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 program involves 5 days focused on learning about and building connections in the environmental field, followed by 5 days focusing on leadership and personal development.

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


  • Connect, experience, and learn from local professionals focused on environmental science and sustainability. Understand their career requirements, pathways, and experiences.
  • Participate in field experiences about sustainable architecture and design, environmental education, regenerative agriculture, and habitat conservation.
  • Engage in hands-on outdoor leadership training and field science. 
  • Develop communication, interview, and public speaking skills.
  • Discover the power of storytelling and shared experiences.
  • Become part of an ever growing network of past apprentices, community leaders, and the ACES family!

Week One: Building Connections (Monday, June 20-Friday, June 24)

The focus of the first week is on learning about the wide variety of environmental careers. Apprentices will participate in experiences around the Roaring Fork Valley for first-hand exposure to careers and topics in sustainability, science and education. The apprentices will reflect on their experiences and develop a plan to further explore their chosen career pathways. This week will culminate with a short presentation of what the apprentices have learned.

Week Two: Reflecting on Pathways (Monday, June 27-Thursday, July 1)

The focus of the second week is leadership and personal growth. Apprentices will spend Monday planning a 4-day backpacking trip in the mountains around Aspen (Tuesday, June 28-Friday, July 1) with their ACES instructors. They will focus on developing their leadership skills through practice, readings, journal reflections, and goal setting. Upon completion of the program, participants will become part of the ever growing network of apprentices, community leaders, and the ACES family.
