Our Staff

A staff of professionals who have been touched by disability.

At CODSN we use a peer-delivery model, which means that each of our staff has in some way been touched by disability. On this page, you’ll connect with our wonderful team and learn about why they’re so passionate about serving people with disabilities, including those in their own families.

Stefany Cunningham

Lead Program Coordinator

Stefany was born and raised in Central Oregon where she graduated summa cum laude from OSU-Cascades. While she studied kinesiology, her love of learning guided her to explore
additional concentrations in psychology, and early childhood development and education. While exploring these concentrations, she expanded her knowledge in: Infant and child development; human lifespan development; family studies; families in poverty; family, school, and community
collaboration; positive psychology; and social psychology. After college, Stefany’s heart led her to work in early childhood education where she gained experience in caring for, and supporting, children and families with diverse support needs.

Stefany’s passion for life-long learning drives her to endlessly seek out continuing education courses and books concerning child development, self-regulation, autism and neurodiversity, augmentative and alternative communication, and supporting all children in becoming self-determined and life-long learners. At the heart of Stefany’s love for learning is her bright, funny, and courageous son, who is neurodivergent and has complex communication needs. Stefany values diversity, the voices of self-advocates within the disability community, and her life as a mom. Each day, she aims to learn something new that empowers her to provide her son – and all individuals with complex support needs – the support, care, and advocacy they deserve.

Nancy Stevens

Program Coordinator – Central Oregon

Nancy has been a life long self advocate with support from her parents, family, friends, coaches, and coworkers. From a young age, she learned the importance of inclusion and building self-confidence. Because of her parents’ optimism and strong committed belief in her abilities and their willingness to guide her in many outdoor activities, Nancy was the first blind woman to climb the Grand Teton. She is a 3 time world champion in the sport of Olympic Distance Triathlon and competed as a member of the US Disabled Cross Country Ski team in the Nagano Paralympics. When Nancy returned home from Nagano, she became a professional motivational speaker for diverse audiences. Her career as an Independent living skills trainer, Career Counselor, and Title 2 Claims Representative for people with disabilities, has been about assisting, advocating, and supporting people where they are at with services, guidance and resources. One of her passions is to empower individuals to pursue their endeavors and overcome obstacles. You will find her to be a tenacious, resilient, and creative motivator.
She encourages people to focus on commonalities instead of feeling nervous around people with disabilities. She was given great feedback from a high school student with a disability when he told her that after she had spoken at his high school, more students included him in class projects and extra curricular activities. As a person who is blind, Nancy has spent decades educating people on how to be more inclusive and relate to each other with dignity and respect. She is excited to be part of such a dynamic team at CODSN.

Grace Hardin

Program Coordinator

Grace Hardin has wanted to work in this community for a long time. In seventh grade, she completed a project illustrating what she wanted to do when she grew up and she said that I wanted to help people with autism.

Grace has a family member who has autism who introduced her to the world of disability. While in middle and high school, she volunteered as a peer mentor in the life skills programs. She then went to college at the University of Colorado, Colorado Springs, and graduated with a degree in Psychology. After graduating college, she worked with Head Start and enjoyed working with preschoolers. She noticed her tendency to get along really well with children experiencing disabilities and decided to find a job where that could be her focus. She became an Educational Assistant in a local high school Life Skills program and loved working with the students. That experience was life-changing and helped her identify how she could bring her knowledge of psychology and her passion for working with individuals experiencing a disability together.

Grace is now getting her Master’s Degree in Social Work and plans to go on to become a mental health therapist for individuals experiencing disability. Throughout her life, Grace has found that it is common for mental health issues in an individual experiencing a disability to be dismissed as simply a part of their disability and she believes that a person can have more than one thing going on at a time and that everyone deserves access to care.
