Throughout my professional career, the lessons my parents taught me at a young age have driven my curiosity, my desire to help others, and to share my love of personal finance. - Gillian McCarthy, CFP®

As a second-generation financial planner, I started setting goals for myself personally and financially at a young age. The only daughter of a financial planner (father) and an accountant (mother), my childhood lessons included saving, budgeting, and planning for the future.

Today my clients benefit from the lessons that have been ingrained in me since childhood and the expertise that is a result of years of development. At Great Oak Wealth Management, we boil down the complex decisions we all face into manageable and most importantly, understandable steps.

I guide people who share a commonality of being talented in their careers but are constrained by the precious resource of time. With growing families, young executives, and those dedicated to time-intensive hobbies like my fellow equestrians; together we wade through muddy, sophisticated financial decisions to get from point A to point B without jargon or a sales pitch, but a straightforward plan and a team to rely on.

Outside of the office, my husband Dan and I spend our time on any number of projects on our small farm in Royersford. We share our farm with our dressage horses and a lovely field of cut flowers.
