Easton's reputation as a dialect coach extended beyond Hollywood sets and Broadway stages. Over the years, he was also hired by business executives, trial lawyers, religious leaders, university professors, and by others who sought to soften their accents or alter their speech in other ways to improve their communication skills or to increase their self-confidence when making public presentations. In addition to instructing actors and other clients individually, Easton shared his expertise with groups of students by teaching classes in the anatomy of language and the use of dialects at both the University of California, Los Angeles and the University of Southern California. Although Easton's work as a personal coach and classroom teacher occupied the vast majority of his time during the final decades of his life, he still found time to act periodically in films, on television series, in made-for-television movies, and to perform voice characterizations.
