MIAMI — Navarro Discount Pharmacies has named Steve Kaczynski as its new chief executive officer.

He succeeds Marcio Cabrera, who filled the role on an interim basis while serving as managing director of MBF Healthcare Partners, which owns the 28-store Navarro chain.

Before joining Navarro Kaczynski was president and chief executive officer of Bigg’s, a division of Supervalu Inc.

“We are very excited to have an individual with Steve’s leadership ability and retail expertise as the chief executive officer of Navarro,” Cabrera comments. “In addition to his leadership skills, Steve’s expertise in merchandising and marketing will be essential in the execution of the company’s future growth plans.”

Kaczynski has spent nearly four decades in retailing. After beginning his career in the grocery industry in 1970 at Martin’s Super Markets, Kaczynski went on to hold executive positions at Wild Oats Markets Inc., the Giant Food Stores (Giant-Carlisle) unit of Ahold USA, and Supervalu’s Cub Foods and Bigg’s.

Cabrera had replaced former owner and board member Gabe Navarro as CEO in 2007 after MBF, a private equity fund, acquired a majority stake in the drug store chain.

Then in August 2008, the company promoted Lee Armbuster, who had been hired by Navarro earlier in the year as chief operating officer, to the CEO position. Armbuster previously was president of Supervalu’s Shop ’n Save division.

By March 2009, however, Armbuster was out and Cabrera and Navarro had resumed direction of the company’s operations.
