Lawyer, Civil Practitioner

Collaborative Practice has been my focus since 2003. After I received Collaborative Practice training in 2002, I was convinced that Collaborative Practice offers a reasonable, respectful way to resolve family and other issues. I founded the Ithaca Area Collaborative Law Professionals in 2003. With my colleagues, I have made it a priority to extend Collaborative Practice in Central New York and beyond.

Collaborative Law is the focus of my practice. I have been representing clients in collaborative law since 2003 and have presented several trainings. One of my areas of interest is to expand collaborative practice to meet the needs of LGBT clients and to other practice areas (such as business law, probate and real estate law).
