Miller began playing the piano at age seven but quit after five or six months. At age ten he started lessons again, quickly realizing that he had both natural talent and a love for the piano. A year later Miller began to play symphonies and entered his first competition. That same year, at age 11, he soloed with the Utah Valley Symphony, performing Gershwin's Rhapsody in Blue. When he was only 13 Miller performed during the Utah Symphony’s annual “Salute to Youth” concert, and was then invited to participate in the Symphony’s 2005 play-drama performance of “Beethoven Alive!”
Miller was the music Sterling Scholar for Delta High School during the 2007-2008 school year. He released his first solo album at 16 and also teaches private lessons. He has also soloed with the Southwest Symphony and the American Fork Symphony. Miller has earned numerous competitive awards, including the first prize twice at the encore Keyboard Competition, second prize in the inaugural Snowy Range Piano Competition in Laramie, Wyoming, and many more.
On May 19, 2009 Miller opened for the Utah Symphony’s All-Star Evening at Abravanel Hall. This was his last major performance before leaving that June to serve a two-year LDS mission in Houston, Texas.
He returned to BYU after his mission, and jumped back into his musical studies, earning a Steinway Piano and first prize in the piano division at the 2013 Young Artist National Finals Competition of the Music Teachers National Association. This highly prestigious competition involves many sub-levels and Conlan competed as the finalist of the South West division at the National Finals.
