Who We Are


Zach Brown, Co-Executive Director. Zach grew up surrounded by the wilderness of Southeast Alaska. With parents in the National Park Service, Zach had ample opportunity as a boy to explore the mountains and fjords of this region, experiences that gave him a lasting love of the natural world. Attending college in Southern California, Zach studied chemistry and biology. When the opportunity came to travel to the Arctic, his life changed forever. Zach spent a field season in the high Arctic archipelago of Svalbard, observing how seabirds are responding to a changing climate. This unforgettable experience led Zach to pursue a PhD at Stanford University, where he continued to study how changing sea ice affects the marine biological communities of the polar regions, especially the phytoplankton that form the first link of the food chain. During his time at Stanford, Zach was thrilled to undertake multiple research expeditions to the Arctic and Antarctic. Completing his PhD studies in spring 2014, Zach set off on a 4-month, 2300-mile solo trek, hiking and paddling from Stanford to his Alaskan homeland, to spread the word about creating Inian Islands Institute, now Tidelines Institute. zach@tidelinesinstitute.org

As co-executive director of Tidelines Institute and founding director of the Arete Project, she has worked with her students to create experiential and liberal educational programs that prepare students to be thoughtful stewards of the world around them. Prior to founding the Arete Project, Laura worked at Deep Springs College and as a ranger with the National Park Service. Laura has her B.A. from Yale University, her M.Phil from the University of Cambridge, and is a doctoral candidate at Stanford University. In her spare time, she is an avid backpacker, reader, and cook. laura@tidelinesinstitute.org

Matt Crowley-Miano & Nicole Schaub, Homesteading Residents, Inian Islands Campus  Believers in the power of nature to inspire meaningful change, Matt and Nicole are excited to join Tidelines Institute. They met working as park rangers in Glacier Bay National Park, where they spent many years developing their shared passion for Alaskan wilderness, wild foods foraging, and climate change communication. Between the two, they have conducted scientific research in Sweden and Cambodia, been environmental educators with the Peace Corps in the former Soviet Union, worked as teachers in South Korea and the Caribbean, led backcountry trail crews on construction projects throughout public lands, and lived together on a sailboat. They were last found managing a remote off-grid ecolodge in Tanzania. Hailing from Washington and Connecticut, they are looking forward to living close to the land, developing and learning homesteading skills, deepening their connection to Southeast AK, and bringing their enthusiasm for education and environmental conservation to the Hobbit Hole.

Amy Erfling, Garden Educator, Good River Campus. I am originally from Boulder, Colorado and moved to Southeast Alaska in 2011. I began working semi-professionally in the green industry in my early college years in Boulder, where I graduated with a B.A. in Germanic Studies. After graduating, I continued to work in the green industry and realized how much I enjoyed working with plants and landscapes. I returned to college to receive a B.S. in Landscape Horticulture in 2006 from Colorado State University. I’ve worn many hats as a landscape designer and horticulturalist, which brought me to Skagway in 2011. Skagway is where I realized the importance of a local food supply and I have been growing fresh, local produce in Southeast AK ever since.

Ellie Henkemeyer, Local Foods Educator, Good River Campus. Inspired by the incredible growth and richness that can come from living intimately with the land, Ellie has spent the past four years and over 400 trail days as a canoe and wilderness therapy guide in Canada, the southwest US, and Alaska. She is impassioned by the simple things in life that bring people together: laughter, authenticity, physical labor, and food. Since moving to the Great Frontier, Ellie has excitedly soaked it all up like a sponge, especially that which can be eaten and shared. Catch her foraging for greens along the beach, making salmon chowder and halibut burgers in the kitchen, or enthusiastically dancing by herself in her cabin. ellie@tidelinesinstitute.org

Tanner Horst, Campus Director, Good River Campus. Tanner is an educator who has worked at a variety of experiential and community-based schools as a teacher of manual skills, a maintenance person, and administrator. He is a graduate of Deep Springs College in California and Bowdoin College in Maine. He believes that learning to care for the physical world is more a feat of imagination than some type of knack, and that learning this care can help us to reimagine our habits, futures, and communities. tanner@tidelinesinstitute.org

Erin Ohlson, Administrative Guru. Erin and her husband Travis were born and raised in remote Alaska, and are now raising their own daughters similarly because of the sense of harmony and community that’s possible when living in such a place. The opportunity to be a part of something that fosters and teaches these values with the next generation of leaders is what drew Erin to work with Tidelines Institute. Erin received her master’s degree in public administration from the University of Alaska Southeast, and she spends her free time playing board and card games, traveling the world, and spending time with her family. erin@tidelinesinstitute.org

Morgan Peterson-Park, Kitchen Manager, Inian Islands Campus. Hello! My name is Morgan and I am the fun around here. I am the resident cook but never shy away from helping out where I can. My love for cooking began at a young age with my mother making meals for our large family. Graduated from the school of hard knocks, got a masters degree in kicking ass and a phd in taking names. I have lived in Southeast Alaska for the last seven years. I love my job and am one of the luckiest people in the world. I like getting students excited about cooking and bringing people together with food. Sharing meals with the people you love in a beautiful place, it’s what life is about. petersonpark24@gmail.com

Sage Logan, Alumni Representative. I am Lingit of the Kiks.adi and I came to Alaska from Bremerton, Washington to learn about my rich heritage. At University of Alaska Southeast I am majoring in Accounting and have minors in Tlingit language and Alaskan Native Studies. I decided to run for a board seat because of my experience at the Arete Project’s Glacier Bay Session. During my time I learned extensively how to live off the land and the privilege of subsistence living. I believe this lifestyle is heavily ingrained in Indigenous values, something I heavily support in all curriculum. I hope to offer both traditional values ideals and financial opinions that are heavily based around equity while serving on the Arete Project Board. Currently, I am working as a finance intern for Sealaska Corporation and in my free time I enjoy reading about finance and investing as well as researching sustainable ways to invest and how I can tie my cultural values into investments.

Hank Lentfer. I believe the quickest way to connect with the land is to eat it. Gardening, hunting, and fishing transform food from groceries to gifts. Through writing, recording wild voices and mentoring new arrivals to Alaska, I’m dedicated to helping others sense their connections to each other and the earth. I’ve spent all of my 50+ years here. Along the way, I’ve learned to pound nails, smoke fish, and a suite of other homesteading skills.  I’m eager to share them all with the students of Tidelines Institute.


Jessica Lindmark. Jessica first traveled to Southeast Alaska in 2003. She came away from that trip filled with a sense of awe for Alaska’s powerful landscapes, its creatures, and its enduring wilderness. She is thrilled to work with Tidelines Institute to bringing this experience to students and researchers, and to give back to this incredible part of the planet. Her formal background is in English, communications, and editing, which she often puts to service for startup projects, particularly those related to sustainability.
