Alexianer GmbH
About Alexianer GmbH
Alexianer GmbH is registered with the commercial register of the Amtsgericht (local court) Münster under HRB 2547, with its registered office at Alexianerweg 9, 48163 Münster, Germany. The register extract reviewed for this profile lists the company as active.
Alexianer GmbH is the central holding and administrative company of a Catholic-sponsored group of hospitals, psychiatric clinics, medical care centres, senior-care homes and disability-support services operating in several German federal states, including North Rhine-Westphalia, Berlin, Brandenburg and Rhineland-Palatinate. The group traces its charitable mission to the Alexian Brothers (Alexianerbrüder), a Catholic religious order active in healthcare and social care since the medieval period; the group’s own communications describe more than 800 years of continuous involvement in care for the sick and vulnerable. The modern legal entity is distinct from that centuries-old religious history: it is a corporate structure created to hold and administer the order’s healthcare and social-care operations.
Public commercial-register data (Northdata, drawing on Amtsgericht Münster filings) shows the HRB 2547 legal entity on file since 23 January 2004, initially under an earlier company name, before later being renamed. Alexianer’s own materials describe April 2009 as the point at which the current group holding structure was formed through the merger of previously separate Alexianer carrier organisations. Because these two accounts describe different stages of the same entity’s history rather than a single unambiguous “founding date,” and because the register field held in Zavia’s database for this profile does not match either external account, no single incorporation date is asserted here; readers requiring a definitive date should consult the current Handelsregister extract directly.
The company is registered as an ordinary GmbH (Gesellschaft mit beschränkter Haftung), not as a gGmbH (charitable GmbH), based on the Amtsgericht Münster register data and independent secondary confirmation. This distinguishes it from a number of its own operating subsidiaries, several of which are separately registered as gGmbH entities in their own right.
As a group holding company, Alexianer GmbH itself does not directly operate patient-facing services; these are carried out by its subsidiary hospital, clinic, care-home and service companies (covered in the group-structure section of this profile). At group level, Alexianer reports approximately 34,000 employees across more than 200 professions, around 29 hospitals and more than 80 senior-care facilities, and group revenue of approximately €2.3 billion for the 2024 financial year, according to the company’s own published figures. These figures describe the consolidated Alexianer group and should not be read as the standalone financial results of Alexianer GmbH as a single legal entity, which have not been independently verified for this profile.

Shareholders of Alexianer GmbH
The commercial-register extract reviewed for this profile discloses two shareholders in Alexianer GmbH, with holdings verified as of 4 September 2026:
- Stiftung der Alexianerbrüder (Foundation of the Alexian Brothers) – approximately 94.2% of registered share capital (nominal value approx. €4,149,650 of total registered capital of approx. €4,405,297).
- Aachener Aktiengesellschaft zur Unterstützung hilfsbedürftiger Personen (a charitable Aachen-registered stock corporation) – approximately 5.8% of registered share capital (nominal value approx. €255,647).
Both interests are recorded as direct holdings of ordinary share capital; the register data does not distinguish separate share classes or voting-only instruments. No further indirect chain above these two holders is disclosed in the register data reviewed.
Ultimate beneficial ownership
No natural person is identified as an ultimate beneficial owner of Alexianer GmbH in the sources reviewed for this profile. Control instead rests with an ecclesiastical foundation: the Stiftung der Alexianerbrüder was established on 31 January 2013 in Münster as a foundation under civil law recognised by the Diocese of Münster, and according to the foundation’s own account it took over “the former shareholder role of the [Alexianer Brothers religious] order” in Alexianer GmbH at that time. The foundation’s stated purpose is to preserve and promote the spiritual, cultural and social work of the Alexianer Brothers order and to exercise the associated shareholder functions, rather than to generate returns for private individuals. The minority shareholder, the Aachener Aktiengesellschaft zur Unterstützung hilfsbedürftiger Personen, is itself a charitable entity whose registered purpose is to support religious orders and charitable health and care institutions linked to the Alexianer Brothers Community in Aachen.
Because ownership sits with these two charitable/ecclesiastical bodies rather than with an identifiable natural person, this profile does not assign a percentage-based natural-person UBO. No Transparenzregister (German beneficial-ownership register) extract was reviewed for this profile; readers requiring a formal beneficial-ownership determination should consult that register directly.
Data availability
Shareholder disclosure for this entity is full at the level of direct shareholders, since German commercial-register filings require disclosure of the shareholder list for a GmbH. No natural-person UBO was found in the sources reviewed; this reflects the entity’s ownership by charitable/ecclesiastical bodies rather than a gap in available disclosure.

