Our Team


Anne Spiess
Executive Director

Anne Spiess has spent her career in the government affairs arena representing elected officials, trade associations, and nonprofit organizations. Upon graduation from college, she began her career in the San Diego home office of Federal Senator Pete Wilson, R-California, where she assisted with constituent issues. Anne then went to work for Governor Michael Dukakis, D-Massachusetts, in his Washington, DC office. She handled constituent communications and assisted with monitoring higher education issues for the Governor on Capitol Hill.

Due to a job relocation of her husband a few years ago, Anne and her family now reside in Dewey, Arizona. Anne is a native of Phoenix, however, spent her early years in Kansas as well. She attended the University of Kansas, majoring in Journalism, and graduated with a B.A. in Psychology from the University of California, Santa Cruz. In a volunteer capacity, Anne has served as president of the Shawnee County Historical Society, Topeka, Kansas, and as vice-president of the Alzheimer’s Association, Topeka Kansas Chapter.  

Anne's family received tremendous support from the Alzheimer's Association during her dad's struggle with Alzheimer's disease. After his loss, she was asked to join the Alzheimer's Association, Topeka Chapter Board of Directors. She moved into a leadership role with the Board serving as vice president and helped the Topeka Chapter Board and staff raise money in the community for others who were coping with the disease. Her family also participated in the Memory Walk, an event held not only in Topeka, but also across the United States. As her term on the Board ended and due to her background in government relations, she was asked to represent and lobby on behalf of the Kansas Chapters of the Alzheimer's Association before the Kansas Legislature. While she has legislatively represented numerous clients over the years, it was so fulfilling to see the efforts of their chapter staff, donors, and tremendous volunteers make an impact on the Legislature. Especially during Alzheimer's Day at the Kansas Capitol, they increased awareness of the disease and the resources available to citizens across the state. Legislators were always thankful for those resources as they too were trying to help their constituents dealing with Alzheimer's. Her service to the Alzheimer's Association was important not only to assist citizens in the community, but also to help heal her own family. Her dad had helped so many people throughout his life, they knew he would have been proud of their efforts on his behalf to better the lives of others. 

Anne has enjoyed riding and owning horses over the years and has helped her son to win one of the Kansas Cowboy Challenges. Anne and her family -- husband Ed, son Nick and his family -- enjoy walking, hiking, and camping with their numerous adopted dogs.

ANNE CALLAHAN
Equine Specialist - Silver Saddle Instructor

Horses have been central in my life since I was nine years old, and I had the opportunity to begin riding at my uncle's farm in Washington state where I grew up. I was in 4-H for nine years. I have been in several horse organizations over the years riding with Back Country Horsemen of Washington in the Northern Cascades, Quarter horse events, and have spent the last 10 years studying and riding classical Dressage and 5 years on the board for Northern Arizona Chapter of Arizona Dressage Assoc. I have a variety of riding experience and training that spans over 45 years.

I volunteered with Horses with Heart’s therapeutic riding program after moving to the Prescott area for several seasons. It was a wonderful opportunity and rewarding  to witness the happiness and connection the participants made with the horses. Horses do have a special gift of being able to touch your heart. I truly love working with and training them, and I enjoy sharing my horse experience and helping others make those connections too.


TRUDY CHAPMAN-RADLEY
Certified Instructor (CTRI), HwH Board Member, CHA Member

A whirlwind in Western boots, Trudy became the first Executive Director of HwH in 1996, just three years after joining the group begun by Vickie Stuart. A certified PATH Instructor and CHA Member, she’s been a fixture in Arizona’s horse world since 1970, from 4-H programs to nationally-sanctioned barrel racing competitions.

Born in Akron, Ohio and an Arizona resident since 1965, Trudy initially wanted to be a school teacher. Life had other plans, though, and she took her love of both children and horses into the arenas of Horses with Heart. Trudy’s hands-on horsemanship education has come from legends like Pat Parelli, Monti Roberts, Ned Leigh Equine Natural training. The Murray Family Butch, Joy and  TY now living in Stephenville TX.  Adventure In Awareness Barbara Rector, now located in Tucson AZ.  Bonnie Lemaire my first Barrel Racing lesson.

Describing HwH as her “second family,” Trudy knows better than most how “the horse-rider relationship helps make dreams come true.” Sometimes it can be challenging to see past a rider’s disability and find their ability, she notes. Still, “No wheelchairs or walkers are needed when you’re on the back of a horse. My passion has been to serve the disability community and pay it forward with love and compassion. I’m so blessed!” And one more thing… “When our riders succeed in our arena, they will succeed in the arena of life.”
