When Otis Wragg and Ray Casas started their Miami public relations firm in Aug. 1991 they wrote the first draft of the business plan on the back of a napkin. Even then Wragg knew that Casas was eventually going to take over the firm Wragg & Casas.

The only question was when? That day will come the end of this month.

Otis Wragg and his wife Joanna, who also is a principal in the firm, have announced plans to retire. Casas will buy out their equity shares. But the firm will keep the same name and Casas has no plans to bring on another partner.

“There’s value in the brand,” Casas said. “The firm will move forward without any other changes.”

Over the course of the firm’s history, Wragg & Casas built its reputation for handling crisis communication, corporate communications and public outreach campaigns. Some of their major clients included U.S. Sugar, Florida Marlins, Baptist Health and Shutts & Bowen. At its peak the firm had billings of $3.7 million a year and about 25 employees. Today the firm is still one of the ten largest in South Florida.

Otis Wragg and Casas had agreed from the beginning on one principle, they had to be in agreement on any clients. They lived up to that principle throughout the firm’s history.

“The rule was we do what we agree on and we don’t do what we don’t agree on,” said Wragg, who will remain as a consultant.

Wragg, 72, and his wife Joanna, 70, plan to spend more time traveling and with their two grandchildren.

“You begin to realize that other things are pulling at you,” Joanna Wragg said. “It’s time to shift the focus in a different direction.”
