Contact Me:


Lewis S. Calderon is a litigator, mediator and collaborative professional with over 25 years of experience with complex litigation and appeals. For the last nearly 20 years, Mr. Calderon has helped families going through conflict in his role as mediator and as attorney for parents, children, grandparents and foster parents in divorce proceedings, Family Court proceedings and the Appellate Divisions concerning issues of divorce, child custody and visitation, relocation, child neglect and abuse, domestic violence and orders of protection, grandparent visitation, termination of parental rights, paternity and child support. Prior to that, Mr. Calderon practiced for 8 years in complex commercial matters in the construction and surety industry and in professional liability defense, representing contractors, surety companies, attorneys and accountants in State and Federal Court. With his vast experience in high conflict Family matters as attorney, mediator and appellate counsel, Mr. Calderon offers a unique combination of compassion and legal acumen that provides his clients with the best chance for a favorable outcome.

Experience has taught that divorce does not necessarily cause harm to children, rather it is conflict between parents that causes harm to children.  As a product of divorce, a foster parent and having witnessed firsthand the impact that litigation has on families and especially upon children, Lewis Calderon has concluded that mediation or the collaborative resolution of family disputes is much preferable to litigation. Aside from saving the families significant amounts of money and time, mediation and collaboration act to reduce conflict and improve communication so that even where the parents will no longer be together, the family will still function, and the children can thrive. Lewis S. Calderon is available to mediate any family dispute from divorce and separation to issues with children or the elderly.

As an appellate attorney, Lewis S. Calderon has argued well over two hundred appeals in the Appellate Division and Second Circuit. Appellate practice differs from trial practice in several fundamental ways. The success or failure of an appeal can be significantly influenced by the appellate brief.  Mr. Calderon’s extensive experience on appeals and superior research and writing skills is borne out in the quality of his appellate briefs.  Mr. Calderon has a proven track record of victories including reversals in child neglect matters, relocation, orders of protection, child custody and visitation, child support, delinquency, ERISA and surety bond law.
