Just a short mail to say a thank you to QSI for all the help in preparation for our recent ISO 9001 2015 Audit. Thomas Phelan was simply excellent and I know I speak for the rest of the team in saying that, from day 1 his ability and knowledge immediately transferred to the team, which built our confidence and belief that we could achieve the standard required. This was a massive learning curve for myself and some of the team, but Thomas gave us a steer and as a good mentor should, felt part of our team.  Thank you Thomas once again. Finally, I would also like say that we look forward to working with QSI, yourself and Thomas in the future. From, Pat of Lucey Transport.
