Denis Korsunskiy

Denis Korsunskiy, founder and principal attorney at Korsunskiy Legal Group (KLG), is a distinguished legal professional and entrepreneur with over 15 years of experience in law and finance.

Before establishing his own practice, Denis worked as a tax attorney at Deloitte & Touche and BNP Paribas, advising on high-profile global transactions such as the Hilton Hotels acquisition by Blackstone, the NYSE–Euronext merger, and the Chrysler–Mercedes Benz spinoff. This deep expertise in complex financial and corporate structures honed his ability to navigate high-stakes legal and business challenges with precision and foresight.

In 2019, Denis founded his own legal practice, which began as a small medical collections firm and grew into one of New York’s leading practices in medical billing, collections, and personal injury law. His success reflects both his legal acumen and entrepreneurial drive to deliver measurable results for clients.

Today, Denis leads KLG with the same vision and integrity that have defined his career — blending rigorous legal expertise with a results-driven mindset. His mission is to provide exceptional representation, protect clients’ rights, and craft innovative legal strategies that evolve with an ever-changing landscape.
