Ryan Marschke


I'm really passionate about my job and always make sure my clients receive true value for money. I push for excellence all the time; I don't want to set a mediocre benchmark. I'm extremely proud of GRC's success but even more proud of the good work we do for our clients.

Ryan has extensive experience in the resources and infrastructure sector and has led a number of complex, high-profile projects in Australia and New Zealand. His experience ranges from heavy industrial mining projects, infrastructure to support commercial developments, and significant exposure to various large scale road and rail projects. Ryan manages GRC’s Resources and Infrastructure team and provides a very personal and hands on approach to his project work.