Officers
20
Directors and officers of Alexianer GmbH
The commercial-register data reviewed for this profile (synced 8 September 2026) contains 20 officer records, corresponding to at least 18 distinct individuals; two people – a Managing Director and one other officer – each appear under two separate appointment records reflecting successive appointments. Of these, 9 records are marked active and 11 are marked resigned, historical entries dating back to 2004.
Among the active records, two people hold the legal role of Geschäftsführer (Managing Director): Erika Tertilt and Dr. Christian von Klitzing. Alexianer’s own leadership page and independent trade-press coverage confirm both as current members of the company’s three-person Hauptgeschäftsführung (chief executive team), with Ms Tertilt responsible for group-level finance and Dr. von Klitzing responsible for somatic medicine, psychiatry, nursing, communications and consulting.
The remaining eight active records carry the more general role of “Officer”: Benjamin Koch, Gilbert Aldejohann, Martin Minten, Katja Steinkühler, Björn Hoffmann, Thomas Wüstner, Thomas Clausing and Stephan Dransfeld. Trade-press reporting confirms that seven of these eight – all except Katja Steinkühler – were granted Prokura (a limited German statutory power of attorney to represent the company) as part of a strengthening of the extended management tier; Katja Steinkühler’s specific function was not confirmed in the sources reviewed.
Only birth year and month are disclosed for each officer, consistent with German register practice; full dates of birth are not published and are not reproduced here. Nationality is not disclosed in the register data reviewed, and it has not been inferred from names, addresses or country of residence; all listed officers show Germany as their address country only, which is a correspondence-address field and not evidence of nationality. Officer addresses in the source data are incomplete (no street, locality or postal code recorded) and are not reproduced individually.
Recent officer changes
- 1 November 2025 – Frank Thörner-Tamm joined Alexianer as a third Hauptgeschäftsführer, with responsibility for group-level human resources. This appointment was reported by Alexianer’s own communications and by trade press but was not present in the register data reviewed for this profile, which may not yet reflect this filing.
- June 2025 – Sascha John left Alexianer’s Hauptgeschäftsführung at his own request; he does not appear in the register data reviewed for this profile.
- Register-recorded resignation – Karsten Honsel, appointed Managing Director on 19 May 2021, is recorded in the register data as resigned; external register-derived sources place the effective removal in August 2023.
Data availability
Officer disclosure for this entity is full for appointment and resignation events at the level of the German commercial register, but the specific snapshot reviewed for this profile appears to lag at least one confirmed 2025 leadership change. Nationality is not disclosed by the register and is stated here as not disclosed rather than inferred.

Group Structure
Group structure of Alexianer GmbH
Alexianer GmbH is not an independent company; it is the holding company of a large, verified corporate group and is itself controlled by the Stiftung der Alexianerbrüder (holding approximately 94.2% of its share capital, see the shareholders section of this profile) and by the Aachener Aktiengesellschaft zur Unterstützung hilfsbedürftiger Personen (approximately 5.8%).
Below Alexianer GmbH, the corporate-linkage data reviewed for this profile (dated 8 September 2026) records 21 direct subsidiaries and a further 72 indirect subsidiaries across up to three additional tiers, for 93 verified subsidiary entities in total. Almost all are separately registered German companies (mostly GmbH, with a number of gGmbH charitable entities among them) operating hospitals, psychiatric clinics, medical care centres (Medizinische Versorgungszentren), senior-care and residential-care homes, disability-support services, and shared internal service companies (for example IT, HR, facility and logistics services). The entities in the group are registered chiefly with the commercial registers of Münster, Köln, Düsseldorf, Wuppertal, Aachen, Berlin-Charlottenburg, Potsdam, Krefeld, Siegburg, Montabaur, Koblenz, Steinfurt and Coesfeld, indicating operations concentrated in North Rhine-Westphalia, Berlin, Brandenburg and Rhineland-Palatinate.
Ownership percentages between Alexianer GmbH and its individual subsidiaries are not disclosed in the corporate-linkage data reviewed; this profile therefore does not assume 100% ownership of any subsidiary and reports these as verified corporate relationships without a stated ownership percentage.

Recent structural changes
Bethlehem Gesundheitszentrum Stolberg GmbH and its subsidiaries appear in the current group tree as a direct subsidiary of Alexianer GmbH.

Corporate-linkage information for this entity is assessed as partial: the parent and a large number of subsidiary entities are verified by name, jurisdiction and registration number, but ownership percentages between Alexianer GmbH and individual subsidiaries, and between intermediate subsidiaries themselves, are not disclosed in the data reviewed.
