Neven grew up in Montana and Wyoming and spent most of her landlocked childhood in the swimming pool where she fell in love with being in the water. In college, she had the opportunity to develop her initial scuba skills over an entire semester during her SSI Open Water course, although she didn’t truly fall in love with scuba and the ocean until several years later, as she had a fun and exciting professional mountain biking career in the interim. When she got back into diving, she really went for it, though, exploring incredible diving in Roatan, Egypt, Indonesia, Socorro, the cenotes in Mexico, and Cocos Island, to name a few. She really fell in love with the incredible oceanic ecosystem but most especially with corals and sharks. Additionally, given that Neven has her PhD in Chemical and Biological Engineering, it didn’t take long for the appeal of technical diving to draw her in, too, given the meticulous nature of the planning and calculations required for longer, deeper dives and cave diving.

Alisia Carlson (known as Al by fellow divers & crew members) started life in Panama City, FL and fell in love with the ocean as a child. Her first job was as a lifeguard and swim instructor and, no matter what state her family moved to, she found a way to be in the water. While lifeguarding in Mississippi one day, an instructor allowed her to do a quick scuba dive in the deep end. It was MAGIC!!! Years later, in Springfield MO, she was bouncing in and out of college and couldn't figure out what she wanted to do with life. She read a book that suggested thinking of the happiest fifteen minutes of her life and applying that to a career. Immediately that fifteen minutes in the deep end of a pool came to mind and she decided to be a dive instructor! After getting her open water certification in Key Largo she knew it would become her home. A couple of years and a lot of hard work later, she made her home in Key Largo and started building her life and career there. 

Life began for me in North Carolina, my dad was in the Air Force there. As a military brat I lived all over the country but I was always happiest by the ocean. From a young age I was always obsessed with animals, especially the aquatic kind. Being land locked in Missouri for my teen years I always longed for the ocean, weekends on the lake with the pontoon boat and my salt water aquarium would have to tide me over. My dad got me into diving when I was around 13yo, I was instantly hooked and my obsession grew. Eventually I joined the Air Force myself for a decade which lead me to falling in love with Key Largo, while stationed in Tampa i would make the drive down to dive every weekend! When the Air Force took me back to the Midwest, where I met Alisia, I decided to take a big risk, got out of the military, sold everything and made the move to key largo. It was/is a lot of hard work and a lot of trials but 10 years later we're still here! 

Emily was born in Wisconsin and grew up spending her summers at her family cabin on the river. This is where at an early age she developed a passion for the water through swimming, fishing, and boating. A family vacation to Mexico introduced her to the ocean for the first time where she went snorkeling and instantly became hooked as being face to face with the different fish felt like home. Later, a move to North Carolina allowed Emily to visit the beach every chance she could and she spent most of her time looking for shark teeth and seashells in the tide pools along the shore, now having a collection of almost 3,000 shark teeth! Fast forward to 2019 when Emily moved to Key Largo and hasn’t looked back since. The beauty and wonder of the Florida Keys encompassed her and further developed her passion for the ocean and conservation of our reefs, mangroves, and local ecosystems.
