Source: Barron's.com (May 2024) 2024 Barron's Top 250 Private Wealth Management Teams awarded in 2024. The teams are ranked on a variety of factors, including their size and shape, their regulatory records and credentials of their members, and the resources they have at their disposal to serve their client bases. The rankings are meant as a starting point for clients looking for an advisor—a first-pass vetting that can help investors narrow a search. Every advisor will have his or her own approach to investing, financial planning, and other services. Clients are encouraged to approach a search for an advisor the way they would a search for a doctor—interviewing multiple professionals and getting opinions from multiple third parties. Rankings are based on the opinions of Barron's and this ranking may not be representative of any one client’s experience. This ranking is not indicative of the Financial Advisor’s future performance.

Approach

Discovery Process
Investing the time to learn about you and your family; your assets and liabilities and the risk exposures, enables us to formulate strategies and customize the relationship to your needs.
Formulation of Tax, Trust and Estate Strategy
Working with your tax and legal advisors, we help analyze your income and estate tax circumstances to identify and tailor planning techniques that may be used to address your objectives.
Creation of Customized Strategic Asset Allocation
Your customized asset allocation reflects risk, opportunities and taxation across multiple entities, while integrating your investing and estate plans.
Integration of Tactical Asset Allocation
Short-term adjustments seek to capitalize on temporary market distortions. Before making adjustments, we analyze the impact of taxes and trading costs on potential returns.
Implementation of a Customized Wealth Strategy
After comprehensive due diligence and analysis of expected results across multiple market scenarios, strategies are chosen from our expansive investment platform.
Ongoing Assessment
In coordination with your other advisors, we can conduct ongoing reviews and comprehensive reporting to ensure that your strategy adapts to changing financial and family needs.
