About Margy

I love our practice because I care so deeply about my clients and their families. I handle all types of family law matters, and my approach to each case varies greatly, depending on my client’s needs and preferences. The range goes from playing a supportive role for those clients who wish to negotiate their own agreements to serving as a zealous advocate in the courtroom for those who need to submit their disputes to a judge for resolution.  In addition to practicing law, I speak and write about family law issues.  My first book, KEEPING IT CIVIL: The Case of the Pre-Nup and the Porsche & Other True Accounts from the Files of a Family Lawyer, was published by Algonquin Books in 2013, and I blog regularly for Huffington Post, Daily Worth, and my own blog: www.familylawunraveled.com
