Service area

Where we work, and how long it takes us to get there.

We are based in Arlington Heights and attend all of Chicagoland and Illinois, with nationwide coverage beyond it. Each town below has its own page, because the counter-surveillance problem in an industrial park is not the problem in an estate district or a county courthouse.

Beyond Illinois

Nationwide, and selectively abroad.

The towns above are where we work most often, and where we can usually attend at short notice. We are not limited to them. We travel to all fifty states, and attend select clients internationally, with travel quoted separately and agreed before we go.

If your matter is outside Illinois, call and describe it. We will tell you honestly whether it is worth flying a team to you, or whether a firm closer to you is the better answer for what you actually need.
