Staff and Board Members

Jaime Arnett

Executive Director

Jaime has extensive experience in nonprofit management, grant writing, and the private, and public sectors. Her nonprofit career began a decade ago with Habitat for Humanity, where she held every position from volunteer coordinator to assistant director, working in both Washington and Oregon states. In the private sector, Jaime was the Executive Administrator for the Boundary Fish Company in Blaine. She is passionate about governance and politics and is also a former Blaine City Council Member! In 2015, Jaime began grant writing for ANT to stay meaningfully connected to her community. She was drawn to ANT for our natural approach to mental and behavioral health services and, being an avid animal lover, was especially curious about the benefits of human-animal interactions. Jaime was the Director of Operations & Development prior to stepping in as the ED in 2020. She has a deep appreciation for ANT’s culture of compassion, the spirit of our animals, and the brilliance of our staff. Contact Jaime at

Haley Didier

Program Instructor, PATH Intl. Certified Riding Instructor

Haley’s love of horses from a young age propelled her to study Equine Sciences at Colorado State University, where she graduated in 2010. Since then she has worked on various ranches, farms, and animal facilities and has always had an interest in animal therapy. In 2017 Haley completed rigorous training to become a PATH Intl.

Upon moving to Bellingham in 2016, she was instantly drawn to ANT and enjoys the tender, respectful, and reciprocal relationships fostered between animals and humans. If you can’t find Haley in the barnyard, you can find her exploring the beautiful wilderness surrounding Bellingham, mountain biking with friends, playing in lakes & rivers, or setting her creativity free through her love of painting. Haley also has a passion for traveling in search of adventure and experiences that feed her sense of wonder. Email Haley at
