About me

I have been a practicing attorney for over 20 years.  Most of my legal career has been focused on family law; however, I started my litigation experience in San Diego as a prosecutor.  I also worked as an attorney for the United Nations Mission in Kosovo and taught International Law at the University of Denver.  I converted my love of family law and international law into a practice of International Family Law.  About 30% of our practice at Frost & Beck, PC, involves an international component; 60% of our practice is domestic family law inclucing child custody and divorce, and 10% of our practice is family law appeals.  I have won appeals in the 10th Federal Circuit; Colorado Court of Appeals and California Court of Appeals. As of January 18, 2016, I have never lost an appeal.
