After decades of practice at both a global law firm and my own boutique firm, I appreciate that no matter the size of the issue, my clients care deeply about their companies and their cases. From billion-dollar restructurings to six-figure lawsuits, my clients know I am 100% invested in their success and will pursue their best interests with indefatigable determination.

Mark Castillo has developed a diverse practice with significant experience in all areas of bankruptcy law, litigation, and corporate matters. Through representation of numerous Chapter 11 debtors, secured and unsecured creditors, official committees, and Chapter 7 and Chapter 11 trustees, Mr. Castillo has developed a broad knowledge of the law and the Bankruptcy Code, including pre-bankruptcy planning and prepackaged acquisitions, pre-negotiated reorganizations, bankruptcy liquidation and non-bankruptcy dissolution, assumption, assignment, and rejection of leases and contracts, utility and reclamation issues, claims objections, avoidance and recovery actions, disclosure-statement and plan drafting and negotiation, and various confirmation and post-confirmation issues. Mr. Castillo has tried suits involving millions of dollars in bankruptcy-related claims, including claims of fraud, breach of fiduciary duty, turnover, conversion, and contract claims, and has litigated or settled millions more in preference and fraudulent-transfer claims for both plaintiffs. Mr. Castillo represents numerous clients in all areas of corporate formation and management, collection of difficult receivables, and handling of various operational matters.
