Trook Apprenticeship in Education & Environmental Careers

Are you interested in making lasting change as an environmental leader in the field of sustainability or education? Drawing on the incredibly strong network of Roaring Fork Valley businesses, organizations, and individuals focused on sustainability and the environment, the Trook Apprenticeship exposes high school students to the wide range of career opportunities as they develop into the environmental leaders of tomorrow. This 10-day program will take place June 21-June 25 and June 28-July 2, and is geared towards students entering grades 11, 12, or recent high school graduates.

This program is inspired by and in memory of former ACES Education Director Arin Trook.


  • Connect with local professionals focused on environmental science and sustainability. Learn about the requirements of their careers, experience needed, challenges, etc.
  • Participate in field study experiences in sustainable architecture and design, environmental education, regenerative agriculture, alternative energy, habitat conservation, and restoration ecology.
  • Participate in hands-on outdoor leadership training and field science. Develop your communication, interview, and public speaking skills.
  • Discover the power of storytelling and shared experiences.
  • Become part of an ever growing network of previous apprentices, community leaders, and the ACES family!

Week One: Field Study Week (Monday, June 21-Friday, June 25)

During the first week, apprentices will participate in field experiences around the Roaring Fork Valley to get first-hand exposure to careers and topics in sustainability science and education. The apprentice will develop an individual research plan to delve into a chosen career. This week will culminate with an overnight camping trip on Thursday night (6/24). 

Week Two: Career Study (Monday, June 28-Thursday, July 2)

The focus of the second week is hands-on experience with the apprentice’s chosen environmental career, along with field experiences with the entire group, readings, journal reflections, and goal setting. Apprentices will shadow and interview local professionals, and receive hands-on mentorship from the ACES Education Director, ACES Community Programs Senior Manager, and ACES School Programs Manager, and have the opportunity to present their research and experience at ACES. Upon completion of the program, the apprentice will become part of the ever growing network of apprentices, community leaders, and the ACES family.
