Re: Registration Statement on Form S-4

Ladies and Gentlemen:

We have served as Maryland counsel to Sheridan Anesthesia Services of Maryland, P.C., a Maryland corporation (the “Company”), in connection with certain matters of Maryland law arising out of the registration by AmSurg Corp., a Tennessee corporation (the “Issuer”), of (a) up to $1,100,000,000 aggregate principal amount of the Issuer’s 5.625% Senior Notes due 2022 (the “Exchange Notes”) and (b) the guarantee by certain subsidiaries of the Issuer (collectively, the “Guarantors”), including, without limitation, the Company, of the obligations of the Issuer under the Exchange Notes (the “Exchange Notes Guarantee”), covered by the above-referenced Registration Statement, and all amendments thereto (the “Registration Statement”), filed by the Issuer with the United States Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “1933 Act”). The Exchange Notes will be issued by the Issuer in exchange for $1,100,000,000 aggregate principal amount of the Issuer’s currently outstanding 5.625% Senior Notes due 2022 (the “Original Notes”) pursuant to a Registration Rights Agreement, dated as of July 16, 2014, including such joinders to date (collectively, the “Registration Rights Agreement”), by and among AmSurg Escrow Corp., a Tennessee corporation (“Escrow Corp.”), the Issuer, the Guarantors and Citigroup Global Markets Inc., as representative of the several purchasers named therein. This firm did not participate in the negotiation or drafting of the Registration Rights Agreement or the Indenture (as defined herein).

1. The Registration Statement and the related form of prospectus included therein in the form in which it was transmitted to the Commission under the 1933 Act;
