Our Story - ISC Contracting

ISC is a St. Louis-based general contracting firm specializing in commercial construction.

The firm was founded in 1982 by the father-son team of George and Dan Green. Long-time employee Scott Seymour, who joined the company in 1988 as project superintendent, joined the ownership team in 1993 upon George Green’s retirement.

ISC has today grown to be one of the Midwest’s leading tenant finish contractors, with additional specialties in retail, hospitality and cultural/community construction. While many of the firm’s projects are in the St. Louis area, the company also completes retail assignments around the country.

Known for excellent customer service and a “we’ll-take-care-of-it” attitude, ISC has developed the trust of hundreds of owners, property managers, designers and subcontractors. Personal referrals and word-of-mouth advertising account for the bulk of the company’s business, as its name has been passed among law firms, corporations, retailers, restaurants and cultural organizations, each looking for a way to build out or renovate their space with minimum hassle and maximum value.

Our team has been involved with many tenant interior projects throughout the years. I personally want to say that this has been one of the easiest projects I have been involved with. ISC was always in control of their subcontractors and careful to follow the needs of the property, quickly addressing any concerns or problems and followed all the contractors rules and regulations to a "T".

"I like working with ISC because I always know that at the end of the project, the client is going to be happy. The people at ISC communicate well and pay attention to complex details. Their principals and project managers are extremely hands on. People like to do business with nice people, and they’re very nice people."

Our recent project in Santa Monica has been one for the ages with truly unbelievable obstacles, some seemingly insurmountable. Your team assembled on this project has been insanely focused, determined, and frankly, bulletproof. Thank you again for your partnership and know that my trust in ISC and the Project Management team helps me sleep a little bit longer each night.

"There’s no company like ISC in the construction industry. They are far and away the best general contractor we’ve ever dealt with. They are totally first class, professional, and completely responsible for making sure our needs are met."

Dan Harbaugh / President, Ronald McDonald House St. Louis
