About Us

MRSB opened its doors more than 37 years ago as a small accounting practice led by Managing Partner Shaun MacIsaac, CPA, CA. His goal was to provide exemplary service to businesses and individuals on Prince Edward Island, helping them to achieve their short-term and future financial goals.

We've now grown to a team of over 45 advisors and five professional divisions, with offices in Charlottetown and Summerside. Our primary goal is much the same as it was when we started: to provide value beyond financial statements and basic business planning, partnering with you at every stage of your growth to achieve exceptional results.

We base our service approach on four main tenets: 


A defining aspect of our approach is that we offer the wide-reaching expertise of a large financial and professional services firm and the specialized knowledge and personalized approach of a small, local one. This means you can come to us at any stage of your development and stay for the duration of your growth.
