Customized Management
All of our portfolios are managed individually; we take pride in our ability to tailor our services and investment strategies to meet client-specific objectives.
Client Servicing
We work with clients to customize strategy, guidelines, benchmarks and risk tolerances and are often asked to participate in investment-related discussions outside of our portfolio management assignment. Additionally, we seek to manage our growth to maintain excess capacity so that we can continue to provide a high level of customized service. 
Disciplined Style
We take a highly analytical and quantitative approach that emphasizes research of the overall economy, different market sectors and industries, individual security structures, and credit.
