NATIONAL PROTON THERAPY CENTRE LIMITED
NATIONAL PROTON THERAPY CENTRE LIMITED is a Private limited company (Ltd.) registered in Ireland under IE670990, and its current status with Companies Registration Office (CRO) is intermediate. The company was incorporated on 22 May 2020 and lists its registered address as KILQUADE,WICKLOW, Ireland. 1 shareholder is on record for NATIONAL PROTON THERAPY CENTRE LIMITED, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Companies Registration Office (CRO) and was last updated on 22 October 2026.
