Mr. Brennan, after graduation from law school in 1987, worked for two large D.C. law firms, a small bankruptcy boutique law firm and as assistant general counsel for a Maryland corporation. In 1995, Mr. Brennan and Carol Waite formed Brennan & Waite PLC as a community oriented law firm to service clients primarily in the Northern Virginia area. At that law firm, Mr. Brennan provided a wide variety of legal services to small and medium sized entities, including the purchase or sale of businesses, business operations, leases, receivable collection, bankruptcy, business formation and other matters that arise during the conduct of business operations. Mr. Brennan was also first chair litigation counsel for both bench and jury trials before state and federal courts in Virginia, Maryland and D.C., as well as counsel in various arbitration and mediation proceedings. In short, Mr. Brennan’s experience in business related legal matters is comprehensive.

Mr. Brennan has also been very active in community affairs since the formation of Brennan & Waite. He was the Chairman of the Board Directors for the Reston Chamber of Commerce, Leadership Fairfax, and the Vienna Chamber of Commerce.
