BUILT ON SERVICE
As a CVE-verified Service-Disabled Veteran-Owned Small Business, service is part of who we are. Founded and led by Principal Architect Todd Stone, a service-disabled veteran, Stone Group Architects was built on the values of duty, integrity and respect for those who serve.
From VA facilities to military campuses across the country, we are proud to be veterans serving veterans. Our team understands the responsibility that comes with designing for our nation’s military and medical communities and approaches that work with the care and respect it deserves.
That commitment extends beyond the buildings we design. Through The SGA Honor Project, we recognize, preserve and share the stories of veterans and memorials, honoring their service and strengthening the connection between people, place and the communities we serve.

“We had a great partnership working with Stone Group on the Siouxland Expo Center project. I appreciate their willingness to work along side of us throughout the design process. Their attention to detail and quality control led to a facility that has become a tremendous asset to Siouxland.”
“I highly recommend Stone Group Architects to assist golf courses in developing and maintaining clubhouse amenities to support financial success of the course and to support club membership. Please do not hesitate to contact me with any questions regarding our experience with Stone Group.”
“Firm is quite responsive and well organized through design and production of working drawings and submittals. They do a good job of anticipating issues related to design and construction so they may be dealt with earlier than later. Good follow through with contract related items.”
