Choosing a mediator in a family law case is a very personal decision. Devon is a professionally trained mediator with nearly two decades of experience as a family law lawyer. I have seen first-hand her ability to effectively and efficiently help parties settle cases that involve complicated parenting, financial, and emotional issues. Her professional and compassionate approach are reasons why I choose and highly recommend her as a mediator.

We appreciate the work and effort Devon put into getting this matter settled – based on the long history, animosity, and lack of confidence between the parties – my client said that what Devon accomplished approached a miracle.

– Evanston, Wyoming attorney

My client’s case was individualized to Devon and my client felt heard and understood. Mediation solved all the outstanding problems and kept us from a court battle where satisfaction would not be likely found. We are glad we chose the mediation route instead of trial. Devon made a difference in my client’s life and she was so pleased with how beneficial and smooth the process was.
