What Trenk Isabel Siddiqi & Shahdanian Professional Corporation does

Trenk Isabel Siddiqi & Shahdanian P.C. is a private professional corporation law firm headquartered in Livingston, New Jersey, with additional offices in Hackensack, New Jersey (opened January 2025) and New York, New York. The firm was formed in March 2022 when four attorneys — Richard D. Trenk, David L. Isabel, Asaad K. Siddiqi, and John L. Shahdanian II — joined together to build a multi-practice firm. It operates across eight distinct practice areas: Bankruptcy and Corporate Restructuring, Commercial Litigation, Environmental Law, Estate & Probate Litigation, Government Representation, Health Law and Pharmacy Law, Labor and Employment Law, and Land Use and Redevelopment. The firm's team comprises 20+ attorneys, including five Directors, multiple Partners, and Associates.

The firm serves a diversified client base that includes New Jersey municipal and county government entities, healthcare providers (notably more than 100 pharmacies in Medicaid and regulatory matters), real estate developers, enterprises such as Lumen Technologies, and individuals requiring estate and probate litigation. Differentiated expertise includes a registered pharmacist (Satish V. Poondi, elevated to Director in January 2026) chairing the Health Law and Pharmacy Law practice, and bankruptcy work spanning Chapter 11 cases involving more than $500 million in value.

The firm operates as a professional services business generating revenue through hourly billing, fixed fees, and contingency arrangements on legal matters. Go-to-market is sales-led, relying on attorney networking, bar association leadership, client referrals, thought leadership (publications and speaking engagements), and recognition in legal directories such as Chambers USA, Super Lawyers, Best Lawyers, Lawdragon 500, and Martindale-Hubbell. There is no proprietary technology platform; service delivery occurs through direct attorney-client relationships across the firm's three physical office locations and nationally where specialized matters require it.
