Congratulations to Mareen Luethen (Berlin, Germany) who completed the Deep, Night, Peak Performance Buoyancy, Underwater Navigation, and Wreck Adventure dives this weekend, earning her a PADI Advanced Open Water Diver Certification. Mareen and I worked with Ocean Divers to explore the reefs and wrecks in Key Largo, FL. I had a great time diving with Mareen and her fiancé Victor, and I wish them all the best as they continue to dive together and learn new skills.
