Dennis's primary office is at 666 Fifth Avenue, New York, NY, 10103. In-person meetings are by appointment; a phone intake usually comes first.

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

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

• How much does it cost to hire Dennis for a business case?

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

• Does Dennis offer a free consultation?

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

• How long do business cases in New York typically take?

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

• Can Dennis take my case if I'm outside New York?

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

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

• Is Dennis accepting new business clients right now?

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