Mark Senini, a member of a multigenerational lettuce and vegetable growing family in Yuma, Ariz., died July 17 of a heart attack. He was 54.

Senini worked for his family’s Yuma-based business, said George Braun, a Perishable Agricultural Commodities Act attorney and childhood neighbor of Senini’s.

Senini, the son of longtime Yuma lettuce grower Edward Senini, had been active in the Washington, D.C.-based United Fresh Produce Association, Braun said.

“He was a great guy,” Braun said. “He’d give you the shirt off his back.”

Survivors include four children: Katherine, Jennifer, Natalie and Alex; his parents, Edward and MaryJo; and several siblings.

He was preceded in death by his wife, Susan Johnson.
