Lindsey Homa M.P.S.
Program & Volunteer Coordinator / Wildlife Educator

Lindsey was a feather in the wind, living in Arizona, California, Florida, Massachusetts, and Ecuador, but was born and raised in Madison, Wisconsin. She attended Arizona State University and, after completing 3 years studying as a pre-health major, decided to stop ignoring the inner voice calling her toward a career in marine science. She switched her major, met an inspiring professor/mentor, and graduated with her bachelor’s in Biological Sciences with an emphasis in Neurobiology, Physiology, and Behavior from Arizona State Univeristy in 2019.

Lindsey next pursued a master’s degree in Marine Mammal Science at the Rosenstiel School of Marine, Atmospheric, and Earth Science, holding a variety of leadership roles and heralding strategic campus community initiatives. Her research focused on the intersection between tourism, sustainability, and the environment on Isabela Island, Galápagos, Ecuador where she spent 3 months surveying tourists and local Galapagueños (i.e., people of the Galápagos).

Lindsey has extensive experience in the non-profit sector promoting cultural awareness, sustainability, environmental and wildlife education, and conservation and rehabilitation of marine animals. Returning to Florida she began her next chapter working with her former professor and advisor, Dr. Griffin.

Lindsey is very outdoorsy and soaks up the sun whenever she can - whether hiking, paddle boarding, shelling, or anything at the beach. She also enjoys cooking, traveling, making art and jewelry, and spending time and with her dog. She speaks conversational Spanish and aims to utilize the language to expand programming at the Nature Center.

Marlie Rivera M.P.S
Wildlife Educator & Care Specialist / Assistant Volunteer Coordinator

Marlie was born in Newport News, Virginia, where she lived her entire life until relocating to Florida! Her journey into marine science began at the age of 6, inspired by a memorable trip to Turtle Bay in Hawaii. From an early age, Marlie exhibited a passion for wildlife and nature, often engaging in family camping trips, beach outings, and visits to local parks.

She developed a profound love and understanding of wildlife in her adolescent years and following grade school, spent the next 3 years studying biology at Old Dominion University in Norfolk, Virginia. In this time, she gained experience in a variety of environmental monitoring tactics, biodiversity surveys, and spent time researching the residence time of a common marine bacteria on microplastics.

After earning her Bachelor of Science in Biology in 2023, Marlie attended the Rosenstiel School of Marine, Atmospheric, and Earth Sciences at the University of Miami. There, she specialized in marine mammal science, expanding her expertise while contributing to public marine conservation outreach initiatives. Her efforts included planning and implementing events designed to engage and educate the public about marine conservation.

Marlie graduated with a Master of Professional Science degree in Marine Mammal Science in 2024 and now dedicates her career to advancing public awareness and education in conservation, driven by her enduring passion for the ocean and the interconnectedness of nature! Marlie enjoys spending her free time outdoors, searching for seashells along the beach, playing with her dog, and engaging in various creative, hands-on projects

Jennifer Ripley, M.Ed.
Operations Coordinator

Jennie was a naturalist from her earliest years. She grew up exploring the woods around her home in Connecticut and spent endless hours searching for salamanders, snakes, and pretty flowers. At age 13, she went on a whale watch off the coast of Cape Cod where she got the chance of a lifetime to observe an endangered Northern Atlantic Right Whale mother and her newborn calf. Even though it was a rainy cold afternoon, Jennie sat on deck for hours with the biologists soaking up the information they were excited to share. This moment furthered her love of nature and desire to help conserve it.

After earning a Bachelor’s degree in Child Studies and then a Master’s degree in Early Childhood and Special Education from the University of Saint Joseph, Jennie spent over twenty years in the nonprofit world creating and leading impactful programs that helped thousands of people across multiple states. During her travels she spent all her spare time exploring the ecosystems of the places she visited including California, the Midwest, and Hawaii.

After moving to Hobe Sound, Florida she explored the Nathaniel P. Reed National Wildlife Refuge beach nearly every day for months and decided it was time to do what she was passionate about her entire life - nature and conservation. Jennie volunteered with Loggerhead Marinelife Center as a hospital interpreter and conservationist on Juno Pier and took several Florida Master Naturalist classes through the University of Florida. Blending her background in education and non-profit management with her passion for conservation she is dedicated to advancing conservation through education. In her free time, she enjoys finding treasures on the shoreline, hiking in the inland preserves, and soaking up the natural beauty of her coastal community with her four beautiful children.
