In 2006, six dedicated design professionals got together with one goal in mind: deliver quality architectural projects to their clients with a specific focus on design, value, Owner satisfaction and creativity. One of the cornerstones of the firm was to assign two Owner level Principals to each client and develop a relationship of a “trusted advisor” with the ultimate goal of retaining a “client for life” synergy between owner and architect.

It is with this philosophy that the six original Principals – Bari Lee, Brian Cieslinski, Matt Monaghan, Michael Ebertz, Steve Klempa and Vic Tomaselli started SEI (sei, the word for “6” in Italian) by leaving a large design firm to start a venture on their own. Starting with one client, SEI has grown slowly and steadily over the last ten years. At first the projects were small and staff were slowly added in late 2006 and 2007. By 2018, the firm has grown from one client to over 65, and staff growth has developed from six to 51.
