ON·THERA
A different way of treating.
Back, neck, chronic pain – here your way back into movement begins.
ON-Thera is an institute for therapy & prevention. We treat people with chronic, unclear or already “given-up-on” complaints – cause-based, holistic and risk-free. Not managing symptoms, but a real path back to health.

Many come to us when other paths have long since ended.
Years of back pain. Headaches with no explanation. Examinations with no findings. Anyone who has already tried a great deal is in the right place here: we listen, look closely and search for the actual cause – where others have stopped.
- Chronic back & neck complaints
- Headaches & migraine rooted in the spine
- Unclear, “given-up-on” cases without a clear diagnosis
- A wish for prevention instead of endless repair

Practice in motion · Munich-Sendling
Four principles, one goal: solving the cause.
“A different way of treating” is not a slogan but a method. Dr. Nicolae Olaru developed his own system out of years of experience — for people no one had been able to help.
Cause, not symptom
We don't just ask where it hurts — but why. Only once the cause is clear do we treat it in a targeted way.
Holistic & natural
Natural, traditional and modern methods — cleverly combined into a path that suits the whole person.
Risk-free & gentle
Gentle, well-tolerated treatment without unnecessary risks, tailored individually to you and your body.
Practical for self-treatment
You don't stay dependent: we show you how to maintain your progress yourself at home.
A spectrum that targets the cause
From the thorough initial assessment through the targeted spinal treatment to guidance for home – every service is a building block of your personal healing plan.

Calm, bright, in the heart of Sendling




People for whom other paths ended
„I had chronic back pain that led to constant headaches. After just 2 sessions the pain had completely gone — and that was a year ago now. An honest and very friendly man.“
„After years of back problems I am finally pain-free here. The personal care has given me new courage for life. I can recommend this practice to anyone suffering from back pain!“
„Because of my chronic head and back pain my husband recommended the ON-Thera practice in Munich. He and a colleague had been successfully treated there themselves. After other therapies had failed, I came here.“
„My sister and I finally found this practice after years of suffering and unsuccessful treatments. After a thorough examination we received excellent advice. Thanks to Dr. Olaru's skill we have finally reached our goal.“
