with the strong need for results. In these twenty years I have seen myself continuously in change where my passion and insight for human behavior with its visible and invisible sides has become increasingly greater.
I am fascinated by what drives you or the organization and why you do what you do.
At appropriate moments we take the time to slow down and take the time to answer the following questions in detail;
Who or what gets priority?
What will the intended change achieve?
And who or what pays the price for that?
I work with what shows itself on the surface and the underlying layer. The combination of the two is necessary for lasting change.
Contact me and share what's going on - I'll share my vision and plan of action with you and together we'll create the growth you want.
In addition to my professional development within the business world as a manager and coach, I have been training Brazilian Jiu-jitsu for over 20 years. I am continuously working on taking another step further in my physical, mental and emotional development. Better able to face any challenge, accept it and be grateful.
As a professionally certified coach, I adhere to codes of conduct that are in the best interest of the client and can be found via this link https://coachingfederation.nl/icf-code-of-ethics/


How did the name "Boom Coaching" come about?
"The tree" is for me a symbol of strength, adaptability, growth and development. The tree, observing without judgement, vulnerable and rock solid, with its great ability to adapt to all seasons stands robustly rooted in the earth with its long strong roots invisible to the eye.
In addition, David Bohm's ideas are a good basis for me as an image to shape relationships with each other and to communicate.
This symbolic meaning of 'de Bohm' is therefore the source of the name "Boom Coaching"
"What is essential is invisible to the eye."
