Sean has worked in financial services for over 25 years. The bulk of that time has been with the RI Advice Group (and RetireInvest) looking after clients on Sydney’s northern beaches and beyond.
With a background in Engineering Surveying, Sean decided on a career change in the year 2000 and took on a role at one of the original RetireInvest offices, in Mosman, Sydney.
In late 2005, Sean set up the RI Advice Brookvale practice. After over 15 years located in Brookvale, the business moved to new premises in nearby Dee Why in 2021 (where it remains to this day).
In November 2025, RI Advice Brookvale merged with another RI Advice practice, Finsura Wealth Management P/L.
For the past 20 years or more, Sean, with the assistance of a team of dedicated support staff, has built an enviable reputation for providing quality advice and service to long-standing clients.
Sean gains particular satisfaction from seeing long-term clients living out the lifestyle to which they have aspired as a result of his strategic financial advice.
Sean holds the internationally recognised Certified Financial Planner™ or CFP® qualification, is a member of the Financial Advice Association Australia (FAAA) and has a Diploma of Financial Planning. With these qualifications and experience, Sean is well qualified to help clients achieve their financial goals.

I have been a financial planning professional for over 10 years. I hold the internationally recognised Certified Financial Planner™ qualification, Bachelor of Business, Advanced diploma in Financial Services and am involved in the Self-Managed Superannuation Fund Program.
As a Senior Financial Planner I specialise in the following strategies: wealth creation, insurance management, superannuation, retirement planning and tax effective investment.
Outside of work I enjoy playing and watching sport. I am a proud supporter of St George Illawarra during the winter months, while in summer I like to spend time at the beach. Socialising with friends and spending time with family is my favourite pastime.
