Celebrating over 30 years of professional service.

Founded in 1982 and located in Indianapolis, Indiana, Circle Design Group is a consulting engineering firm offering HVAC, civil, plumbing/fire protection, lighting and electrical design services.  

On January 1, 2018, we were  excited to announce the merger of Circle Design Group, Inc. and Enverity Engineering into one company – CIRCLE DESIGN GROUP.  Providing consulting engineering services for 35 years and 15 years respectively, the union assembles a team of hardworking professionals focused on providing budget conscious, client focused engineering solutions within established project schedules.

Together we have combined expertise with corporate office buildings, hospitality, conference centers and convention spaces, retail malls and mixed-use developments, sports and performing arts venues, educational facilities and libraries, healthcare facilities and fitness centers, manufacturing and distribution, and many more. We will continue to offer all our clients the same personalized attention for projects as large as the JW Marriott, The Palladium at the Center for Performing Arts, or Indianapolis International Airport, and for those as small as a quaint restaurant, a sacred church, or a restoration of a historic building. Our personal expectations of service to the client, listening carefully, and developing solutions that truly meet their expectations and needs remain the same.

With expertise in the mechanical, electrical, lighting, plumbing, fire protection and civil engineering disciplines, our talented employees will continue to be led by Kerry Smith as Director of Engineering. Rita Smith will manage day-to-day business operations as President.  Ross Maue will work to continue strengthening the team and our client relationships as CEO.  Our merger is positioning us for additional growth and the potential of adding new long-term clientele.
