The Costello Law Firm, P.A. is a South Florida-based law firm dedicated to providing strategic and aggressive legal representation in matters involving foreclosure defense, landlord-tenant disputes, and criminal defense. We represent clients throughout Fort Lauderdale and the surrounding South Florida communities, while also maintaining a presence in New York to serve clients with matters spanning multiple jurisdictions.

We understand that our clients often come to us during some of the most stressful and uncertain moments in their lives—when their home, their rights, or their freedom are at risk. Our mission is to provide clear guidance, decisive action, and results-driven representation when it matters most.

At our firm, every case is handled with a hands-on, personalized approach. Clients work directly with their attorney, not passed off through layers of staff. We take pride in being responsive, accessible, and proactive in protecting our clients’ interests, whether that means defending against foreclosure, resolving complex property disputes, or fighting criminal charges.

With experience across multiple areas of law and a strong understanding of both litigation strategy and negotiation, The Costello Law Firm is committed to achieving the best possible outcome for each client.

The firm is led by Mark Costello, Esq., a licensed attorney in both Florida and New York, allowing the firm to effectively handle matters across state lines.
