Dan Abbott

Director, Kelp Forest Program

Dan’s fascination with kelp forests started when he was a kid, abalone diving in the lush forests in Northern California. Later at UC Berkeley, he continued to pursue this interest in ocean management by studying Environmental Economics and Policy, an interdisciplinary program that combined both scientific and economic aspects as well as by undergoing scientific diver training. After college, Dan put his skills and passion to work by volunteering with Reef Check. Today Dan is now the director of the Kelp Forest Program at Reef Check and is returning to monitor some of the same sites he used to dive as a kid — some of which have changed dramatically — and hopes that through his team’s work he can give scientists and marine managers the tools they need to protect and restore these ecosystems. Recently he has been working to expand Reef Check’s work preserving these ecosystems into areas of Oregon and Washington that are experiencing their own changes. Dan oversees the Reef Check Dive Program, is a member of the UCSC Diving Control Board, an active NAUI Instructor, and an Outdoor Emergency Care technician.


Annie Bauer-Civiello

Director, Restoration Program

Annie Bauer-Civiello is originally from Texas but discovered her love for the ocean at the age of eight. After moving to California, she received a Bachelor of Science in marine biology from the University of California Santa Cruz, where she also received all her dive training. During the last year of her degree, Annie studied abroad at the University of Queensland in Australia where she began to intern as a Project Officer for Reef Check Australia. After a brief stint with California Fish and Wildlife, Annie returned to Australia for her Master of Science in marine biology and PhD in environmental science at James Cook University. While studying, Annie worked as the Great Barrier Reef Survey Coordinator for Reef Check Australia, where she led scientific dives, marine debris clean ups and outreach events. After finishing her PhD, Annie then became the Executive Officer of a local NGO, working closely with the Australian Government, research institutions, community organizations and industry groups to improve waterway health in the Great Barrier Reef catchment. After nearly a decade in Australia, Annie has recently returned to her roots in California. She is very excited to bring her wide range of experience and knowledge to assist the Reef Check Foundation and the Restoration Program. 


Jenny Mihaly

Operations Manager

Jenny Mihaly, born and raised in Southern California, graduated from UCLA with a Bachelor of Science degree in Marine Biology after studying for a quarter at Bodega Marine Laboratory in Bodega Bay. She began her Reef Check journey as a student at UCLA and currently works out of Reef Check’s headquarters office in Marina del Rey.

Dillon Dolinar

Southern California Regional Manager

Dillon Dolinar began diving in Southern California in 2016 while attending San Diego State University where he earned a Bachelor’s degree in biology with an emphasis in zoology. This discovery of scuba diving inspired Dillon to join Dr. Matt Edwards’ kelp forest ecology lab where he worked on projects in San Diego, Catalina Island and Carmel Bay. During this time, he gained a love of kelp forests and the organisms who call them home. Upon graduating in 2020, Dillon joined the Reef Check family as the SoCal Volunteer Coordinator and now serves as the Southern California Regional Manager. In addition to doing field work, he enjoys analyzing Reef Check data to identify how rocky reef communities vary across space and time. He is consistently amazed by the community of Reef Check volunteers and all that they have accomplished.


Maxwell Seale

Central Coast Regional Manager

Maxwell Seale received his Bachelors in Marine Science from the California State University, Monterey Bay. Before beginning his work with Reef Check he founded the Underwater Voyagers Dive Club in Monterey, California that now hosts several hundred Central Coast Divers. Maxwell has spent the past several years conducting subtidal field surveys as an AAUS Scientific Diver. At Stanford University’s Hopkins Marine Station, he spent two field seasons as part of a team of divers researching kelp forest community oceanography. In his final year of college, Maxwell completed his capstone project leading numerous fish transects at multiple Reef Check survey sites spanning the coast of California. Maxwell also served as a scientific consultant for a satellite tag manufacturer, tracking the movement of pelagic predators and testing experimental hydrophones used to monitor whale migration. He also worked on piloting the use of experimental sonar based fishing equipment to end the whale entanglement crisis. He has nine years of experience in marine science education and outreach. When he is not in office, Maxwell spends his days diving in Big Sur and volunteering as a scientific mentor for Bechtel Education Center’s Teen Researchers Program at the Monterey Bay Aquarium. Above all else, he is passionately driven by the urgency of California’s declining kelp forests.

She moved to Northern California to attend Humboldt State University, where she received a BS in Climate and Energy Environmental Science. Morgan dabbled in environmental activism in New Zealand, which led to her interest in supporting conservation and resource management. She furthered her diving career by working as a PADI Divemaster in Honduras where she assisted reef conservation efforts to eradicate an invasive species of Lionfish. She also became an AAUS scientific diver and NAUI Instructor. Morgan worked as an at-sea observer collecting data on commercial fishing vessels for NOAA that contributed to the conservation and management of our fisheries. Morgan has been observing and filming the shift in Northern California’s rocky reefs and her videos have been displayed at the Noyo Center for Marine Science in Fort Bragg for public education and awareness. She is elated to be contributing to restoration and conducting long-term assessment of California’s vital kelp forest ecosystem.


Ian Norton

Northern California Survey Coordinator

Ian Norton grew up free diving off the coasts of his hometown in Fort Bragg, California. He received his bachelor’s in Environmental Science: Climate and Energy from Humboldt State University. After graduation in 2013, he discovered SCUBA and never looked back. From diving for abalone as a kid, becoming a Dive Master at Utila Dive Center in Honduras, and an active NAUI Instructor in Washington, the protection and conservation of the world’s oceans has become increasingly important to him. He worked for the Noyo Center for Marine Science in Fort Bragg producing video documentation of the urchin population explosion and early efforts to remove urchins. His videos are on display at the Noyo Center, to enhance public education on the topic. After receiving his AAUS certification from Moss Landing Marine Laboratories, he began work with Reef Check in 2020 and is excited to monitor the purple urchin situation on the Mendocino coast.
