Meet the Staff

Fred Sitkins

Executive Director (231) 271-3077 ext. 101

Fred Sitkins became our organization’s second executive director in 2013, but he was involved with ISEA during its infancy in the ‘90s. Before we had a ship of our own, we chartered the tall ship Malabar, which Fred helped crew! After receiving his Bachelor of Elementary Education and Masters of Educational Administration, Fred went on to become a teacher and later the principal at Boyne City Elementary. It isn’t often that someone has the opportunity to see his or her life come full circle, and Fred is excited to be at the helm of ISEA after it inspired him so early in life.

Outside of running the organization, Fred enjoys spending time with his wife and two sons playing hockey, fishing, sailing, and mountain biking.

Izzy Cooper

Program Coordinator (231) 271-3077 ext. 102
Izzy joined the ISEA team in 2021. Born and raised in Traverse City, Izzy has a deeply seated passion for the Great Lakes and is thrilled to be part of a community that cares about instilling that passion in others. Izzy holds a Bachelor of Arts from Michigan State University where she studied Arts & Humanities and Natural Resource Management. Prior to joining ISEA, Izzy worked as the director of a summer camp on the shores of Lake Michigan.
Outside of work, Izzy enjoys exploring new trails with her dog, throwing pottery and baking pies and other sweet treats.

Harrison Fischer

Marketing and Communications Coordinator 231-271-3077 ext. 109

Harrison first joined ISEA in the summer of 2022. He is originally from the Ann Arbor area; he spent many summers traveling up north, wading through creeks and getting lost in the woods. After graduating from Bowling Green State University, and helping to win a rugby national championship, Harrison decided the next step was to work in Outdoor Education where he found a love for teaching, working with kids, and paddling. After completing a Masters of Education in 2021 Harrison and his wife Nicole looked around trying to figure out where to head off to next. Traverse City seemed like the perfect fit, with career opportunities and the Great Lakes calling they took the leap and have loved every minute. 

When not at ISEA Harrison can be found playing ultimate frisbee, walking his beagle, or enjoying the beauty of northern Michigan with Nicole. 

Ben Hale

ISEA Captain (231) 271-3077 ext. 103

Ben was one of our early interns in 1997. After receiving his Bachelor of Zoology, he helped crew and sail tall ships not only in our Great Lakes but in the oceans as well. Ultimately, Ben came back to join our staff in 2012 because he believes in our mission of protecting the Great Lakes through education.

After a long day of captaining our schooner Inland Seas, Ben goes home to his wife and son (a practical carbon copy of Ben, we’re sure!) and daughter to relax and play the fiddle.

Lily Heyns

ISEA Captain 231-271-3077

Lily embarked on her sailing career in 2009, starting out as a deckhand aboard a Windjammer in Maine. During her early years, she sailed as far as Greenland and Puerto Rico. In 2013, seeking new adventures, she made her way to Traverse City to explore sailing on the Great Lakes, discovering a love for freshwater sailing.

Introduced to Inland Seas during the Spring Schoolship season of 2013 while working for schooner Manitou, Lily found it to be the highlight of the Manitou schedule. In 2018, Lily joined ISEA as a relief captain for their programs aboard schooner Inland Seas. With the growth of ISEA programming and the acquisition of schooner Alliance, Lily officially became the second full-time captain in early 2023.

When ashore, you can find Lily on walks around her property with her dog and cat, baking, and gardening.

Kate Jarvi

Office Manager (231) 271-3077 ext. 108

Kate moved to Traverse City in the fall of 2021 and is excited by ISEA’s mission. She has lived in a variety of places but has deep connections to Michigan, including many years of visiting grandparents in the Upper Peninsula. Curious by nature and with a Bachelor of Science degree from Michigan Technological University (1988), she looks forward to learning more about the Great Lakes from ISEA staff, volunteers and students.

Outside of the office, Kate loves hiking, exploring parks with friends and family, and making and appreciating art.

Julie Johnson

School Partnerships Coordinator (231) 271-3077 x107

Julie joined the ISEA team in May 2024. Growing up in Michigan, she has always loved all things water, whether that be swimming, scuba diving, snorkeling, or beach rock hunting. She attended Michigan State University for her Bachelor of Science in Zoology and her Master of Science in Community Sustainability. Prior to joining ISEA, she has held a variety of positions, including working as a research assistant in a limnology lab, a park ranger at Sleeping Bear Dunes with their piping plover crew, and as the coordinator for an ecology-based afterschool program for high school students in Benzie County.

In her free time, Julie can be found watching birds, gardening, cooking, laying on the beach, or cozying up at home with her husband, cat, and dog.

Juliana Lisuk

Associate Director (231) 271-3077 ext. 104

Juliana joined ISEA in 2019. Growing up in Leland, MI, she spent many hours in, on, or around the Great Lakes and is excited to return to her northern Michigan roots. Juliana received her Bachelor of Arts degree in Environmental Studies from Denison University and her Master of Science degree in Environmental Behavior, Education, and Communication from the University of Michigan School for Environment and Sustainability. She brings her past experience in the non-profit sector, environmental education, and coastal communities research to her job at ISEA.

Outside of work you can find Juliana exploring the outdoors through hiking, canoeing, and growing vegetables.

Rachel Ratliff

Volunteer Coordinator (231) 271-3077 ext. 106

Rachel earned a degree in natural resources management with a biology minor from Grand Valley State University in 2017. A year later she worked with Inland Seas as a Schoolship Education Intern. ISEA offers a unique opportunity to marry her knowledge of science and love of theater; the best sails come with a bit of dramatic flair! She is passionate about protecting the Great Lakes and inspiring the community to love our grand freshwater feature.

During her free time, you can find Rachel flipping her fins as a mermaid in the bay. She also enjoys chilling shore side cozied up with a book and her black cat.

Lauren Sheffer

Great Lakes Educator
Lauren is a recent graduate of the University of Michigan, where she double majored in Biology and Environmental Studies. Growing up right here in Leelanau County, she spent a majority of her childhood swimming in Lake Michigan and exploring many of the forests, dunes and inland lakes the area has to offer. She is passionate about stewardship within the Great Lakes region, and is excited to share her love for the region with others this summer.

In her off time, you can find Lauren hiking the nearby trails, checking out the local farmers markets, and loving on her two cats, Franklin and Leroy.

Chris Symons

Education Coordinator (231) 271-3077 ext. 105

Chris started with ISEA in 2024, and is thrilled to be back in his home state of Michigan. He attended Michigan State University studying Education and Environmental Science, before leaving the state for seven years to work as a Park Ranger for the National Park Service. He is deeply passionate about creating memorable experiences in non-traditional classrooms, from the Grand Canyon backcountry to sailing up the California coast on a 16th century Spanish galleon, and now at ISEA helping people find new ways to appreciate just how special our Great Lakes are.

Outside of work, Chris loves to enjoy everything the turning of the seasons has to offer, playing team sports, and doing his absolute best to appease his cat, Piccolo.
