Mobile Mini, the world’s leading provider of portable storage units and offices, last week said Lawrence Trachtenberg, its executive vice president and chief financial officer since 1995, will retire at the end of 1995 to spend more time with his family. Trachtenberg also served as Mobile Mini’s general counsel until June of this year. He will continue to serve on the company’s board of directors and will become a part-time advisor.

Mobile Mini said Mark Funk, managing director of Deutsche Bank Securities’ Structured Debt Group, will join the company to take over Trachtenberg’s position. Funk has worked with Mobile Mini’s finance team of several of the company’s key transactions in recent years, including acquisitions, debt offerings and expanded credit facilities, most recently with securing the company’s new $900 million asset-based revolving credit facility, which facilitated Mobile Mini’s June 2008 merger with Mobile Storage Group. Funk has spearheaded high profile structured debt transactions for Hertz, RSC Equipment Rental, NES Rentals and others.

Mobile Mini is based in Tempe, Ariz.
