Captain Tony Coulter
Captain Tony Coulter
Captain Tony Coulter was raised in Southeast Florida. Spending most of his youth playing the open seas, he is familiar with most reefs and wrecks in the area. As well as the well-known dive spots, Captain Tony has a few of his own secret spots that he is always willing to take adventurous divers, too.
As a licensed Coast Guard Captain and a PADI instructor for the past 35 years and an NAUI instructor, Captain Tony has maintained a standing reputation in the diving industry as a safe and friendly operator.
Karen Orsak
Karen OrsakDivemaster
Divemaster Karen Orsak has been working with Capt Tony for the past 30 years, and some of her charm has even rubbed off on him. Karen has been diving for 35 years and has worked as an underwater tour guide for almost as long.
Her favorite pastime is guiding divers along the pristine reefs of Delray Beach through Ft Lauderdale. She is forever searching for that record-sized lobster and more beautiful shells for her collection (she only takes empty shells, as she is an avid environmentalist!). Karen is also PADI Medic First Aid, and DAN O2 certified, as is all the crew aboard the Diversity.
