Bring the Lessons From the Edge of the Universe back down to Earth Ignite your Audience and Book Dave to Speak
"The universe didn't change me. It just reminded me what matters."
"I didn't set out to be an astronaut. I set out to make a difference.
As it turns out, the two aren't mutually exclusive."
Dr. Dave Williams — Astronaut, Physician, Author & Speaker
SPEAKING
What does it feel like to float 400 kilometres above Earth, or perform surgery on the ocean floor? Dave Williams doesn't just describe these experiences — he draws out the universal lessons buried inside them: how to lead under pressure, build teams that trust each other with their lives, and find clarity when the stakes couldn't be higher.
For almost two decades, Dave has brought these stories to boardrooms, conferences, and classrooms around the world — always with the same quiet conviction of someone who's seen the big picture, literally.
BOOKS
Dave writes the way he lives — with curiosity, honesty, and a genuine belief that every reader has more potential than they've yet discovered.
His adult books span space medicine, leadership, and the lessons only extreme environments can teach: Defying Limits, Leadership Moments From NASA, and Why Am I Taller? explore everything from astronaut physiology to high-stakes decision-making. He is also a featured contributor in How to Survive and Thrive Volume III, curated by Reebok founder Joe Foster.
For young readers, the award-winning Dr. Dave Astronaut series with Annick Press has been sparking a love of science one curious kid at a time.
CONSULTING
Few people have led teams through life-or-death decisions in an emergency room, on the International Space Station, and in a hospital system of 4,500 people. Dave Williams has done all three.
As former President & CEO of Southlake Regional Health Centre and current CEO of LEAP Biosystems — a Halifax-based company advancing space medicine and precision health — Dave brings a rare combination of frontline experience and executive leadership to every engagement.
He works with healthcare and aerospace organizations on the challenges that matter most: building high-reliability teams, leading through uncertainty, and creating the culture and systems that turn good intentions into exceptional outcomes.
ABOUT ASTRODAVEMD
Dave Williams didn't set out to become a record-holding astronaut. He set out to help people — a curious kid from Saskatchewan who became a neuroscientist, an emergency physician, an astronaut, then ended up floating 400 kilometres above Earth.
A veteran of two Space Shuttle missions, Dave has logged over 687 hours in space and holds the Canadian record for spacewalks — three EVAs totalling nearly 18 hours outside the International Space Station. In 2001, he became the first Canadian to have lived and worked in both space and the ocean, participating in NASA's NEEMO 1 mission inside the Aquarius undersea habitat. He later returned as Commander of NEEMO 9, leading an 18-day mission to advance remote medical care technologies for deep space exploration.
Beyond the missions, Dave has led at the highest levels of both aerospace and healthcare. As the first non-American Director of Space and Life Sciences at NASA, and later as President & CEO of Southlake Regional Health Centre, he spent decades applying the same high-reliability principles that keep astronauts alive to keeping patients safe. Today he serves as CEO of LEAP Biosystems, advancing the frontiers of space medicine and precision health.
He has been recognized with seven honorary degrees and is a Member of the Order of Canada, the Order of Ontario, and the Canadian Aviation Hall of Fame — honours he accepts with the same quiet gratitude of someone who still can't quite believe he got to do all of this.
