Madison Severy
Cruise Director
Madison grew up in Santa Barbara, California, spending her summers in the ocean. Her and her parents shared a love for traveling, and when she was 15 they got her open water certified at the Channel Islands. It took some time before cold diving grew on her, and after a family dive trip to Fiji, she was convinced this was the right sport for her.
After college, she wanted to make money while traveling, so she decided to move to Roatan, Honduras to complete her divemaster and instructor courses. After working for a year on the island, she traveled throughout South East Asia, working in Indonesia, then back home where she split her time working between California and Honduras as an instructor. In 2023, she began her career in the yachting industry, and eventually found her way onto the BVI Aggressor.Bradley Botha

Rob Peterson
Dive Pro
Rob was born in Sacramento California and grew up in the dessert mountains of southern Utah. After getting certified, Rob's first recreational dive was at the Catalina Island dive park which is where Rob's love of the ocean, travel and diving began.
Rob started working on Catalina Island as a Zipline tour guide but he always frequented the beaches and dive park during his off time. Once the season ended, his career would take him to the pristine shores of Juneau Alaska where he worked as a deckhand and naturalist aboard a whale watching boat.
With a newfound respect and admiration for the sea, Rob persued his Divemaster through an internship on the island of St Croix where he familiarized himself with the geography and ecosystem of Caribbean waters.
Still hungry for scuba diving, Rob entered the yachting industry after moving to Florida in search of day work and Divemaster positions where he would formally find his ocean ready home aboard the BVI Aggressor.Chun Chi Tsao (Queenky)
Cruise Director
Queenky was born and raised in Taipei, Taiwan and had an early introduction to working in the luxury retail industry. She then tried scuba diving in 2010, in Australia and felt very comfortable in the water! But scuba diving was never something she gave real thought to, until she started her open water course and realized there is so much to see underwater!
Chun Chi did her dive master in the Red Sea and after that she became an instructor in Taiwan where she also worked for two years.
Now, it’s a new chapter for her to work at aggressor BVI and to share her vast diving experience with Aggressor guests.
