About me

I am a mediator and attorney who believes civil dialogue can help prevent costly litigation (emphasis on CIVIL). I will work to keep costs reasonable and communication strong to support resolution that helps clients and their family move forward. I take the time to educate clients about the bigger picture and their choices so they can make informed decisions. I recognize most people are walking in carrying emotional distress and that they can benefit from patient, informed discussions as well as "homework" so they can have time and calm to consider their individual situations. I believe lawyers play a key role in the success and level of animosity in a case. I believe the facts should drive results rather than emotions. Please come in with your questions and concerns and let's talk about your options.
