Handlers
Marc van Leeuwen graduated from the International Academy of Osteopathy (I.A.O.) and earned the Master of Science degree in Osteopathic Medicine (Msc. Ost. Med.) through Bucks New University (UK) in 2020. Before that, he worked as a Manual Therapist and Sports Physical Therapist (MSc) for over ten years. In 2022, he completed the specialization ‘Osteopathy in Children‘. This two-year training provided him with much knowledge and new insights into examining and treating children and newborns. As of 2023, Marc is an instructor at PRO Osteo and teaches within the course “Osteopathy in Children. He also travels regularly to England to take courses at the Sutherland Cranial College of Osteopathy (SCCO).
Every day, he works with great enthusiasm and passion to achieve the best possible outcome together with the patient. As an osteopath, he sees people with a wide variety of complaints. He treats infants and children as well as adults; athletes and non-athletes.
What fascinates him, among other things, is the relationship of the various tissues and body systems within the human body. The body is a whole and everything works and moves together. Knowing this connection and recognizing its importance ensure that the osteopath always looks for the cause behind a complaint. Marc also sees finding the cause as a major challenge. Because he knows that only there can optimal results be achieved. He is therefore very grateful for the daily cooperation with his experienced companion Ton van der Heiden. Marc has since been able to implement the unique method of examination within his own osteopathic research.

Sten has been affiliated with Andromeda Centrum voor Osteopathie since 2024. In the same year, he completed his training at the International Academy of Osteopathy (I.A.O.) and obtained his Master of Science at Bucks New University (UK). Before that, he worked as a physiotherapist for seven years. During this period, he discovered that some complaints remained persistent and difficult to explain. His curiosity and the need for a broader view of health brought him to osteopathy. The holistic approach to people, with a focus on supporting the body’s self-healing capacity, gave him the knowledge and skills he was looking for.
As an osteopath, Sten looks beyond the complaint alone. He looks for possible disruptions and mutual connections in the body that can contribute to the development or maintenance of complaints. He likes to actively involve his patients in the treatment process by providing insight into the origin of their complaints. His friendly, calm and analytical approach ensures that you as a patient feel heard and understood.
Sten continues to develop within his profession. He is currently specializing in osteopathy for babies and children. A logical next step, given his experience and interest in this target group. He has also fully integrated the research method, which was developed by osteopath and former colleague Ton van der Heiden, into his approach. This makes his treatments both personal and effective, for both acute and chronic complaints.
Ton van der Heiden has been practicing as an osteopath since 2002, graduating from the International Academy of Osteopathy (I.A.O.) in Ghent, Belgium. Before that, he worked as a physical/manual therapist for more than 20 years.
Osteopathy has since brought him and his patients much. Not only has this training provided increased knowledge, it has also laid the groundwork for a special way of examining the patient.
His colleague Peter van Dommelen and he developed a completely new method of research and they added it to the already existing research techniques. This led to a wealth of information and new insights. They then set up a course, giving fellow osteopaths the opportunity to also apply this approach.
Every day he uses this method of examination and patients can reap the benefits. For more information, please visit our site under the “publications” heading. As an osteopath, he is always looking for the cause of a complaint. This method of examination allows direct action to be taken on the structure, where the core of the current problem lies, and the number of treatments can be limited.
