Our Faculty

Kimery Duda, Founder and Executive Director

Kimery’s base camp is Austin, Texas – but, she’ll be the first to tell you that her home is where her heart is – and, that is, in the field. Her passion for adventure was ignited in 1996 by an expedition set out to climb the highest peak in Mexico, Pico de Orizaba. She was taken under the wings of a Mexican family who exposed her to some of the most pristine cultural, historical, and natural sanctuaries throughout Mexico.

Since then, Kimery continues to create and provide opportunities which embrace the ethos of the expedition – through adventure and education in a sustainable way. Kimery has traveled, climbed, surfed, and skied extensively on an international scope. Since 1995, she has professionally guided students, adults, and families in Southeast Alaska, Hawaii, Mexico, Costa Rica, Nicaragua, and to local, state, and national parks in the United States. She has safeguarded over 1500 special events – including USAT; USARA; WFDF; and NICA sanctioned events. Whether on the water, single track mountain bike terrain, or open water swims, Kimery and her team has helped prevent injuries and save many lives in their community as a first response medical team. Kimery and the staff of The Expedition School look forward to sharing and exchanging their knowledge, skills, and wisdom with you in the field.

Bonnie Watson

Bonnie grew up in myriad places around the U.S. in a family of artists and outdoor enthusiasts. By 2005, her focus turned entirely to the intensive study of classical ballet at Milwaukee Ballet Academy, which led her to study contemporary dance and composition, receiving a BFA in 2014 from the University of Wisconsin, Milwaukee.

Kerstin Wiggins, SUP Instructor

An avid stand up paddler, Kerstin has been paddling the Texas waterways for over 5 years. A surfer at heart, she has surfed waves in Texas, California, Costa Rica, Mexico, the Caribbean and Central America. She infuses her love of SUP and surfing and her desire to connect with others in a meaningful way in each interaction she has with students on the water. She faithfully practices her pop ups and sees each new day as an opportunity to practice what surfing and Stand Up Paddling requires… a still mind, healthy body, strong inner core (inside & out), respect for Mother Nature and a sense of wonder and adventure.

When not on the water, Kerstin can be found with a camera in hand photographing the natural landscape, with a pen in hand jotting down bursts of inspiration or with headphones on listening to Led Zeppelin.

Kerstin fully subscribes to the philosophy that you can’t stop the waves, but you can learn SUP or Surf! And you’ll find no better teachers than the extraordinary staff of the Expedition School!
