Founders & leadership

The people
behind ETRYUM.

ETRYUM was born from integrative medicine, dentistry and business vision coming together. Its founders share one idea: health should be treated as a system, by a team that coordinates around each person.

01 — Where it began

From a pioneering clinic
to a health system.

The story begins at BDS (Biohealth Dental Spain), the clinic Dr Mario Parra and Héctor Blasco founded in Benidorm, which today attracts international patients. There, dentistry is practised with the whole body in mind, not only the mouth.

With Dr Patrick Welter, an integrative physician trained in Switzerland and Germany, that way of working extends to integrative medicine, longevity, sport and physiotherapy. With Ronald Bos as Chairman, the project gains an international outlook. The result is ETRYUM, at the Ciudad Deportiva Camilo Cano in La Nucía.

“Improving yourself is the best way to help others better.”

At ETRYUM he defines the care model, the integration between specialties and the clinical standards.

04 — How we lead ETRYUM

Four commitments.

  1. 01

    Clinical judgement decides

    Decisions about each patient are made by the healthcare professionals, independently.

  2. 02

    A long-term view

    We are building a centre for decades, not for a campaign.

  3. 03

    One team

    Every discipline coordinates around the same person, not in separate departments.

  4. 04

    Rigour, not promises

    Science and evidence before fashion: no miracle promises, no longevity marketing.
