Peak
performance
for people
and business
Derridale was founded in 2001 by Paul and Ryl Gardner.
Together, they bring more than 70 years of combined experience across leadership, business improvement, and people strategy. Their work spans mining, construction, manufacturing, services, and government.
Derridale was built on a simple idea. When people perform well, businesses perform well.
The approach is practical and direct. Focus on what matters. Deal with issues early. Keep people accountable.
The name Derridale comes from a family dairy farm. It reflects the values the business was built on: hard work, honesty, and community.
Those values still guide how Derridale works today.
“Derridale has been instrumental to our success from start-up to significant growth; true professionals of the highest calibre.”
