About Josh Morris

Joshua Morris is the director of Grand Dynamics International in Asia and founder and CEO of The Progression Group, a multicultural organization that works with students, educators, corporations, and athletes to fuel individual growth, create meaningful connections, and prepare for what’s next. An entrepreneur, leader and coach based in Thailand since 1999, Josh excels in connecting teams, communities, and cultures, a skill that enabled him to play a critical role as the lead international team coordinator in the Thai Cave Rescue in Mae Sai, Thailand in July 2018.

Josh has worked with businesses, NGOs and governments to identify and harness opportunities to build a more sustainable future through a combination of education, personal development, business strategy, cross-cultural communication, and community partnership. In addition to directing vision and strategy for his own company, Josh provides leadership training and development programming to businesses throughout Asia.

Bridging the gap between language and differing cultural perspectives, Josh’s work with executives is focused on creating high-performing teams by fostering meaningful connections through shared experiences.

An experienced rock climber, caver and expedition leader, Josh leveraged a love of the outdoors and a passion for personal growth, and transformed it into a movement that empowers individuals, protects the environment, connects the community, and supports local economies. His extensive experience has helped him bring a compassionate, client-focused approach to his work and leadership, and has given him the unique ability to empower others to go deeper, climb higher, and fuel their personal and professional development.

Just as progression is a steady movement to a more advanced state or place, Josh guides others in their journey toward a more conscious, successful and fulfilling future.

About Josh’s Thailand Cave Rescue Keynote Speech

For more than ten years, Josh has spoken at events of all sizes, for organizations from numerous industries. His humility, energy, and prowess as a storyteller enable him to connect with a room of ten people or a hall of several thousand. As a leader and coach, Josh helps audiences bring a mindful approach to high stress situations, empowering them to achieve impossible results. Weaving in the story of his experience from the Thai Cave Rescue, his training as an expedition leader and educator, and everyday examples from life and business, Josh engages and inspires audiences, connecting them to their highest potential, and delivering lessons and strategies to get there.

In July of 2018 the world was mesmerized by the story of the impossible rescue of 12 members of the Wild Board football team and their coach from a flooded cave. As the world watched, all 13 members of the team were safely evacuated from the cave to safety above ground. It was an improbable rescue that inspired billions around the world. Few know the inside story and intimate details of what it took to achieve this incredible feat. Not only did it require innovative methods and new approaches in cave diving, but diplomacy and deliberation with decision makers to even arrive at the decision to dive the boys out, something that had never before been attempted.

On the morning of July 06, Josh Morris found himself in a military briefing room discussing plans for diverting water away from the cave. Little did he know that 18 years of cave exploration, fluency in Thai and experience in the corporate and government sector were about to converge, placing him at the center of the rescue. Within a few hours, Josh became a critical part of the rescue, acting as the chief international coordinator and government liaison between the international divers, US Air Force Para-rescue Specialists (PJs) and senior level Thai authorities.

Applying his knowledge of the Thai language, caving experience and experience leading teams, Josh was able to assist decision makers in accessing key information and presenting the information in order to assist leaders in making critical decisions at a time of great uncertainty. In recognition of his role in the rescue, Josh received the award of Knight Commander 2nd Class from the King of Thailand.

Josh’s speeches highlight the challenges of bringing multiple groups of people from different cultures together to align around a unified goal. Highlighting points of chaos, strong leadership and team spirit, Josh speaks about what it takes to achieve success including:

  • Establishing a common goal
  • Working outside hierarchy and tradition in order to get things done more quickly and efficiently
  • Creating a sense of urgency in order to improve performance

With more than 20 years of experience living and working in Asia, Josh weaves the challenges faced during the cave rescue with natural connection to everyday life and work, highlighting the need for agile decision making, mindful leadership, building empathy among the team, and taking risks in order to innovate for the future. Josh has worked with and delivered speeches to multiple industries including Private Equity, Venture Capital, Insurance, Chemistry, and Education. He can easily customize his speeches around relevant topics for different audiences.

Charles D. Hodges, Lt Col, US Air Force, Commander, 26th Special Tactics Squadron
(In regards to the Thailand Cave Rescue Mission 2018)
“Josh’s cross-cultural communication skills, perspective, and insight were vital to our team’s success. Those skills, coupled with his discerning leadership style, allowed us to navigate some tough cultural intricacies. Without him our mission would have never gotten out of the planning stages.”

Emily Merlino, Program Operations, Smartly by Pedago
“Josh was generous enough to be the keynote speaker at Smartly Institute’s Singapore Conference in August of 2019, and we could not be more impressed. Josh is professional and a pleasure to work with, and his speech was the highlight of the conference. You can tell that he really puts time, effort, and thought into his speeches. Our conference attendees were unanimously impressed with the caliber of his speech. We would love to work with Josh again, and would not hesitate to strongly recommend him as a keynote speaker!”

Charles Motion, Executive Director, Aviation, Willis Towers Watson
“Josh Morris visited our offices in May of last year to deliver a fascinating presentation on the well-publicized and dramatic cave rescue of Thai school boys football team.  I had originally heard Josh speak at an event at Tanglin Trust School and was struck by his insight into this extraordinary event.  It was immediately apparent that important lessons in leadership, crisis management, communications and clarity of purpose lay at the heart of his story and I was keen for Josh to come and speak to colleagues and clients along the same themes.  Josh tailored his presentation cleverly to meet our target audience and we received a huge amount of very positive feedback from those lucky enough to attend.  The only part we would change would have been to allocate more time to enable the audience to ask all the questions they wanted to.”

Adrian Gonzalez, CEO North Asia, South Asia, Pacific, Insights Division, Kantar
“At Progression, Josh teaches real life experiential leadership skills and has become a mentor and source of inspiration that has seen a number of our participants elevated to country CEO level positions. I am hugely grateful to Josh for his contribution to leadership development at Kantar. He is a tremendous asset to our company and indeed to leadership generally.”
