A little more than two months after the deal to sell the Perseus Books Group to the Hachette Book Group USA and Ingram fell apart, Perseus CEO David Steinberger has implemented a restructuring aimed at streamlining the publisher’s operations to put more focus on execution.

As a result, Steinberger has created two new group roles, appointing Susan Weinberg senior v-p, group publisher and naming Mark Suchomel to the new post of president client services. Three executives will be leaving as part of the reorganization including Running Press publisher Chris Navratil.

Steinberger said that in his view the reorganization is the “best way forward to generate year-over-year growth.” He hopes by streamlining the corporate decision-making the company will be able to respond quicker to market opportunities. Before the reorganization, 12 people reported directly to Steinberger, that figure is now six. All Perseus’ publishing imprints and joint publishing ventures will now report to Weinberg, including Avalon, Basic Books, Da Capo, PublicAffairs, and Running Press. Suchomel will now oversee all of the company’s distribution operations, including Perseus Distribution, Consortium, PGW and Legato, the company Suchomel recently formed after his departure from IPG. The two appointments, Steinberger wrote to employees, give the publishing and distribution groups an executive who will focus directly on their needs.

Steinberger has also reached outside the company to hire a new senior v-p for operations, Raymond Floyd, whose background includes 13 years with General Electric. He will report to Perseus COO Charles Gallagher.

Other promotions include that of Matty Goldberg to the new role of president of publishing, client and sales development, while Sabrina McCarthy has been appointed senior v-p of group sales, taking Goldberg’s old post. McCarthy, who had headed up Perseus Distribution Client Services, is being succeeded in that role by Heidi Sachner. Jeff Tegge, who was Suchomel’s second in command at Legato, will now head that unit.

Steinberger said he has begun a search to replace Navtratil, who joined Running Press in April 2009. Until a replacement is found, Allison Devlin will serve as acting publisher at Running. The only other jobs eliminated in the reorganization were that of Patrick Kirk, who was a project manager, and Scott Edinburgh who was in business development
