JOHN CAPPIELLO, ESQ. is a trained and certified mediator and family law attorney based in New York City. After a decade of experience in the field John launched CAPPIELLO LAW & MEDIATION in 2025 to provide individuals & families with highly personalized, cost-effective and accessible mediation and family law services. 
As career litigator John has handled hundreds of family law matters in court. The takeaway? There are rarely “winners” in litigating family disputes. Regardless of the outcome the litigation process leaves individuals and families burnt out, scarred and financially depleted. In court you’ll receive long adjournments and inadequate personalization from the bench. 
In private mediation sessions John provides you with the time, attention and space you deserve to make real progress toward resolving even the most complex family disputes in the most fair and equitable way possible. 
John serves folks from all walks of life, in New York and across the country. A proud member of the gay community John specializes in working with LGBT+ clients with the awareness and personal understanding that gay and queer relationships are unique, and therefore, often require creative legal solutions when in turmoil or separation. 
John is a graduate of the Loyola University Maryland and Northeastern University School of Law. He is admitted to practice law in the State of New York and is a proud member of the LGBT Bar NY, where he previously served as co-chair of the Family and Matrimonial Law Committee (2020-2023). John is also a member of the Family and Divorce Mediation Council of Greater New York. 
In addition to his work at CAPPIELLO LAW & MEDIATION, John serves as Of Counsel to Rosin Steinhagen Mendel, PLLC, a boutique family law firm in Manhattan. 
A volunteer at heart, John is a Teach For America alumni and currently serves on the Advisory Council for FamilyKind, a non-profit organization supporting families through the tumult of divorce. 
A Connecticut native John lives in New York City with his husband, William, and their chihuahua, Ripley.
