Sara & Ripley

Sara Siegler,  Executive Director   (541) 937-3351 ext. 207

Sara is a new arrival to the Lost Valley Education and Event Center and its Community of staff, students and guests. Sara originally hails from California, but has lived throughout the U.S., Asia and Europe… often in community with others. She has several degrees and has worked professionally in the fields of education; media and marketing; and business and communications law.

Sara is passionate about life-long learning, and learning for longer living. So for her, becoming Executive Director of an educational center like Lost Valley, dedicated to whole-person sustainability on a personal, social, ecological, economic and global level, is an ideal made real. She is eager to work with and for the Community and all those it serves. And in her spare time? You’ll find her and her faithful big-red-doggy companion hiking one of the many gorgeous trails that wind through Lost Valley’s amazing 80-plus acres of permaculture projects, sustaining gardens and natural wonders.


Colin Doyle


Colin Doyle,  Education Director, Events Director   (541) 937-3351 ext. 202

Colin grew up in Massachusetts, but has experienced very much beyond that. He has degrees in    anthropology and religion, has worked and studied in Sub-Saharan Africa for a total of 15 months, lived in a tiny indigenous village in South America for nearly a year, and has traveled or worked in various other places.  Most recently he taught environmental education to 5th- and 6th-graders in the mountains of New Hampshire and Southern California, and led backpacking, canoeing, and other trips with teenagers for three summers.

Colin came to Lost Valley in the fall of 2010, and for four years has been the director of education.  This now means the Internship Program, Permaculture Design courses, and EarthQuest youth program.  He also handles outside groups renting the facilities for their own programming — the conference center (Events) business.  Colin is a crucial part of the core team of staff members that makes Lost Valley possible.

In his spare time, Colin likes stimulating conversation, learning about and experiencing different places, athletic activity, and hiking up big mountains to see amazing views.

Elsa (Elizabeth Erkel), Hospitality Lead: Dormitories

Elizabeth Erkel


Elsa was born in Frostbite Falls Minnesota a smidgen over 30 years ago — or so her mother and father claim. She was always the “not-athletic” one growing up and for the first time ever is having a blast discovering all the cool things her body can do even though, according to aging dogma, it’s supposed to be on the decline.

She studied photography in her early 20’s at Columbia College, Chicago after attending a high school called “The Zoo School”, which explains a lot. She has been to a handful of countries across the globe and doesn’t plan to stop there. When the time is right, the globetrotting will once more commence. Right now she is enjoying letting the world come to her here at Lost Valley while working to care for their dormitories.  Her favorite activities are engaging in the creative thought process that only alone-time can harbor and spending time in gratitude with her Vizsla, Zushi and/or the community at Lost Valley — all of which are integral in her relationship to life, socially, personally, and ecologically.

Dima Tsatskin,  HIVE Coordinator

Dima Tsatskin


Dima, was born in Odessa, Ukraine in June of 1983. Dima moved to Moldova when he was 6, then moved to Sarasota, FL when he was 11 years of age. After 20 years of enjoying Gulf Coast beaches, Dima started to crave mountains and forests, which brought him, along with his partner, Liz, and their two dogs, Zushi and Gandhi, to Oregon, where they were blessed with an opportunity to live in an intentional community which is situated within the Lost Valley Educational Center, where they are honored to be residents.

Dima had no idea what was waiting for him here, and after settling in for a few weeks, he was presented with an opportunity to serve the community by playing a role of a HIVE Coordinator, someone who is the head of community HIVE Program (Habitat Improvement Volunteer Education Program). Dima finds the HIVE program to be a progressive and evolutionary model for maintaining community cleanliness and well being. In this model, inhabitants pay a monthly maintenance fee, and instead of using the funds to hire someone from outside to perform certain tasks that would fulfill community needs (cleaning bathrooms, hosting game nights, facilitating work parties, trail maintenance, egg washing, community council, etc.) the inhabitants volunteer to perform these tasks themselves, for which they earn HIVE credit in the form of dollar points that potentially nullifies their monthly maintenance fee. Pretty genius! Dima enjoys spending most of his time in solitude or taking his canine pals on nature walks, though really values and appreciates the social aspect of the communal living. Dima strongly believes that intentional community is the model for future type of lifestyles that the rest of humanity will sooner or later find themselves in.

Randy Tullous at Langtang


Randy Tullous, Head of Infrastructure
(Maintenance Lead)

Randy is originally from Nebraska. After graduating from college he set out to pursue one of his lifelong dreams to explore the Rocky Mountains and the Pacific Northwest. He explored the Rockies for 8 years as a seasonal wildlife research technician tracking ungulates. For unknown reasons, he decided to transition over to a fisheries biologist on Alaskan commercial fishing boats in the Bering Sea. Realizing, in Alaska, he more than likely made the most harebrained decision in his life he ended up enjoying every single moment for 6 years and learned a lot about life, love, people and himself.

Randy comes to Lost Valley after much exploration and contemplation of the senses, the environment that surrounds us and what’s really important to him. He’s a jack-of-all-trades with specific interests in natural building and carpentry. He loves to travel, especially to Nepal. Randy’s personal interests are hiking, Tibetan yoga, meditation, growing mushrooms and kittens.
