Marissa Dolotallas, Guide/Host

Marissa is a coastal soul with a corporate edge, blending over 25 years of business savvy with a passion for wild places and mindful living.

Raised in the seaside town of White Rock, BC, Marissa's love affair with nature and the ocean began early - whether hiking forest trails, dragon boat racing, or catching the wind on a sailboard. She later pressed pause on outdoor adventures to earn a business degree and dive into the fast-paced world of tech during the dot-com boom.

But the pull of salt air and soul-centered purpose was too strong to ignore. Trading suits and heels for board shorts and flip flops, she launched a second act that’s all about adventure, empowerment, and connection. Now based in Meaford, Ontario, Marissa is a certified sea kayaking and standup paddleboard instructor, retreat host, and founder of her own adventure company.

From leading backcountry kayak expeditions along Canada’s rugged coasts to guiding in Alaska, Greenland, Iceland, and Antarctica, Marissa brings heart and expertise to every journey. She’s also a proud leader at the Women on Water (WOW) paddling festival and curates Paddle/Hike/Yoga retreats designed to spark joy and personal transformation.

At home, she stays deeply involved in community life - organizing beach cleanups, hosting Yoga in the Park, maintaining trails, and served as Chair of Meaford’s first-ever Parks Advisory Committee.

Whether she’s navigating polar waters or local trails, Marissa leads with joy, courage, and a deep respect for nature.

Chris Scerri, Guide/Host

Chris splits his time between his two passions, music, and the outdoors. Hailing from the artistic community of Meaford, Ontario, just steps from the shores of Georgian Bay, there is no shortage of inspiration.

Chris has spent the better part of the last decade performing, producing, and promoting local live music. He has created concert series and show productions that bring together exceptional local talent.

When heʼs not on stage, you can find Chris exploring new trails or paddling on the water. Chris feels right at home in a kayak, canoe, or a Zodiac, and is a Paddle Canada certified instructor. Locally grown produce and creating delicious food is something Chris also loves. Like music, food tells us so much about those who create it and is another way to bring people together.

Being part of the Adventure Canada team gives Chris an opportunity to share his love for music and nature while exploring some of the most beautiful places on the planet!

For over thirty-seven years, he was Officer and Project Leader at the Geological Survey of Canada, leading field science expeditions to study unknown or little-known destinations and phenomena in remote parts of the world, from the Coppermine River area in the Canadian Arctic (where he and colleagues discovered the oldest rocks in the world) to Banks Island, the Keewatin, northern Quebec, essentially all of Baffin Island, western Greenland, northwest Scotland, the Himalaya of Pakistan, India and Nepal, and the Tibetan Plateau in China. His documented contributions to scientific exploration and geological field research are evidenced by the publication of over 135 peer-reviewed scientific papers in international journals, 120 geological maps (a record at the Geological Survey of Canada), and 150 conference abstracts.

He received the Geologic Mapping Award from the Geological Society of America and the Gold Medal from the Royal Canadian Geographical Society in 2016. He most recently received the Stefansson medal from The Explorers Club in 2023 and the Dave Elliot Award for the best paper in Tectonics from the Canadian Tectonics Group in 2024.
