About Us

Third Sigma Investment Advisors, LLC  is a Registered Investment Advisor (RIA).  We provide asset allocation advice and discretionary implementation services for our clients.  We also provide custom investment advisory services to clients with larger investment portfolios.    Our professionals have over 35 years combined investment experience. This experience infuses our work and advice with wisdom and expertise that is often missing in other investment advisory firms.   For example, we strive to offer low-cost sophisticated investment solutions that serve the client first and naturally, as a result of diversification, perform well over a full market cycle. Another major focus of our business is defined contribution plans such as 401K plans, 457 plans, and SEPs, as well as other deferred compensation such as money purchase plans.


We have recently moved to a new location!

We Put Our Client's Interest First

As an Investment Advisor, our fees are asset-based, based on total client assets, which aligns our interests with our clients and further encourages us to grow our clients’ assets over time.   We do not receive commissions or other fees from third parties for investment advice or retirement planning .We are proud to always act as your fiduciary.
