Brian Gagas

Co-Organizer and Master Scuba Diver Trainer/Manager/Owner

Brian has been an outdoor enthusiast his entire life. He loves adventure and keeps it simple by making sure he is enjoying life no matter where it takes him. Brian discovered one of his greatest passions, scuba diving, only 7 years ago. He has been diving 3-5 times a week since. Through diving, he found his latest passion, teaching. This quote one from one of his many students sums up Brian's teaching style: "The Open Water certification with Brian Gagas was the best. He's focused on what you need to know with the patience that is needed in an excellent instructor. After 10 minutes, it's easy to see that he cares about you succeeding, not just teaching class after class. He goes above and beyond; the better the teacher, the better the student."

Cameron Conner


Cameron is from South Carolina, loves being on the water and wouldn't trade it for anything. Cameron started diving after being encouraged by a friend back in 2010. From the first year of diving, he started moving up in certifications and wanted to become a Divemaster to encourage others about what it's like to be in/near the ocean. Along with that, he loves spearfishing, being outdoors and living the dreams.

Dave started scuba diving in 1992 and continues to enjoy learning as much as possible about all aspects of scuba diving. Since Dave makes his living as a Firefighter and Paramedic it was only natural that he has gravitated to the rescue side of scuba diving.

Joe obtained his Dive Master certification with Gold Coast Scuba and comes to Gold Coast with a history of excellent customer service.
