Leadership Team

At MSI Engineers we’ve embraced the collaborative model of leadership to capitalize on the principal’s and staff’s different but complementary backgrounds and skill sets.  From our receptionist to our principals, each member of our staff is encouraged to share their ideas and be open minded.  As principals we provide clients with the leadership, expertise, and support needed for successful projects, while also striving to empower our employees with guidance, direction and opportunity.
