Welcome to Youngman Law

Professional Corporation (YLPC). 

We have recently changed the firm name to YOUNGMAN LAW from Gasee, Cohen & Youngman, which was founded over 20 years ago and its predecessor firm over 40 years ago.  The firm’s focus was originally in litigation and collection, debtor/creditor work, with some specialties in corporate and commercial transactional law.


Mark Youngman, who initially specialized in collections, commercial and insolvency litigation, now focuses on managing the debtor/creditor practice and is hands on with real estate transactions and Wills and Estates work. 

Mark leads a team of 6 lawyers, and 18 staff in total, to ensure this small boutique firm makes a big impact with responsive customer service, simplified and stalwart legal advice. 

Our YLPC lawyers give you greater service with the help of our dedicated support team of law clerks, legal assistants, students and, always friendly, receptionist.
