Working with a new consumer attorney should feel structured. Here's how the first two conversations with Mark usually go, from the moment you request a consult to the day representation begins.

Mark discusses fees during intake so the arrangement fits the matter. Contingency, hourly, and flat-fee options are all common in consumer practice — ask which fits.

• How much does it cost to hire Mark for a consumer case?

  Cost depends on the type of matter, the fee model (contingency, flat, hourly), and how contested the case becomes. Mark walks through the likely range during the consult so there are no surprises.

• Does Mark offer a free consultation?

  Mark charges for the initial consult; that fee is credited toward representation if you retain Mark's office. Some consumer attorneys offer free consults — check Mark's current terms during booking.

• How long do consumer cases in South Dakota typically take?

  Simple consumer matters can wrap in a few weeks; disputed cases can run 6–18 months from intake to resolution, longer if the matter goes to trial. Mark gives a realistic estimate for your facts at the consult — vague answers here are a red flag.

• Can Mark take my case if I'm outside Sioux Falls?

  Mark is licensed in South Dakota. Matters governed by South Dakota law are the natural fit. Out-of-state matters are handled case-by-case, sometimes with local co-counsel. Ask during intake — Mark will tell you if the case is a fit or refer you to someone closer to your court.

• What should I bring to my first meeting with Mark?

  Bring every document that touches the dispute: contracts, correspondence, police or medical reports, filed pleadings, invoices, photographs, insurance letters. Also bring a written timeline of what happened, in your own words. Mark will filter what matters — over-preparing at intake is always cheaper than needing a second meeting.

• Is Mark accepting new consumer clients right now?

  Mark's intake status shifts week to week. Submit the form; the office will confirm availability or refer the matter out.
