C. Marie Eckert

Clients value my pragmatic and thoughtful approach to resolving legal problems; the first step in that process is listening. Having been a client myself for several years, I am adept at assessing risk and reward, cost and benefit, recognizing when a case should be tried, and when a dispute is best resolved outside of the courtroom.
