Catherine Eastman (Cat) has been working with sea turtles in Florida since 1998. Growing up on the Atlantic Coast (in almost every state), Cat has always had a love for the ocean and its inhabitants. She started her career with sea turtles while studying at Florida Atlantic University in Boca Raton. There, she joined the sea turtle conservation program at Gumbo Limbo Environmental Complex as a marine turtle specialist. She transferred to University of North Florida to finish her degree and accept an Environmental Educator position at the Guana Tolomato Matanzas National Estuarine Research Reserve. She taught environmental education to K-12 school kids and led beach and upland nature hikes to adults and undergraduates. During that time, she and her husband incorporated a conservation non-profit to help support sea turtle nesting beach work and research. When Cat is not working, she enjoys spending time with her husband and son (and golden retriever) at the beach and running.

Devon Rollinson

Sea Turtle Hospital Veterinary Technician
904-461-4025 |

Devon was born and raised in New England where she developed a passion for nature and wildlife at an early age. It was Devon’s mother, an active wildlife rehabber, who nurtured Devon’s curiosity and desire to help all creatures big and small. She attributes her love for the field to growing up alongside a variety of North American wildlife. “I spent my childhood with orphaned raccoons, squirrels and the occasional fawn.”

After receiving a bachelors degree in Wildlife Care and Biology from Unity College in Maine; she spent some time on a rock in the middle of the Pacific (Hawaii) working with dolphins and sea lions. “It’s every kid’s dream: to become a dolphin trainer.” This is what led her to realize that marine animal conservation and rehabilitation was her calling and true passion.

After relocating back to the main-land, Devon began her career as a veterinary technician. More recently, she has worked with members from a local animal hospital to help injured and ill wildlife before joining the Sea Turtle Hospital at Whitney Lab. She is excited to be part of the Sea Turtle Hospital ”Pioneers” and is looking forward to working within her passion.

Devon enjoys spending her “free time” (when not caring for sea turtles and a variety of other animals) with her fiancé Mike and their two “furry” children; both lab-mix rescues from local shelters, Henry Jones and Joshua David, her side kick, Chuck the cockatiel and a few other “friends” who were in need of a home.  She also enjoys traveling, hiking, camping and anything water related.

Ann Osborne, DVM

Sea Turtle Hospital Relief Veterinarian 

Dr. Ann Osborne graduated from the University of Florida College of Veterinary Medicine in 2008 and currently practices small animal medicine at Moses Creek Animal Hospital in St. Augustine. Her passion for conservation and marine life began as a child growing up in Brevard County, one of the busiest sea turtle nesting beaches in the country. She majored in wildlife conservation and ecology as an undergraduate at UF and developed a deep interest for scientific and clinical research. During veterinary school, her favorite patients were three loggerhead sea turtles she worked with while on her zoology clinical rotation. Ann enhanced her veterinary education with supplemental courses in marine mammal and reptile medicine, which fueled her motivation to work with marine life and pursue a research project studying sea turtle plasma protein levels. This work, published in the Journal of American Veterinary Medicine, remains the clinical standard for sea turtle blood protein reference ranges. Ann is excited and honored to be a part of the Sea Turtle Hospital team, helping to improve the health and rehabilitate sea turtles as well as gaining a better understanding of disease processes, including fibropapillomas in sea turtles through research. Ann lives in St. Augustine with her husband, two young daughters and two dogs.
