Welcome to Sigma
Research.

Jeppeson developed the idea for Sigma Research in 1987. She was then working as
a statistical consultant from her Tempe, Arizona office while finishing her
Doctoral comprehensive examinations.
Sigma Research formally opened its doors in 1990 when our Arizona Trade Name
was established, and the
office our office has been located in Chandler, Arizona since 1993.
Since that time, we have progressed and work has developed in some of the most
