ToniAnn Grande


ToniAnn’s practice encompasses all aspects of family law, including divorce, divorce mediation, collaborative divorce, equitable distribution of business and financial assets, negotiation and drafting of prenuptial and postnuptial agreements, and child custody and support matters. ToniAnn's clients have included successful businessmen and women, professionals, executives, entertainers, and their spouses and significant others. She is frequently sought out by other attorneys as their counsel in connection with family law matters. 

Although ToniAnn is an experienced litigator, she has concluded that a settlement-based approach is the best path to resolution for most families. Whether she is acting as an attorney or a mediator, ToniAnn strives to achieve practical, cost-effective solutions to the unique challenges facing each of her clients.

After graduating from New York University School of Law, ToniAnn began her legal career as a law clerk to the Honorable Max Rosenn of the United States Court of Appeals for the Third Circuit. She practiced commercial litigation at Sullivan & Cromwell LLP before leaving in 2004 to pursue her dream of representing individuals in their personal legal matters. After practicing for six years with a well-known New York City matrimonial boutique, ToniAnn started her own practice in 2010.
