Eyal Rosenblum

Executive Director

An avid traveler with over ten years of experiential education development under his belt, Eyal found a home at OG after planning the inaugural Middle East program in 2008. From 2010 to 2012, Eyal served as OG’s Marketing Director where he more than doubled the number of program participants in less than two years. In 2012, Eyal took on the role of Executive Director and has been loving life ever since.

When Eyal isn’t pestering his staff with odd tidbits of arcane trivia, he’s busy working on other projects close to his heart. In 2011, he founded Heart-to-Heart, which brings 20 Jewish and Palestinian Israelis to the Canadian outdoors for a three-week coexistence seminar. Before that, Eyal was on the founding team for the Young Social Entrepreneurs of Canada, which became the first and largest organization in Canada to promote and support socially enterprising youth in achieving their goals. Eyal graduated from York University in 2010 cum laude, received a certificate in Non-Profit Management from the Schulich School of Business, and was awarded the Social Economy Scholarship Award for his contribution to the social economy.

Shannon Greer

Finance Director

Shannon’s love of travel was born after a post-high school summer spent backpacking through Canada. She’s since taken it across borders, volunteering with rescued jungle cats in Bolivia, trekking through the mountains of Peru, and traveling overland from Toronto to El Salvador. In late 2012, Shannon was completing an international development internship in Honduras, wondering what adventure could possibly come next when serendipity led her to her new family at OG! As Finance Director, Shannon spends a lot of time making spreadsheets, and only a little bit of time daydreaming about kittens.

Ben Sampson

Director of Program Design and Development

It didn’t take long for Ben to figure out that he suffered from an acute case of wanderlust. On one fateful afternoon, a short commute home from school turned into a multi-year Euro trip that eventually landed him in Latin America. After a brief stint as a freelance journalist, Ben was both incensed and inspired by what he saw and returned to school at the University of Toronto. Undertaking degrees in Latin American Studies and International Development while living out of a backpack in Argentina, Ghana, Guatemala, and Kenya taught Ben the value of experiential education and now after six years as a Program Leader and Special Projects Director in Guatemala, Ben continues to explore the world through the design and development of OG’s new and custom programs. When he’s not at his desk, you can find Ben scaling a wall or hitting a ball.

Lauren Chu

Communications Officer

Despite studying engineering, Lauren much prefers valleys and mountains over valves and mechanics. She has hiked thousands of kilometres around the world, once planted 7000 trees in a day, cycled the length of Vietnam from Hanoi to Ho Chi Minh City, and has been on a 500km hike through the Appalachian Wilderness. In the summer you can find her on canoe trips or hike & bike adventures; in the winter, playing shinny on outdoor rinks or flying down a mountain on a snowboard. Lauren is keen to marry a passion for education with a love of travel with OG!

Anna Cunningham

Marketing Manager

Anna grew up travelling and camping with her family and friends, kayaking down the Ottawa River, portaging through Algonquin, and exploring parts of Canada and Europe. Inspired by a friend’s trip, she travelled to Southeast Asia on a life-changing OG program back in 2012, and she’s been hooked ever since! In her spare time, she likes taking photos of pretty things and places, swimming, reading true crime until she can’t sleep, listening to endless podcasts, and watching bad TV.

Rebecca Tischart

Financial Support Coordinator

Rebecca has been super curious to learn about the world since the day she was brought into it. So far, her drive to explore hasn’t changed a bit! After a trip to Kenya she realized the best way for her to learn about and contribute to making our world a bit better by the time she leaves it, was to leave her corporate office job at a bank (womp, womp), and make a career shift to the non-profit sector! She quit, went to school, then spent some time living, working, and exploring in Bangladesh and Nepal. Finally back in Toronto, she’s very excited to help OG participants find their own life-changing experiences! When she’s not helping people reach their fundraising goals, Rebecca is probably running for miles outside, coaching her cheerleading team, or looking for some mountains to ski down.
