Metropolitan Opera soprano Ana Maria Martinez described Dylan F. Thomas as “thinking out of the box in an intriguing and captivating way… an inspiring director and mentor, particularly for young artists.” Superstar baritone Quinn Kelsey, a favorite at the Lyric Opera of Chicago and the Metropolitan Opera, says that Thomas, “utilized his own intuitive twists on the storyline of certain pieces to give me as a singer a different perspective of my interpretation.” Kelsey says that Thomas' unique new production and staging concepts “… could prove quite useful in bringing more and more audiences back to the opera. Mr. Thomas’ insight just seems to me to be a very healthy way to reenergize opera productions.”

In June 2018, Mr. Thomas directed Pagliacci for Opera Fairbanks in Alaska, with Metropolitan Opera conductor Gregory Buchalter in the pit.
