About us
Dr. Nicolae Olaru has run the ON-Thera Zentrum in Munich-Sendling since April 2000.
He is the founder and inventor of the ON-Thera System.
Behind the ON-Thera System stand more than 45 years of research and practical knowledge, developed for people with chronic complaints and for severe cases where treatment options are considered exhausted. Dr. Olaru has looked after top athletes from FC Bayern Munich, the Olympic Games and world championships. With the highest precision, as in elite sport, he has also treated many well-known people: actors, singers, artists and politicians.

Dr. Olaru combines osteo-chiropractic, chirotherapy, rehabilitation and naturopathic methods into an approach of his own: the ON-Thera System. He developed it over many years on precisely the cases considered most difficult – chronic and unexplained complaints, and those where treatment options were considered exhausted.
His aim: to find the cause where others see only the symptom, and to show people a path they can continue on their own after treatment. “Practical for the practice and for self-treatment” is more than a motto here.
Holistic treatment with a system. It begins with a detailed case history and a thorough examination; from these, your personal therapy plan is drawn up. Manual therapy, naturopathic methods, rehabilitation and prevention work together – for holistic treatment of chronic and acute complaints alike.
Individual rehabilitation and prevention programmes build stability, strength and mobility and help to prevent new complaints.
Research. For more than 45 years, project research has accompanied the development of the ON-Thera System – through to a self-developed therapy system and special equipment with patent applications and granted patents.
