Marcus is the Co-Founder of Donor Republic, a full service fundraising marketing agency assisting many of Australia's favourite charities with their fundraising strategy and campaigns. Immediately prior to that, he worked as the General Manager of Marketing and Fundraising with Cerebral Palsy Alliance for eight years. His role encompassed fundraising, brand development and client service marketing. Over that time fundraising grew from $12m to $31m. Marcus has worked in similar roles for Cancer Council NSW and QLD for six years, and, prior to that, a small HIV/AIDS charity.

He founded the current incarnation of the innovative social change campaign, 'Include a Charity', funded by 140 Australian charities to increase the number of people who leave a gift in their will. Twenty-four years of transforming charities have given Marcus a wealth of experience covering strategic planning through to execution across almost every area of charitable giving. Setting up an agency to share that expertise and assist other causes seemed a natural step in his career, and in the ten years since it was founded, the agency has partnered with over 300 charitable causes.

It's easy to see why Donor Republic has become Australia and New Zealand's most sought after agency, carving its reputation on constantly delivering results from a team of specialist fundraisers and creatives. It's what earned them the FIA's Supplier of the Year award many times, and saw Marcus named FIA's Fundraiser of the Year in 2024.
