Providing complete design services from ‘start to finish’, ISG has evolved into the most comprehensive, professional design firm in southern Minnesota.

ISG has been providing progressive design services since 1973. The success of the firm can be attributed to positive client relations, talented and dedicated professional staff, as well as our ability to provide creative solutions and exceptional project management services from ‘start to finish.’

Today’s projects are more complex than ever before, and often need to be reviewed in a context greater than the specific site. Budgets require that these projects are efficient and offer outstanding value, and may require funding that transcends traditional financing options. By uniting all major design disciplines in house, ISG is able to ensure that all components of the design are both carefully crafted and provide unsurpassed value for our clients.

Environmental awareness has grown from ideas to science. Whether it is identifying current resources, implementing proper practices to minimize impacts, or designing built improvements with sustainability as a key tenet, ISG fully implements these through Environmental Services staff and LEED-accredited professionals throughout our organization.

– Civil Engineering
– Land Surveying
– Landscape Architecture
– Environmental Services
– Community Resource Planning
