Quadrivas Clinic Rotterdam

My name is Sanne de Haer, born and raised in Rotterdam and mother of two daughters. In my practice, I combine my passion for health with personal guidance. As a Quadrivas Therapist, I help people regain their vitality and balance — both physically and mentally.

My career began with a degree in Child and Adolescent Psychology at the University of Leiden. With great dedication, I worked for many years as a psychologist within a school counseling service, supporting children with learning and developmental challenges. While this work brought me much fulfillment, I noticed that there was less and less room for personal attention and genuine connection — the very elements I consider to be at the heart of good care.

During my search for a new direction in healthcare, I came across Quadrivas Therapy. An information session about the training immediately sparked my interest: the approach and the results resonated deeply with me. I decided to take a new path, enrolled in the training, and in 2019 opened my own practice.

What makes my work so special to me is the combination of physical treatment and personal attention. My background as a psychologist enables me to look beyond the symptoms alone. I see the body as a whole, with healthy circulation playing a central role in overall well-being. Quadrivas Therapy offers a powerful method to activate that recovery.

It is my mission to guide people toward a healthier, more energetic, and more balanced life — in a process where trust, attention, and genuine improvement are central.
