Where we
work.
We operate from Arlington Heights across 93 communities in seven Illinois counties — Cook, DuPage, Kane, Lake, Will, Kendall and McHenry — and take engagements nationally and internationally. Each community below has its own page, because a five-acre estate district, a bungalow block with alleys behind it and a county courthouse are three entirely different jobs.
