OUR TEAM
You can’t achieve sustainable growth without the support of a great team. While building Platinum Group into the premier provider of back-office HR Payroll and Accounting services, Michael Murphy realized he needed a group of like-minded professionals. He searched for people who excelled in their jobs and yet remained passionate about their own priorities. No matter what division of Platinum Group you’re working with, our team thrives on a foundation of camaraderie, support, service and collaboration that is used with each other and our working clients.
