Peter Yarrow (center)

As an artist and activist, Director Peter Yarrow of Peter, Paul & Mary’s gifts are legendary. He has written some of the most moving songs that Peter, Paul & Mary have recorded, including “Puff, The Magic Dragon,” “Day Is Done,” and “Light One Candle.” This musical creativity has always gone hand-in-hand with Yarrow’s commitment to positive social change dedicating his time and talent over the years to equal rights, peace-building, education, preservation of the environment, and more. Just as Peter Paul & Mary used their music as a platform for advocacy, Peter has harnessed music to unite hearts in common purpose, knowing that when music brings people together, it has a unique ability to catalyze and hasten positive change.

Currently, Yarrow devotes most of his energies to Operation Respect (OR), an educational non-profit he co-founded over 20 years ago that took its inspiration from a song, “Don’t Laugh At Me”, written by Steve Seskin and Allen Shamblin. Peter brought the song to his trio partners who, like himself, were brought to tears by its powerful message. The DLAM program focuses on creating safe, caring, bully-free environments for children and is currently utilized in over 20,000 schools in the US and other countries such as Ukraine, Israel, Jordan, Palestine, Hong Kong, Croatia, Canada and Japan.  Says Peter, “We need to educate the hearts of our youth, not just their intellects.  Our children deserve to be given the tools to become good citizens who care about, and participate in, efforts to make their country, and the world, a better place.”

National Geographic Photographer - Brian Skerry

Brian Skerry, Director, is an award winning National Geographic underwater photographer, lecturer, and author who uses his international platform to draw attention to the many environmental problems plaguing the sea and offer hope through stories of the ocean’s resilience. Unique within the field of underwater photography is Skerry’s ability to pursue subjects of great diversity. His nearly year-round assignment schedule frequently finds him in environments of extreme contrast from tropical coral reefs to diving beneath polar ice. While on assignment he has lived on the bottom of the sea, spent months aboard fishing boats, and traveled in everything from snowmobiles to canoes to the Goodyear blimp to get the picture. He has spent more than 10,000 hours underwater over the last 30 years. Skerry frequently lectures on photography and conservation issues, having presented at venues such as TED Talks, Harvard University, the National Press Club in Washington, D.C., and the Royal Geographical Society in London. He is also a regular guest on programs such as NBC’s Today, CBS’s Sunday Morning, and ABC’s Good Morning America and devotes countless hours to marine conservation.

Cassieheadshot (1)Cassandra Bergeron, Director, has been in the water her entire professional career. She is a PADI Divemaster, WSI (Water Safety Instructor) Instructor, CPR Instructor, and was awarded the American Red Cross National Certificate of Merit, the highest certificate of merit for lifesaving, awarded by the President of the Red Cross in 2011. A little known fact about Cassie is that she was formerly a performance mermaid at the Silverton Casino in Las Vegas, where she was also a safety diver. She’s passionate about all animals and has been involved in animal rescue her entire life. She is originally from Texas and holds a bachelors degree in biology from New Mexico State University.

Laura McCallion, Board President and Director of Dive Education, is a PADI Course Director, the highest level of professional dive certification available. Laura has a passion for the ocean and the underwater world that began at a very early age. She was certified in the very cold waters off of Gloucester, Massachusetts over twenty years ago and despite the near freezing temperature and the fact that it was snowing, she has been addicted to scuba diving since. Since starting to teach diving in 2000, Laura has introduced hundreds of students of all ages to the amazing and wonderful underwater world of diving both in cold and warm water environments. Watching the expression on a new diver’s face when he breathes underwater for the first time or achieves something he wasn’t sure he could really do or when he encounters a marine creature he’s never seen before always reminds her of why she became an instructor in the first place and why she will continue to teach as long as possible. She has a special passion and talent for teaching diving to young people.

PeterHeadshotPeter G. Lewandowski, Assistant Director of Dive Education, is a PADI Staff Instructor with specialties in Deep, Dry Suit, Peak Performance Buoyancy and Wreck Diving specialties, to name a few. Peter started his career in the cold waters of New England and found a passion and love for being in the water and exploring the oceans that lead him on the path to becoming a Divemaster and eventually a Staff Instructor. He has traveled extensively from the Pacific to the Indian Oceans exploring remote locations, which has created a deep love for the ocean and the environment and for preservation of our water world. He enjoys teaching students and seeing the reaction on their faces when they take that first breath underwater and later as they continue to explore their possibilities. He hopes to create future ambassadors for the ocean environment. “I feel being in the ocean is like being an early explorer. The location you are in at that moment on that dive has never been seen by another person. You are the first explorer to view it,” Peter explains. “That speaks to vastness of the oceans and the potential we still have for its exploration, which I wish to instill in people so they have the same passion and love for the ocean that I do.” When asked where the best place is that he has have dove, he always responds: “find me a puddle deep enough and I will dive it.” The ability to explore is the drive that I want to instill in people to expand their view of this vast water world, and to connect them to the wonders that it holds and the need to protect it for all of us.
