AWN CONSULTING LIMITED
AWN Consulting Limited is an Irish private limited company incorporated on 2 February 2000, registered with Ireland’s Companies Registration Office (CRO) under company number 319812. The company’s registry status is active, and its registered office is at the Tecpro Building, Clonshaugh Business & Technology Park, Dublin 17.
AWN Consulting is a multidisciplinary environmental, acoustics and risk-management consultancy. Per its own website, it advises industrial and public-sector clients on building acoustics, environmental impact assessment, air quality and dispersion modelling, noise and vibration, soil, water and ecological assessment, waste management, and process-safety and risk services including COMAH/Seveso compliance. Its client base spans infrastructure, industrial operations, property and construction, data centres, pharmaceutical and biopharmaceutical manufacturing, semiconductor manufacturing, chemical distribution, wind farms and other energy projects. The firm operates from offices in Dublin and Cork and, per its current website, employs more than sixty environmental consultants and engineers alongside field technicians and administrative staff; at the time of its 2020 acquisition (see below), the firm was reported as comprising more than 40 scientists and engineers.
AWN Consulting was founded in 2000 by Terry Donnelly, Dr Fergal Callaghan, Chris Dillworth and Dr Edward Porter, later joined by Teri Hayes, Damian Kelly and Stephen Smyth as senior management. In December 2020, the company was acquired by Trinity Consultants, Inc., a Dallas, Texas-based international environmental, health and safety (EHS), engineering and science consultancy that was at the time a portfolio company of the private-equity firm Levine Leichtman Capital Partners; the acquisition was publicly announced in early January 2021, with the founding management team confirmed to remain in place. AWN Consulting continues to trade under its own name from its existing Dublin base. The company holds ISO 9001, ISO 14001 and ISO 18001 accreditation, per its own website.

Shareholders of AWN Consulting Limited
Zavia’s on-file CRO-derived shareholder data records a single disclosed shareholder for AWN Consulting Limited: TRINITY EHS ENGINEERING & SCIENCE CONSULTANTS IRELAND LIMITED, holding 100% of the company’s issued share capital (1,334 ordinary shares of EUR 1.00 each), as verified at 31 December 2024. This is consistent with AWN’s December 2020 acquisition by Trinity Consultants, Inc., publicly announced in early January 2021 (see Sources), under which AWN became part of the Trinity Consultants group; TRINITY EHS ENGINEERING & SCIENCE CONSULTANTS IRELAND LIMITED (Irish CRO no. 683139) functions as the Irish holding entity through which that group holds AWN, per Zavia’s on-file corporate-linkage data. No indirect or historical shareholders are recorded in the sources reviewed.
Ultimate beneficial ownership
No natural-person ultimate beneficial owner can be identified for AWN Consulting Limited from the sources reviewed. Its disclosed shareholder is itself a corporate entity, and the ownership chain above it leads, per Zavia’s on-file corporate-linkage data, to Trinity Consultants, Inc. (Texas, US), which at the time of AWN’s acquisition was a portfolio company of the private-equity firm Levine Leichtman Capital Partners. Ownership of a private-equity-backed group of this kind is typically dispersed across fund investors rather than held by a single individual, and no source reviewed identifies a specific natural person meeting a beneficial-ownership threshold, so no UBO is reported here rather than assumed.
Data availability
Full for the direct shareholder: the CRO-derived record on file discloses a single 100% corporate shareholder as at 31 December 2024. This profile does not independently re-confirm that filing against a fresh CRO document search, and Irish beneficial-ownership filings (Register of Beneficial Ownership) covering the ultimate private-equity ownership chain above the direct shareholder were not accessible in this research, so ownership above the immediate shareholder level is classified as not public/not found.

Directors and officers of AWN Consulting Limited
The registry snapshot on file for AWN Consulting Limited records ten officer entries in total with the CRO, of which five detailed records are held in Zavia’s on-file data: three active directors and two resigned directors. The three active directors – Terence Donnelly (appointed 6 March 2000), Fergal James Callaghan (appointed 6 March 2000) and Christopher Dilworth (appointed 25 February 2000) – correspond to members of AWN’s founding management team. External reporting on the company’s December 2020 acquisition by Trinity Consultants, Inc. names “Terry Donnelly, Dr Fergal Callaghan [and] Chris Dillworth” among AWN’s founders (note: press sources spell the third name “Dillworth” where the CRO record spells it “Dilworth”) and confirms that AWN’s senior management team, including these individuals, was expected to remain in place after the transaction. Two further officers on file resigned shortly after incorporation: Susan Murray (appointed 2 February 2000, resigned 25 February 2000) and Ciaran Coughlan (appointed 6 March 2000, resigned 23 February 2004). The same external reporting also names Dr Edward Porter, Teri Hayes and Damian Kelly as co-founders/senior management and Stephen Smyth as a later addition to that team; none of these four appear among the five officer records held on file, so their possible directorships could not be independently confirmed from the sources reviewed and they are not listed here as officers. No nationality or country-of-residence information is disclosed for any officer in the sources reviewed; correspondence addresses on file are residential-style addresses as filed with the CRO rather than confirmed places of residence.
Data availability
Partial: only five of the ten officer records held by the CRO for this company are captured in Zavia’s on-file snapshot, so this may not reflect the company’s complete officer history; nationality is not published by the CRO for company directors.
