Tell C3 about your project

Send a few details about your project or matter. We strive to reply within two business days. The first call is a free 15-minute conversation, and if it isn't something C3 can help with, we'll say so.

Contact form

C3 uses this to check for conflicts of interest before the intro call.

A few sentences is plenty. Please don't send confidential documents until after the intro call.

What happens after you send your message

You'll know quickly whether C3 is the right fit, and you'll leave your first call with a clear next step.

  1. A reply within two business days. We strive to answer every message within two business days and suggest times for your free 15-minute intro call.
  2. A quick conflict check. C3 uses your project's city and county, and the parties' names if there are any, to confirm there is no conflict of interest before the call.
  3. A candid first conversation. You describe the situation in your own words, and Dennis tells you what the code requires and where you have options. If it isn't something C3 can help with, you'll hear that on the call.
  4. Your next step. If it's a fit, C3 outlines the scope and fee for the work, and nothing starts until you agree.

Please hold off on sending confidential documents until after the intro call.
