Sharon L. Larkin, a partner in Steptoe's Washington office, has nearly 20 years of experience handling complex government contract matters.  She holds a secret clearance to assist clients with classified matters.  Ms. Larkin is identified in Chambers USA 2015 and 2016 as a “Recognized Practitioner” among government contracts lawyers nationwide, and has been selected to the Washington, DC Super Lawyers list in government contracts from 2016-2017.

Ms. Larkin represents government contractors in the full spectrum of procurement matters, with particular emphasis on bid protests, claims litigation, and dispute resolution – areas where her role as a former judge hearing contract disputes informs her understanding and insight.  She also advises and assists clients with contract negotiations, small business matters, data rights, investigations and compliance, and civil disputes.  Her clients include both large and small contractors, and her particular areas of industry focus include health care and biotechnology, aerospace and defense, information technology, and construction. 

Ms. Larkin’s experience as a judge and advocate enables her to take the most practical approach in solving her clients’ legal and business problems efficiently.  She spent 12 years with the Government Accountability Office (GAO), where she served as a Judge on the GAO Contract Appeals Board and an Assistant General Counsel in the Procurement Law Division.  Her experience at the GAO includes presiding over some of the most complex bid protests and contract appeals, including disputes involving the acquisition and performance of contracts for complex weapons systems, environmental remediation, healthcare services, information technology, and the modernization and renovation of the United States Supreme Court.  During her time at GAO, she heard more than 1,600 cases, issued more than 425 public decisions, presided over more than 40 hearings and trials, and conducted more than 65 alternative dispute resolution sessions.  Ms. Larkin won numerous awards for distinguished service, including the GAO Meritorious Service Award from the Comptroller General in 2007, and several Office of General Counsel Outstanding Achievement Awards.  

Before and after GAO, Ms. Larkin was a government contracts attorney in private practice, where she counseled clients on a variety of procurement matters and litigated cases at the GAO, Court of Federal Claims, various other state and federal trial and appellate courts, and the boards of contract appeals.  She has also served as an expert witness on procurement matters. 

Ms. Larkin chaired the ABA Section of Public Contract Law in 2013 to 2014, where she led the Section through the federal government shutdown.  She is a frequent lecturer on government contracting matters and has taught numerous classes on contract formation and administration, litigation practice, and alternative dispute resolution.  Prior to going to law school, Ms. Larkin worked for several years in the field of medical technology in laboratory medicine.
