Mr. McMahon has thirty years of experience in representing small and mid-sized business that contract with the federal government.  This is in addition to several years of practice and service in the United States Marine Corp where he served as a platoon commander and later as a member of the Navy Judge Advocate General’s Corps.  In addition to criminal trial practice and experience in implementation of International Law, Mr. McMahon served the Secretary of the Navy and the Secretary of Defense in a legislative liaison capacity where he interfaced with the staff and members of Armed Services Committees of the U.S. House of Representative and the U.S. Senate.  In this later service, he also interfaced frequently with multiple departments of the Executive Branch.  It is this government experience that has served him well as an attorney who represents, almost exclusively, service and support contractors that contract with the federal government.

Mr. McMahon’s practice includes representing large and small businesses, predominately small to mid-sized federal services and support contractors, most of which range in size from start-up through $300 million in annual revenue.  Most of his clients are providers of information technology support services to the various agencies of the federal government, including the Department of Defense.  The legal support services most frequently sought by these clients include GAO and Court of Federal Claims bid protests; review/drafting/negotiation of teaming and subcontract agreements; resolution of prime-subcontractor disputes; and resolution of prime contractor disputes with their federal customers.  In addition, because his client base consists of many small to mid-sized companies, he is also frequently consulted on business formations, business structure, internal controls and disputes, boards of advisors and other day to day business matters.   His relationship with his clients is often much like that of an in house counsel, relied upon by management to address their various legal challenges.

Mr. McMahon also has a great deal of experience with the U.S. Small Business Administration (SBA) and its various contracting programs.  Because his client base includes many minority owned and veteran owned firms, he has developed a keen interest in the rules and regulations promulgated by the SBA which impact small business contractors.  In this connection, he has assisted clients in obtaining certification in the SBA’s Minority Business 8(a) Program, in addition to qualifying Veteran owned firms and HUB Zone firms.  He has also represented clients in connection with SBA Size Protests and other eligibility challenges.
