Working with a new energy 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 energy practice — ask which fits.

• How much does it cost to hire Dennis for a energy 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 energy attorneys offer free consults — check Dennis's current terms during booking.

• How long do energy cases in this state typically take?

  Simple energy 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 the area?

  Dennis evaluates matters case by case. If the venue is outside Dennis's regular jurisdictions, the intake call will confirm whether direct representation or a referral makes more sense.

• 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 energy clients right now?

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