How We Are Different

  1. The impact we have on our clients’ lives

    Over the years, we have had the opportunity to see substantive changes take place in how our clients approach and manage their finances. What may have been a major source of stress begins to ease, replaced by peace of mind and a real sense of confidence in their future. Our clients tell us their lives have been changed for the better as they gain clarity and control over their financial future.

  2. Our advocacy on behalf of our clients

    Developing and maintaining strong collaborative relationships with our clients’ other professionals is a major part of what we do as their financial advisors. Whether they have existing relationships or need a referral to someone we would recommend, we provide help with organization, coordination, and sometimes even negotiation to make sure our clients get the best assistance possible.

  3. Our systematic, disciplined approach to investing

    We combine the academic methodology of asset-class investing, with its broad diversification, efficiency and low cost, with specialized, tactical investment programs that are designed to solve specific planning or tax issues.  This disciplined approach helps our clients stay focused on their long-term goals and avoid the temptation to react to emotions triggered by short-term market events.
