Firm Profile


Since 2005 when McMahon Law Group and the Law Offices of David M. Serepca merged to form McMahon Serepca LLP (MSLLP), our firm has represented a diverse set of clients ranging from sophisticated individuals to multi-billion dollar public companies in their most challenging litigation and corporate matters.  We have an exceptional record of success because our practice areas are led by experienced attorneys who spent the first decade of their careers learning their respective specialties at among the most prestigious law firms in the world. 

We are committed to providing exceptional legal service. Where we separate ourselves from the large law firms from which we came is that because we are a boutique sized firm we are able to provide much more personal attention to the needs of our clients at half the cost.  We believe that attorneys should be accessible, responsive, and we are dedicated to distinguishing our legal representation from all other firms.
