True and responsive expertise – these qualities are the foundation on which ISG was built on in 1973 with a mission to provide civil engineering expertise to southern Minnesota. With different iterations of the firm name that naturally occurred overtime, today, more than 46 years later, ISG stands as an employee owned, multi-disciplinary firm serving clients in 10 office locations across the U.S.

ISG’s business philosophy is centered around building relationships, translating experience across synergistic markets to the advantage of partners, and constantly striving to add value to services by seeking new and creative technologies, professionals, and ideas. Bundled with an additional empowerment layer of having 100% of employees as owners, ISG’s success can truly be attributed to a strategic, intentional, and entrepreneurial mentality that is focused on being different; not looking at just the present, but rather the future. One that isn’t bound by stale metrics or limiting job descriptions but seeks to engage and build relationships that drive success. ISG’s flexibility and accountability make it possible; the firm’s focus and innovative solutions make it happen.

On January 12, 2017, ISG formally announced its transition of firm ownership to a 100% employee stock ownership plan (ESOP). As a Top 500 Design Firm designated by Engineering News-Record (ENR), Zweig Group Hot Firm, and PSMJ Circle of Excellence recipient, ISG has consistently focused on increasing talent, expertise, and overall sustainability. #ISGIngenuityatWork
