Southern National Bancorp of Virginia, Inc. (the “Company”) is filing this Current Report on Form 8-K/A as Amendment No. 1 to its Current Report on Form 8-K filed with the Securities and Exchange Commission on March 7, 2007 to report that (1) BDO Seidman, LLP (“BDO”) has completed its audit services for the year ended December 31, 2006, (2) the Company filed its Form 10-K for the year ended December 31, 2006 on March 21, 2007, and (3) as a result of the foregoing, the Company’s dismissal of BDO as its independent registered public accounting firm became effective on March 21, 2007 when the Company filed its 10-K for the year ended December 31, 2006.

BDO’s reports on the Company’s financial statements for the period from inception at April 14, 2005 through December 31, 2005 and the fiscal year ended December 31, 2006 did not contain an adverse opinion or a disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principle.

During the period from inception at April 14, 2005 through December 31, 2005, the fiscal year ended December 31, 2006 and the subsequent interim period through March 21, 2007, there were no disagreements with BDO on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of BDO would have caused such firm to make reference thereto in connection with its reports on the Company’s financial statements for such periods.

During the period from inception at April 14, 2005 through December 31, 2005, the fiscal year ended December 31, 2006 and the subsequent interim period through March 21, 2007, there were no reportable events as defined in Item 304(a)(1)(v) of SEC Regulation S-K.

The Company has provided BDO with a copy of the above disclosures and requested that BDO furnish the Company with a letter addressed to the SEC stating whether it agrees with the foregoing statements by the Company and, if not, stating the respects in which it does not agree. A copy of the letter from BDO is filed herewith as Exhibit 16.1.
