We challenge you to find a better group of guys!

Ryan Williams

Ryan began his career as a school-based apprentice with GHC in 2013 and completed his Certificate III in Carpentry under Guy's meticulous training. He was nominated for the 2017 Master Builders' Apprentice of the Year and his commitment to his trade and unfailing work ethic are to be commended.

Don't be fooled by Ryan's light-hearted humour and jovial nature - he's serious about what he does and has the skill to back him.

Ryan has recently become a father and he and his wife, Eden are enjoying this new phase of life with little Rowan.

Ryan is one of our highly valued site supervisors and is a terrific leader and friend to those he works with.

James Rowley

James is a skilled and dependable member of the GHC team, known for his calm, thoughtful approach on-site.

He began his working life in the Australian Army, gaining valuable discipline and teamwork skills. Eventually, he discovered his passion for construction and began a carpentry apprenticeship with a builder in Warwick.

James joined GHC at the beginning of 2025, and we’re thrilled to have him as part of our crew. His level head, patience, and strong work ethic make him a valued team member on every project.

Outside of work, James enjoys life in the Southern Downs with his wife, Isabelle, and their two young daughters.

Lachlan Rigden

Lachlan is heading toward his third year of his Apprenticeship with GHC.

Beginning as a school-based apprentice, Lachie then traded in his books for a nail bag and hasn't looked back.

We're thrilled with how Lachie is progressing in his trade and look forward to seeing him continue his apprenticeship and become a quality chippy!

Ethan Flood

Also known as 'little Ethan' - we're working on being more creative with our nick names!

Ethan joined the team as a school-based apprentice and this year has elected to go full-time.

He's learning the ropes on site and picking up valuable skills and life lessons on the way!

This could be you!

Stephen O'Gorman

GHC has an unofficial policy of always keeping an Irishman on the team.

When we sadly had to farewell Murph as he headed home, we quickly replaced him with Steve who hails from Limerick.

His accent is thicker than Murph's so it's hard to tell if his jokes are as good but he always brings a smile and plenty of enthusiasm to the job.

In all honesty though, since he started with us in 2020, Stephen has become indispensable.

Beau Bannon

Beau is a local boy who began his apprenticeship as school-based until completing Year 12 and going full-time.

Over the course of his apprenticeship Beau has continued to grow in confidence and capacity on site and shows plenty of potential to lead his own team in the future.

Beau is on track to be come a fully qualified chippy at the end of this year and we're excited to see where life takes him next.

Ethan Stead

Ethan came on board in mid-2024 as a mature-aged apprentice, bringing with him a strong work ethic and a fresh perspective.

Having grown up on the land and working in his family’s farming business, Ethan developed a hands-on approach, a can-do attitude, and a natural sense of responsibility — all of which translate seamlessly to life on the job site.

He’s a pleasure to work with: motivated, reliable, and always willing to lend a hand. Ethan has quickly become a valued part of the GHC team, and we look forward to seeing his skills continue to grow.
