Our Firm
Reimagining the Client Experience
The SlateStone Advantage
Our approach is to focus on your success
The cornerstone of sound financial advice begins with a broad understanding of your objectives. Our clients are wealthy individuals and families who want to partner with an independent advisor who takes the time to truly understand their goals and aspirations.
