Founded in 2020 by Peter Sullivan, a veteran attorney with over 25 years of experience at some of the nation's most elite law firms, the practice is dedicated to helping individuals navigate the complexities of divorce and family restructuring.

If you are looking to hire a divorce attorney who prioritizes your goals and well-being, this firm offers a client-centric approach that sets them apart.

  • Uncontested Divorce: Efficient and cost-effective solutions for amicable splits.
  • Prenuptial Agreements: Drafting clear contracts to protect assets before marriage.
  • Child Custody: creating parenting schedules that serve the best interests of the children.

Elite Experience, Personalized Service

Peter Sullivan's background includes working with top-tier firms in New York and Chicago, handling high-stakes criminal defense and complex civil litigation before focusing exclusively on family law. This broad legal foundation allows him to spot issues that others might miss, particularly in divorces involving complex assets or business interests.
