Tetra Tech Group Ireland LIMITED
Tetra Tech Group Ireland LIMITED is a Private limited company (Ltd.) registered in Ireland under IE091911, and its current status with Companies Registration Office (CRO) is active. The company was incorporated on 9 November 1982 and lists its registered address as DUN LAOGHAIRE CO. DUBLIN, Ireland. 1 shareholder is on record for Tetra Tech Group Ireland 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 30 September 2026.

Officers
5
One of the 5 officer records shown for Tetra Tech Group Ireland LIMITED is a current appointment, filed with Companies Registration Office (CRO). JOHN SHALLOE (appointed 2013-02-12) serves as Director. The remaining 4 records shown (JAMES TIMOTHY DORAN, PETER DOWEN and 2 others) are former appointments that have since been resigned.
The register reports 29 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at Tetra Tech Group Ireland LIMITED sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
Tetra Tech Group Ireland LIMITED sits 4 levels below its ultimate parent, Tetra Tech, Inc., registered in United States. 2 subsidiaries are recorded beneath it, across 1 jurisdiction. Immediately above Tetra Tech Group Ireland LIMITED is RPS ENVIRONMENTAL CONSULTANCY LIMITED, holding 100% as filed in Tetra Tech Group Ireland LIMITED's own shareholder record with Companies Registration Office (CRO). Tetra Tech, Inc. sits further up the chain, a link derived by walking shareholder filings across jurisdictions rather than stated in a single document. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 2 subsidiaries span Ireland jurisdiction, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear.
