Your questions.
Our answers.

Talk to our practice team
Is this covered by health insurance?

We are a private practice and bill transparently under the German fee schedule for physicians (GOÄ). Private health insurance (PKV) and Beihilfe typically reimburse our services. Self-paying patients are equally welcome.

What defines your approach?

We bring together different ways of understanding your body: bloodwork, body composition, strength, mobility and a hands-on examination of your joints and muscles. Your symptoms and goals guide which tests we use. The findings shape a treatment plan for the practice and everyday life: nutrition, training, recovery and targeted supplements where needed. Follow-up appointments review your results, physical function and symptoms together.

How long is a first appointment?

We spend 60 minutes on your history, previous results, goals and a physical examination. Together we decide which further assessments and treatments make sense. We discuss their scope, timing and costs with you; not every test takes place at the first visit. You can upload existing records to the portal beforehand.

Do I need a referral?

No referral is required. Book directly on our website or via Doctolib, or message us if you are unsure which appointment type fits best.

Can I keep seeing my existing doctors?

Yes, absolutely. We are happy to work alongside your existing doctors and specialists, especially when coordination or a second perspective is helpful.

Can I be treated in English?

Yes. Appointments with us are fully available in German or English; just tell us your preference when booking.

What's the fastest way to reach you?

You can reach our practice team by WhatsApp or phone at +49 152 33520967. Book your initial consultation directly on our website or via Doctolib.
