About Us


SEI Design Group specializes in design,
planning and consulting; established on the principle of
providing superior quality and exceptional client support.


Six individuals came together to create
fertile ground where architecture and ideas thrive.

In 2006, SEI Design Group was formed by the six founding Principals, Victor J. Tomaselli, AIA, Stephen J. Klempa, CCM (retired), Brian E. Cieslinski, Bari J. Lee (retired), Michael J. Ebertz, AIA, and Matthew S. Monaghan, AIA, who all left a successful firm to start a new company. How it all came about, how we picked our name, etc... is an interesting long story. Please go to our inception story in our blog for find out more about SEI.



Building bridges into the future

A few of our founding principals are now happily in retirement after building a successful company. The remaining founding Principals continue to move forward with new Principal partners along with an extensive team of professionals that energizes our company and keeps our momentum going.

Our individual, unique work experiences compliment one another in our ability to meet the diverse and challenging needs of public and private clients alike. We pride ourselves on being seasoned professionals who understand the intricacies of complex problem solving within our industry and profession.

Superior Quality - Excellent Client Support

We do what is needed to maintain our level of excellence in any project we are part of.

We are very fortunate to have great clients. The way we keep these clients is with our passion for supporting them in any way we can. Our profession as architects requires a lot of oversight and constant visits to our project locations. We know our clients need us there. To address this, we opened three offices to better cover NY state and beyond.

Our downtown Rochester office, located in High Falls Area is located inside an old mill building we chose to remodel. This resulted in a prestigious design award for the SEI Team.

In Albany, our office is located on Wolf Road which also has easy access to all our projects on the eastern side of the state. Our office in Binghamton facilitates the management of our projects in the Central region of New York.

Awards & Recognition

Recognition is always welcomed, especially when it is for the thing we love the most...
