Diana Horner

Co-Founder · Program Developer · Masterclass Coach

Diana Horner has spent 35+ years in the entertainment industry — starting as a model and actress herself before becoming a coach, talent agent, and manager. She's also worked in casting and directed and produced short films. She developed the training method behind National Performers Academy in 1977 and still actively coaches today.


What brought her back was training. Enrolling in a local modeling and acting school gave her structure, skills, and a place where her confidence could be rebuilt one step at a time. She never forgot what it felt like to be on the outside looking in, and that is still the heart of how she teaches.

Her own career took off quickly. She modeled on the runway and in local, regional, and national print campaigns. She became a sought-after fashion show commentator and producer for Seventeen, Mademoiselle, and Brides magazine shows, as well as the Edith Head Costume Show. As an actor she started in theater and the Thespian Society, then went on to national commercials, film and television roles, and extensive voice-over work.

In 1977 she began coaching. For the next 30 years, across two states, she also worked as a talent agent and co-manager. When casting directors needed a hard-to-find type, she was the agent they called first. She did all of this while raising her own family.

That experience on both sides of the casting table became the training system National Performers Academy uses today. Diana has coached actors, models, on-camera personalities, attorneys, elected officials, and corporate teams. She has received multiple Educational Excellence Awards and two International Lifetime Achievement Awards. She is a graduate of United Way’s Blueprint for Leadership and has served on numerous nonprofit boards.

Every NPA student meets Diana in the bonus masterclass at the start of Acting 101, and she coaches again in the advanced levels.


Diana knew she wanted to perform before she could explain why. She performed for family, for friends, and for an audience of one in the mirror. Then her family moved often, she changed schools again and again, and she became the target of bullies. The girl who used to perform for anyone became shy, withdrawn, and unsure of herself.
