Rachel LeCates

Environmental Educator | Certified Interpretive Guide (NAI)       Media Inquiries

My name is Rachel LeCates and I was born in Tegucigalpa, Honduras. I moved to York, Pennsylvania when I was eight years old. My love for science and the environment started at an early age. I distinctly remember reading Al Gore’s An Inconvenient Truth in 7th grade and deciding, “I gotta do something about this!” I graduated with a B.S. in Marine Biology from the University of North Carolina Wilmington. One of those semesters I studied in the Galapagos Islands; this experience cemented my passion for conservation and transformed my perspective on the relationship between humans and their environment. In 2019, I was both a summer and winter intern here at Sea Turtle Inc. I was then hired as a staff member in the education department in January of 2020. I am delighted to continue working with sea turtles and this amazing organization!

Favorite sea turtle species: I truly love them all but I have a soft spot for greens only because they’re the first species I encountered in the wild. I also particularly enjoy their adorable, grumpy faces. 

Kathryn Martinez

Assistant Giftshop Manager | Media Inquiries

I was born in Holland, Michigan and raised in Port Isabel, by a single father. I’ve known South Padre Island’s waters all my life. I have always had a fascination with the wild life this area has to offer as it is very diverse. 

After graduating high school I moved northward to Dallas, Texas where I lived for twelve years and though I loved it, home always calls you back. I am extremely happy that my son and daughter will gain great enjoyment from this area as I did. Nothing beats a walk on the beach and sea turtles hatching nearby.

I immensely believe in the conservation of not only our lands but also our coastal ecosystem. After 20 years in retail/customer service, I finally found an opportunity to contribute to both my passions. It is a wonderful feeling to be part of something that makes a difference to wildlife and connecting with people. They say the eyes are the windows to the soul, but have you ever looked deep into a sea turtle’s eyes? 

Favorite Sea Turtle Species: I have never been able to choose a specific turtle. I have always been fascinated with all species, but I do believe the Kemp’s Ridley holds a special place in my heart as it is the turtle we grew up coming in contact with. FYI, did you know that the Kemp’s Ridley females nest in South Padre Island? 

Mariana Devlin

Conservation Coordinator | Media Inquiries

I had the honor of being an intern for Sea Turtle, Inc. in the summers of 2009 and 2010 as I worked for my Bachelor’s degree in Wildlife and Fisheries Science from Texas A&M University in College Station. After my graduation, I worked in Costa Rica as a research field assistant in the Osa Peninsula where I fell in love with sea turtles even more. Upon my return to the US, I lived in Corpus Christi for 2 years while I obtained my Master’s degree in Environmental Science from TAMUCC, and I spent another 2 years working as a 7th grade Life Science and 8th grade Biology teacher. I love my job at Sea Turtle, Inc and always look forward to nesting season.  

 Favorite Sea Turtle Species: I love all sea turtles but I will always have a soft spot for the Kemp’s ridley and Olive ridley since I have been directly involved in their conservation efforts.

Mary Duncan

Volunteer Coordinator | Media Inquiries

I am from St. Louis, MO, and have wanted to work with sea turtles since I was in first grade! I have my Bachelor’s degree in Biology from NWMSU which included classes in Mexico and Australia to learn more about the sea turtles and marine life. Since then I have worked with the sea turtles in various places around the world, and I am super excited to share my experience with all of you here!

Favorite Sea Turtle: Leatherbacks are my favorite! Their anatomy and physiology are the most interesting, allowing them to migrate the farthest and dive the deepest. Though the leatherbacks are my favorite, I am super excited to be in the home of the Kemp’s Ridley, the most critically endangered of all the sea turtles!

Christopher Gorman

Rehabilitation Specialist | Media Inquiries

I graduated with a B.S. in Evolution, Ecology, and Biodiversity from UC Davis. I’ve always had a passion for working with wild animals and knew from a young age that I would follow my dream to make it a career. 2016 was an amazing summer when I worked at the Oakland Zoo as the commissary/night keeper intern. I worked with some truly amazing animals including baboons, elephants, tigers, tortoises, sun bears, and giraffes, as well as many other species. The fall seasons of 2016 and 2017 were spent working for Ducks Unlimited out in the Sacramento Valley. I started at Sea Turtle, Inc. in the summer of 2017 as a summer intern, and continued through the winter as a rehabilitation intern. Since being at Sea Turtle, Inc. I’ve been able to work with Kemp’s ridleys, Atlantic greens, Hawksbills, Loggerheads, and even a Leatherback! I’ve had some amazing adventures here at Sea Turtle, Inc. and I love my position in the hospital as the rehabilitation specialist.

 Favorite Sea Turtle Species: Kemp’s ridley. They are the feistiest of the turtles and look like modern-day dinosaurs. I love watching them hunt blue crabs (their favorite live prey).

Maria Watson

Aquarist | Media Inquiries

I was born and raised in Beaufort, South Carolina. My family immersed me into the coastal lifestyle (shrimping, crabbing, fishing, watching native wildlife, and doing beach clean ups), which is where I grew my love for our ocean and environment. That love continued as I received my Bachelors degree in Marine Science in Jacksonville University, Florida. During college, I pinpointed that I wanted to work in a rehab setting, particularly with sea turtles. My affinity for sea turtles grew when I became a rehab intern at Karen Beasley Sea Turtle Rescue & Rehabilitation Center in NC. That internship changed my life internship, I started the “I Skip the Straw” campaign from Ocean Conservancy on my campus and now our campus is completely straw free, excluding one of the outside restaurants! (All for the turtles & spreading awareness!) 

After college, I started my career at the Jacksonville Zoo & Gardens in education. I interned through their manatee rehabilitation which deepened my passion for rehab. I then became an Aquatics Keeper, where I was in charge of 4 species of stingrays and Lionfish. 

Favorite Sea Turtle: I am beyond excited to be here as the new aquarist and spending my days around the sea turtles and coworkers that carry the same love for them too! My favorite sea turtles has to be the loggerhead. I think the patterns on their heads look like cinnamon rolls and that is what makes them so sweet!
