😊 McMahons were delighted to partner with Portwest Ireland recently to sponsor branded hi-vis vests for the 5th Athy Beavers Club.

Our Group Engineering Manager, Matt Keogh, has been involved with 5th Athy for many years. When he mentioned that the kids were often wearing oversized hi-vis vests, we were delighted to step in and help provide vests that fit!

👏 A big thank you to Portwest for their continued support and for helping us support the local community.

🕰️ A glimpse into the McMahons history

This photograph shows employees at the James McMahon Timberyard on Alphonsus Street, Limerick, dating back to the 1930s.

Our roots in the timber trade go back generations, and this photo offers a glimpse at some of the people who helped shape McMahons in its early days. From timberyard to builders' providers, our commitment to serving the building and trade community has continued throughout the years.

👀 Do you recognise any of the faces? We’d love to hear from you if you have any information about the people pictured or any other connection to the timberyard.
