Dear Mr. Wilson:

On behalf of PDI, Inc. (the “Company” or “PDI”), I am writing in response to the comments made by the staff of the Securities and Exchange Commission (the “Staff”) in its letter dated July 3, 2013 (the “Comment Letter”) with respect to the Company's Annual Report on Form 10-K for the year ended December 31, 2012 (“Form 10-K”) and, incorporated by reference, the Company's Proxy Statement for the 2013 Annual Meeting of Stockholders (“Proxy”). The Company respectfully acknowledges receipt of the Comment Letter and requests that the Staff grant an extension for PDI to respond to the comments on or before August 1, 2013 (an additional 10 business days) in light of the Company's recent and ongoing preparation for its upcoming Form 10-Q filing (and related Board of Directors and Audit Committee meetings). We hope the Company's request will be acceptable to the Staff, and will graciously accept any accommodation the Staff can provide.

Please contact me directly (phone: (862) 207-7832; facsimile: (862) 207-7899) if you have any further questions or concerns.

Yours truly,

/s/ Jeffrey Smith
