    Naturalist/Certified Photo Instructor
    R. Aaron Raymond started his career as an underwater photographer, which blossomed from his love of the ocean. He grew up on a sailboat diving for abalone off the coast of California. He loves to photograph landscapes, nature, and wildlife—anything that allows him to capture fleeting moments and showcase the interaction of light and the natural world. Aaron has photographed life on all sides of the planet, from the depths of Madagascar’s oceans to the heights of the Himalayas, which he crested at 18,500 feet via motorcycle.

  • Chelsea Behymer

    Naturalist
    Raised sea kayaking, surfing, and hiking on the Central Coast of California, Chelsea established both curiosity and comfort in her outdoor surroundings early on. After a field ecology course in California's Channel Islands exposed her to the dynamic roles people can play in social-ecological systems, she embarked on a lifelong journey to understand her place. Chelsea received her Bachelor of Science degree in Marine Biology from Hawaii Pacific University where she dove (literally) into coral reef research and explored the micro-scale connections within. Taking her knowledge from the research field, Chelsea has spent nearly a decade professionally communicating the big-picture implications of the 'little things' in variety of marine science and natural history topics onboard marine tour vessels around the globe.

It was there that she obtained a BA in journalism and film production while focusing on the marine environment.

  • James Coyer

    Naturalist/Expedition Diver
    It was Malle and Cousteau’s The Silent World, viewed in a dusty meeting hall on a wintry day in central Wisconsin that forged Jim’s dream and commitment to become a marine biologist.  Never mind that he was only 8 at the time and that it would be another 13 years before I finally felt the spray of an ocean on my face.

  • JIll Niederberger

    Naturalist
    Jill is an aquatic biologist, naturalist, divemaster, and captain with a love for everything living in and depending on water. Whether sailing catamarans, leading snorkeling tours, or assisting with cetacean field research projects, she enjoys connecting others to the wilderness around them. Her most recent adventures have led her into a focus on marine mammals – those creatures with fur and blubber that defy the odds by living in or depending on an environment in which they cannot breathe.

  • Sarah Friedlander

    Expedition Leader
    Growing up with a large backyard, Sarah spent her childhood exploring the woods and bringing home frogs. When asked not to bring frogs into the house, she learned the difference between frogs and toads and was soon asked not to bring toads into the house either. Raised just outside of Washington, DC, she considers herself lucky to have grown up with exposure to a combination of the outdoors and the city, as it helped her pick with certainty which one she wanted to spend all her time in - the outdoors.
