Founded in 1992, Sigma Investment Management is a fiercely independent, fee-based registered investment advisor.

We provide institutional-style management for individuals, families, trusts, charitable endowments, corporations and retirement plans.

Our approach is strategic, tactical and objective. We listen to you, understand your situation, and then build a customized portfolio strategy designed to manage risk while addressing your short-term needs and long-term goals.

Although we may not always tell you what you want to hear, we always tell you what you need to hear.

Your peace of mind is our measure of success. To reach that, we bring knowledge, discipline and empathy to the investment process and work hard to earn your trust.


We put our expertise to work for you.

You’re expert at what you do, and you’re looking for an experienced guide to bring unsurpassed knowledge and pragmatism to bear in helping you meet your financial goals. We apply our deep understanding of investing and the markets, and collaborate with you to form a carefully crafted, overall investment plan.


We live by process over fads

You’ve heard—and lived through—the financial horror stories of the past several years. We’re the partners who stand their ground to follow an investment strategy designed for your peace of mind. And like you, we’re in it for the long haul, taking care of the details while looking to the future.

We help you cut through the noise and chatter, and we won’t succumb to get-rich-quick ideas or knee-jerk reactions to trends of the day.


We care as much as you do.

While deep knowledge of the financial world and a disciplined, diversified approach to investing are vital, they are not enough.

Rest assured we have your best interests at heart. We do what’s right for you, not what’s popular or comfortable. We make decisions with you in the context of your whole financial life.
