The Tikkun HaYam Team

Rabbi Ed Rosenthal


Born and raised in landlocked St. Louis, Ed’s passion for the marine environment can only be attributed to watching “The Undersea World of Jacques Cousteau” and reruns of “Sea Hunt” as a kid.  When he was 16 years old, he asked his parents if he could learn to Scuba Dive.  His mother’s response was: “If God meant for humans  to be under water, He would have given us gills.” So it wasn’t until a hiking trip in the Sinai during his first year of Rabbinical studies, that Ed had a chance to snorkel at Sharm el-Sheik.  There he heard the call of the Sirens.  When he returned to the US to continues his studies in Cincinnati, he finally got his scuba certification.  The Jewish tradition is filled with deep, spiritual teachings about water and the Sea, yet most Jews have not been exposed to this part of our heritage.  Ed wants to show the wonders of the underwater world through Jewish eyes, while raising awareness about the myriad threats it faces.  He believes that when Jews get involved in any issue, substantive change takes place.  Tikkun HaYam was created in order to get the Jewish Community involved to Repair the Sea.

Shayna Cohen

Digital Media Coordinator

Shayna Cohen is a PADI Master Scuba Diver Trainer, an SSI Century 100 Instructor, and #theseahugger.  Born in Hawai’i, growing up snorkeling and freediving, it is no surprise that Shayna is a marine conservation maniac. She originally obtained her SCUBA certification to complete fisheries management research in Turks and Caicos.  With a Bachelor's Degree in Biology from Grinnell College, Shayna spent some time sneaking marine conservation into her lesson plans as an educator before deciding that teaching SCUBA is the best way to create marine stewards. While working as a SCUBA instructor, dive guide, and Conservation Co-Coordinator at Rainbow Reef Dive Center in Key Largo, Shayna shared the wonders of the underwater world with hundreds of divers, pulled hundreds of pounds of debris from the water, and volunteered her time and skills with numerous environmental organizations. In 2017 she relocated to Tampa to expand Tikkun HaYam to new depths.

Josh Keller

Program Coordinator

Josh Keller is a Master Scuba Diver Trainer, certified to teach over 25 different specialty classes. Josh grew up along the Jersey shore, always being in the water. Working, playing, learning, whatever he did was based on the ocean. He eventually graduated from the Marine Academy of Science and Technology, a marine biology specialized school, as a Senior Chief Petty Officer in the NJROTC. He then attended Eckerd after falling in love with the Scubi Jew program, excited to combine his passion for the ocean and Jewish heritage. After spending two and a half years as the Scubi Jew president, Josh graduated Eckerd with a marine science degree and computer science minor. He left almost immediately for Key Largo to do an internship with Rainbow Reef, after which he was hired as an instructor, airboss, office staff, first mate, and guide. While in Key Largo, Josh taught many specialty classes about ocean conservation, and every dive for Josh is a Dive Against Debris. In 2020 Josh has returned to St. Petersburg to be the Program Coordinator of Tikkun Hayam.

Ellie Foden


Raised in Connecticut, Ellie didn't get most of her exposure to the ocean until she started diving with her dad at 10 years old. Her first dive didn't go according to plan, but the water managed to hold her interest, and after trying again, Ellie completed her Junior Open Water scuba certification. Two years later, she completed her Open Water certification and fell deeply in love with the mystery and beauty of the water. Before starting college, Ellie traveled to Madagascar and volunteered with a marine conservation NGO for three months where she participated in building an artificial reef, coral transplanting, and conducting scientific surveys. During this time, Ellie worked up to becoming a Rescue Diver. This hands-on work cemented her passion for conservation and carried Ellie into her first year at Eckerd College. Within her first month at school, she got involved with Scubi Jew and jumped right in. During her sophomore winter break, Ellie slept on her scuba instructors couch as she worked to achieve her Divemaster certification. As she finishes her senior year, she has worked her way through the club with hard work and passion, to now sitting as president and working alongside the Tikkun HaYam team as Intern.
