The principals of GSG Group, Inc. joined forces in 1998 to assist clients in realizing their building project goals. They collaborated initially as Gram/Sage CM, then Gram Sage Graves, Inc. in 2003 and re-branded as GSG Group, Inc. in 2011 to acknowledge the increased diversity of services and associates that have been developed over the years.

GSG Group’s decades of combined experience in the industry enables them to pull together strong and effective professional teams. Their main office is just outside of Seattle in Edmonds, Washington, where they provide their management expertise to clients in the greater Puget Sound region, the western United States and wherever their clients’ needs may take them.

GSG Group is a team of construction managers, providing owner's representation with an emphasis on cost management.

We recognize the human dynamic in using our technical experience to maximize value to our clients.
