MNS Publicity is an independent boutique book publicity firm specializing in conservative nonfiction, founded by Stephanie Marshal, Gwen Nappi, and Sandy Schulz. The agency has built one of the most concentrated specialty practices in U.S. book PR — focused on conservative-leaning authors, political commentators, and policy thinkers — and has worked on more than 60 New York Times bestsellers across its history.
Founding and ownership
The agency was founded by three principals — Marshal, Nappi, and Schulz — who built their experience inside conservative-leaning publishing imprints and political book publicity programs. The firm is privately held and independently owned. Sandy Schulz remains active as co-founder and is the agency's most visible public-facing principal.
Specialties
MNS Publicity's core practice is book publicity for conservative nonfiction authors, with adjacent services in author branding, media outreach, broadcast TV and radio bookings, podcast outreach, and long-cycle media campaigns supporting book tours and policy-shop launches. The firm operates as a communications-strategy partner across the full launch arc — manuscript-to-bestseller and beyond.
Notable authors and placements
The agency's roster has included Dr. Ben Carson, Rodney Stark, Peter Schweizer, David Lefer, Kim R. Holmes (Rebound: Getting America Back to Great), and Amity Shlaes (The Forgotten Man), among other conservative authors. Placements have included The New York Post, The New York Times, USA Today, The Wall Street Journal, and the major broadcast networks.
Position in the market
MNS Publicity occupies a distinct niche — the dedicated conservative-author book publicity firm — in a U.S. book PR market that is otherwise dominated by general-interest and progressive-leaning shops. The 60+ NYT bestseller tally is unusually high for an agency of its scale. For broader book PR coverage, see EPR's Nissen PR profile and the PR Firms Directory.
