Foster Group Inc. announced it will move on Sept. 8 to a larger facility in West Des Moines. The relocation stems from Foster Group’s need for additional space to accommodate growth in demand for its services, the fee-only wealth management services firm said in a release. Its new location at 6601 Westown Parkway, Suite 100, is nearly 20 percent larger than its current space at 1001 Grand Ave. Foster Group will occupy space on the first level of a multi-tenant office building; the floor plan will allow for greater efficiency in how the firm serves clients and conducts internal communication. The company’s main phone number will remain the same.
