Martha's Ranch Staff

Christy Radaker

Executive Director

After 26 years serving as a general education and special education teacher in the public school system, Christy joined Martha’s Ranch Foundation as the Executive Director in May 2023. Working with students having diverse learning needs, their families and leading teachers to fine-tune their craft are skills promoting equity, diversity and inclusion which parallels the core values of Martha’s Ranch Foundation. As the Executive Director, Christy continues her lifelong mission to empower individuals and families. She is committed to ensuring that every child, regardless of their background or abilities, has the opportunity to reach their full potential. Under her leadership, Martha’s Ranch Foundation is poised to make an even greater impact on the lives of those we serve.

Outside of her work with Martha’s Ranch Foundation, Christy enjoys spending time with her husband, Phil, and their blended family. Her son Zac is a Staff Sergeant with the U.S. Air Force, and her daughter Alyssa is pursuing her master’s degree in Kinesiology (Sports and Education Psychology). James and Nathan, twin bonus sons who are affected by autism, enjoy attending school, activities outside of school, and going on adventures with the family. She’s a lover of nature, gatherings of family and friends, planning events, and learning all she can to make a difference in the lives of herself, her family and others to make this world a better place. Christy’s dedication, passion, and leadership will lead Martha’s Ranch Foundation to achieve its mission by enriching the lives of others.

Kennady Wagner

Special Projects Manager

We are honored to have Kennady as our Special Projects Manager and leading our marketing communication. She has a remarkable track record of executing impactful initiatives and a passion for positive change. Kennady brings a wealth of experience to our team and holds a degree in Animal Science. Her deep commitment to the belief that every individual deserves the opportunity to thrive, Kennady’s drive to move our mission forward is unwavering. She believes whole-heartedly that Martha’s Ranch Foundation will make a long lasting impact on the families affected by autism.

When Kennady isn’t leading projects at Martha’s Ranch Foundation, she enjoys training Border Collies and spending time with her family. She’s also the proud owner of a successful online clothing business. We are extremely thankful Kennady made the move to Texas three years ago from San Diego, California. Kennady’s diverse experiences and interests enrich her contributions to our team and mission of Martha’s Ranch Foundation.

Braden Roach

Animal Manager

From an early age, Braden has been drawn to the world of animals so having him as our Animal Program Manager utilizes his profound love for animals and extensive experience in their care. Braden possesses a wealth of understanding and knowledge of the unique needs and sensitivities of different species and works diligently to care for the well-being of our animals. His work reflects this commitment, ensuring that our animal programs are not only enriching for the animals but also transformative for the individuals and families we serve.

Braden’s presence on the ranch seems to be 24 hours a day, seven days a week but he does enjoy watching baseball or college football with his son, Karter, and spending time with Kennady. Outside of his responsibilities at the ranch, he can often be found among the cows, training his Border Collies, or team roping. Braden’s strong alignment with Martha’s Ranch Foundation’s mission and values is evident in his viewing our animals as integral members of our community.
