Darci Jones is a licensed clinical social worker who has more than 20 years of clinical experience, specializing in trauma and nearly ten years of running a private practice. She was an Amiga many moons ago in Ecuador (1992) and then a Route Leader in Michoacán, Mexico. Most recently her teenage daughter has been an Amiga for two summers. Darci is thrilled to return to AMIGOS in the capacity of Mental Health Consultant. She is excited about this opportunity and grateful for all of the dedicated intentional mental health work that has occurred within AMIGOS.

Darci specializes in working with couples and individuals. Her work has been in a variety of settings ranging from wilderness therapy, comprehensive school and community treatment, private practice to advocacy work through changing and creating policies. She is passionate in her client centered approach and weaving neuroscience within the work. The concept of mind body connection has been a guiding principle that she has consistently worked within.

Darci lives in Polson, MT with her husband and daughter. In addition to running a private practice she and her husband operate an organic farm. These two mediums assist her to find balance and farming provides her with the opportunity for introspection and assists her to release at the body level. Darci is thrilled to be able to have the opportunity to work with AMIGOS.

Hi everyone! I’m Grace, originally from Portland, Oregon. I moved to Lancaster, Pennsylvania in 2018 to attend Franklin & Marshall College, where I earned a B.A. in Environmental Studies and a minor in Spanish.

During high school, I participated in cultural exchanges to León, Nicaragua and Mexico City, which sparked my love for travel, cross-cultural connection, and learning from diverse perspectives. I’m thrilled to be joining AMIGOS as a Health and Safety Coordinator, and I’m looking forward to supporting students and families as volunteers begin their own transformative journeys abroad.

Outside of work, I love reading, crocheting, spending time with friends, and exploring new coffee shops.

I am from Quito, Ecuador, and I have been passionately working with NGOs for seven years. Before joining AMIGOS, I worked as the coordinator of a community center in a development organization, where I closely collaborated with individuals in vulnerable situations. My journey with AMIGOS started in 2022 as a Gap Coordinator in Cuenca, and since then, I have taken on various roles within the organization, contributing to meaningful youth development projects. Through AMIGOS, I have witnessed firsthand how young people open their eyes and hearts to growth experiences that shape their lives.

I hold a master’s degree in International Cooperation with a specialization in project management and a certification in Nonprofit Management. I am also passionate about traveling and hiking.
