GRAND RAPIDS – Open Systems Technologies, better known as OST, entered the Chicago market in January, joining other OST locations in Detroit, Ann Arbor, Minneapolis and London, England.

?We selected the Oak Brook area because it is central to many large businesses, close to the airport, major freeways, has reasonable access to downtown Chicago, and, for our employee?s benefit, it?s within 30 minutes commute of many great neighborhoods,? said OST President Meredith Bronk.

OST, with 180 employees generating $120 million in annual billables, serves clients in healthcare, manufacturing, finance and insurance.
