     We have acted as counsel to Aurora Diagnostics Holdings, LLC, a Delaware limited liability company, and Aurora Diagnostics Financing, Inc., a Delaware corporation (together, the “Issuers”), and the guarantors listed on Annex A (the “Guarantors,” and together with the Issuers, the “Registrants”) in connection with the filing of the above-referenced Registration Statement (the “Registration Statement”) with the Securities and Exchange Commission (the “Commission”) to register under the Securities Act of 1933, as amended (the “Securities Act”), (a) $200,000,000 aggregate principal amount of the Issuers’ 10.750% Senior Notes due 2018 (the “New Notes”) and (b) the related guarantees of the New Notes by the Guarantors (together with the New Notes, the “Securities”) to be issued under an Indenture, dated as of December 20, 2010, as supplemented by the First Supplemental Indenture, dated December 31, 2010, the Second Supplemental Indenture, dated December 31, 2010, the Third Supplemental Indenture, dated June 2, 2011, and the Fourth Supplemental Indenture, dated August 1, 2011 (together, the “Indenture”), among the Issuers, the Guarantors and U.S. Bank National Association, as Trustee (the “Trustee”). Following the effectiveness of the Registration Statement, the Registrants intend to issue the Securities to the holders of $200,000,000 aggregate principal amount of the Issuers’ 10.750% Senior Notes due 2018 (the “Old Notes”) in exchange for such Old Notes and the related guarantees of the Old Notes by the Guarantors (together with the Old Notes, the “Old Securities”).

     This opinion letter is rendered pursuant to Item 21 of Form S-4 and Item 601 of the Commission’s Regulation S-K.

     Our opinion set forth below is limited to the laws of the States of Alabama, Delaware, Florida, Georgia, Michigan, Minnesota, Nevada, North Carolina, New Hampshire, New Jersey, New York, South Carolina and Texas and the Commonwealth of Massachusetts and the federal laws of the United States of America to the extent referred to specifically herein, and we do not express any opinion herein concerning any other laws.
