BARBERTON, OHIO – Significant growth during the past half-decade means custom compounder Preferred Compounding will now have two executives managing sales, business development and customer relationships. Preferred is the second largest custom compounder in North America.

Scott Lieberman has been promoted to executive vice president for Preferred Compounding Corporation and president of Preferred Compounding de Mexico and will assume companywide responsibility for all customers with operations in Mexico as well as having P&L responsibility for Preferred’s operations there. Marc Pignataro, who has more than two decades experience in the chemical, metal, polymer and rubber industries, has joined the company as vice president of sales and business development and will manage sales for most of the U.S.

“Scott and Marc are highly capable leaders with deep industry experience and real commitment to the quality of our relationships we develop with new and existing customers,” said Ken Bloom, Preferred president and CEO.  “With them, we expect to continue to earn business by focusing on excellent fundamentals while delivering added value for each customer.”

Pignataro is replacing Joe Hudson, who will retire in mid-June of this year. Hudson has been elected to the board of directors and will continue to serve as an adviser to the company. He joined Preferred in 2008.

Lieberman joined Preferred as vice president of strategic initiatives in 2011 and became general manager for Preferred Compounding de Mexico in 2012 when the company acquired that operation. Since then, the Mexico operation has expanded twice and Preferred revenues overall have doubled.

He will also manage sales for the Southwest U.S. He will continue to split his time between Mexico and his primary office in Ann Arbor, Michigan.

“Everywhere I represent Preferred, companies have welcomed the flexibility with which we are willing to serve them and our commitment to quality and support,” Lieberman said. “I’m looking forward to continue to expand and enhance the added value the Preferred team can bring to the table for each customer.”

Pignataro will also report directly to Bloom and will have his office at the Barberton headquarters. Reporting to Pignataro will be the regional sales managers for the North, Central, Midwest, MidSouth and Southeast territories in the U.S.

“This is an exciting time for Preferred,” Pignataro said. “I am looking forward to building on what Joe and everyone at Preferred have accomplished by continuing to focus on servicing the customer while executing the growth and expansion targeted as a platform company for Audax Private Equity.”

Pignataro joins Preferred from SRC Worldwide, a leading global producer of premium magnesium fluxes and anhydrous magnesium chloride, where he was president & CEO. He previously worked for Flow Polymers, a manufacturer of proprietary and custom chemical dispersions, process aids and homogenizing agents and was a key member of the leadership team at Excel Polymers for a nearly a decade, including serving as president and general manager for operations in China.

He also worked for Ferro Corporation, which supplies glass-based coatings, pigments and colors and polishing materials, and at tire maker BF Goodrich in a variety of sales and technical positions. Pignataro earned a Bachelor of Science degree in Chemical Engineering from The Ohio State University and a Master’s in Business Administration from Baldwin-Wallace College.

Lieberman was North American sales manager for Excel Polymers before joining Preferred. He also served as director of automotive sales for Schaeffler KG, senior account manager and several other positions for Freudenberg-NOK, applications engineer for Bates Fabricating and as a manufacturing process engineer for Ford Motor Company. He earned a Bachelor of Science in Mechanical Engineering from Lawrence Technological University.
