• How much does it cost to hire David for a environmental case?

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

  Simple environmental 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. David gives a realistic estimate for your facts at the consult — vague answers here are a red flag.

• Can David take my case if I'm outside Washington?

  David is licensed in District of Columbia. Matters governed by District of Columbia law are the natural fit. Out-of-state matters are handled case-by-case, sometimes with local co-counsel. Ask during intake — David 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 David?

  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. David will filter what matters — over-preparing at intake is always cheaper than needing a second meeting.

• Is David accepting new environmental clients right now?

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