[LOGO OMITTED] CORNERSTONE FINANCIAL CORPORATION September 16, 2010 VIA EDGAR - --------- Brittany Ebbertt, Staff Accountant Securities and Exchange Commission 100 F Street, NE Washington, D.C. 20549 Re: Cornerstone Financial Corporation Form 10-K for the year ended December 31, 2009 Form 10-Q for the fiscal period ended June 30, 2010 File No. 000-53576 Dear Ms. Ebbertt: This will confirm our telephone discussion in which I requested an extension of time to respond to the comments contained in the September 7, 2010 letter from Kevin W. Vaughn, Accounting Branch Chief. Due to previously scheduled absences by members of our senior financial reporting and loan staff, the Company will have significant difficulty responding to the comments contained in the September 7, 2010 letter within the time frame set forth therein. On that basis, I request an extension of time until October 5, 2010 to respond to the comments. Please do not hesitate to call me if you have any questions or need further information with regard to this request. Very truly yours, /S/ KEITH WINCHESTER ------------------------- Keith Winchester Chief Financial Officer 6000 MIDLANTIC DRIVE o SUITE 120 S o MOUNT LAUREL, NJ 08054 o 856-439-0300
