Meet Our Crew

This is OGHQ

From journalists to artists, accountants to mountain trekkers, our crew is unified by our love for experiencing everything this world has to offer. Together we’ve covered continents, reached epic peaks and lived far off the grid. We’re here to help you experience the world the OG way.

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.

Claire Ferguson

Programs Director

Claire grew up travelling. From riding horses in the Egyptian desert at age 9 to sailing between Indonesian islands at 12, being on the road was the only way to roll! She’s lived in a mountain village in Costa Rica, camped her way across Europe, went scuba diving in Thailand, and has spent a lifetime of moments getting lost in the chaos of India. She believes in the power of travel to expand us, to humble us, to change us forever – and wants to spread that passion with a world wide community of ethical backpackers! Working now for OG in Toronto, Claire can be found riding her bike in all sorts of bad weather, talking to strangers on the bus, or trying to do either of those things while soaking up her latest fave podcast.

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.

Justine Abigail Yu

Communications & Marketing Director

She’s that person. Justine’s constantly on her phone tweeting, Facebooking, or Instagramming like it’s her job (cuz it is!) She’s always excited to show the world all the incredible work the OG community is involved in. She’s been working as a communications strategist for non-profits since 2009 and has worked with organizations operating in North America, Africa, and Southeast Asia. She’s also a freelance writer whose work has been found in the African Business Journal, Makeshift Magazine, and Metro News Canada. When she’s not working or traveling, you’ll find her on the dancefloor, perfecting a sun salutation, or climbing rocks.

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.

Eric Schreiber

Community Outreach Coordinator

Originally hailing from Washington, D.C., Eric joined the OG team for a month back in 2013 and never really left.  His dusty old backpack has taken him across quite a few countries and even one continent.  Now he’s settled in Toronto, where he helps OGHQ put its best face forward.  If you can find him outside the office, he’s likely in the kitchen, fixing (breaking) his bike, or working on that handstand. He’ll get it one day.

Will Clarke

Financial Support Coordinator

Will started his journey at OG with a trip to West Africa in 2014, and hasn’t looked back since. After discovering his passion for travel and helping others, he decided that a career in the non-profit sector was right for him. Will is super excited to start his career at OG and see what this new adventure will bring. When not at the office, Will can be found with his nose in a good book or perfecting his personal best time for a 10K!

Anna Cunningham

Marketing and Communications Assistant

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 with OG back in 2012! Before OG she had been working in events and marketing primarily within the beer industry. In her spare time, she likes taking photos of pretty things and places, swimming, watching bad TV, and sometimes pursuing a certificate in Interior Design for no particular reason.

Allyson Fuller

Alumni Coordinator

Otherwise known as ‘Awkward Ally’, this small-town girl grew up dreaming of helping others and making a positive impact on the world. But first, she had to learn how! After finishing her degree in science, she decided it was finally time to travel and had the opportunity to join the Peru: Mind and Body program with OG. Upon coming home, she was inspired to help others experience volunteer travel by offering fundraising assistance and leading volunteer trips in Ecuador. Allyson now enjoys living and working on a hobby farm, helping her father sell lumber, and working as OG’s Alumni Coordinator to help backpacktivists keep their own momentum going!

Vivian Cho

Administrative Assistant

From navigating boulevards in Montreal to riding cable cars in Medellín, Vivian finds nothing more exciting than carrying a backpack through unknown roads and kingdoms. She is always prepared for an adventure, and considers getting lost in a new city an absolute necessity. As the newest member of OGHQ, Vivian helps in all things details, paperwork, and admin. After office hours, she can be found reading horror novels, brewing kombucha, or training for the next Ragnar Relay Race.
