The Best Lawyer for Child support/mediation and settlements. My first divorce settlement and parenting time was not good, and I went through a difficult time. But my friend has referred Christine Callahan to me, and this time my mediation, revised settlement and parenting time went well on time and no issues. Christine is a very client focused lawyer, and she will get it done what you are expecting, good negotiator and a good person/advisor. Response to your questions/concerns or any clarifications on time. Awesome lawyer and a good person!!
