About me

Human behavior expert and ocean lover

My name is Greetje Kooistra and I was born in the Netherlands. I currently reside on Bonaire, a small island located in the Dutch Caribbean. Since I was a child, I have had a passion for water and have always recognized its healing properties.


One experience that taught me the healing effects of water was when my mother was going through a difficult time. I was only 5 years old and I suggested that she go swimming every morning, and it made her day better.


As a result of my love for water, I became a certified swimming teacher with various specializations. I offered swimming lessons to people of all ages, including children, adults, the elderly, mothers with children, and people with disabilities.


Along with teaching swimming, I developed skills as a behavioral expert, trainer, and coach. My area of expertise includes stress reduction, conflict management, personal development, career coaching, and dealing with aggression.


My passion for water and personal development led me to Aqua Relax, where I can support my clients' journey toward balance and relaxation through the healing qualities of water.


Currently, I work part-time as a coach and trainer. I also offer Aqua Relax sessions to my clients.
