A few pictures from our recent team day (& night!) in Dublin City. A great day where we welcomed some of the OEM Sweden team also.
We recently had an incredible team building day at Croke Park where we had inspirational talks from Mark Donovan and also Niall Breslin, who talked about the excellent work his charity A Lust For Life.
Our partners and friends from OEM Automatic AB Sweden attended also. Great to show them a piece of Irish history.
