We enable the potential of healthcare.
We take pride in having built RadioOnkologieNetzwerk, Germany’s leading private network of radiotherapy practices. Our 24 radiotherapy clinics are an essential part of local healthcare ecosystems, providing treatments for malign tumor diseases as well as benign diseases such as osteoarthritis. We also operate two diagnostic imaging practices, two outpatient practices specialising in internal medicine and oncology, and a hospital with primary and emergency care.
We are a part of Ergéa Group, a pan-European cancer care and diagnostic imaging platform. By leveraging the expertise and capabilities of our existing operations in Germany and collaborating with our sister companies in other European countries, we are committed to expanding and diversifying the range of services we provide in Germany.

Our group
The Ergéa Group has been formed through acquisitions in the healthcare sector, bringing together companies with distinct and complementary business models and company cultures.
With medical doctors establishing the strategic course for our Board of Directors and Supervisory Committee, Ergéa Group is a physician-led organisation that, by default, places patients and healthcare professionals at the heart of the healthcare system. We chose the name Ergéa to symbolise the patient-centric mindset we share across the group.
Like Western medicine itself, the name Ergéa has Greek roots. In Greek, érgo means 'work', and ygeía means 'health'. The blending of these two words as Ergéa can be roughly translated to "working for health".
This translation captures our ambition to bring better healthcare to the place where it has the most significant impact – at the patient interface. This is where the healthcare system meets the patient to make a difference in each individual’s life.
Our journey
In 2008, radiation therapy specialists Dr. Sandra Röddiger und Dr. Ralf Kurek founded their first radiotherapy practice in Aalen, North Württemberg. This pivotal moment marks the genesis of RadioOnkologieNetzwerk. Building on this foundation, a thriving, physician-led practice network evolved in subsequent years, committed to seamlessly integrating cutting-edge technology, professional expertise, and compassionate care. From the very beginning, creating an inclusive, safe, and inspirational workplace has been a top priority.
RadioOnkologieNetzwerk has has been established on this solid footing, and the company continues to evolve with a forward-looking approach
Here are some key milestones on our journey.
2023
The network grew with the acquisition of Strahlentherapie Pasing close to Munich and opening of Strahlentherapie Sindelfingen close to Stuttgart in 2023.
With the acquisition of RadioChirurgicum CyberKnife® Südwest in Baden-Württemberg, we expand our expertise to robotics and AI technology to provide precise and personalised cancer treatment for the treatment of certain tumour types.
We expand our reach in Germany by acquiring an MVZ in lower Saxony and a radiotherapy practice, Strahlentherapie Leer.
Summit Partners sells its shares to DWS Infrastructure.
We further expand the network in Baden-Württemberg by acquiring Strahlentherapie Horb am Neckar.
We restructure the company as RadioOnkologieNetzwerk GmbH. Summit Partners, an American private equity firm, acquires shares in the company.
