premises at 5400 Hollywood Boulevard at Serrano Avenue with a recital on November 17, 1925. Opera singer Alma Stetzler taught singing at the school in the late 1920s. German concert pianist and composer Georg Liebling was a member of the piano faculty in the early 1930s. The school presented numerous student recitals and productions during the 1920s and early 1930s, as well as hosting concerts given by established professionals. During the late 1930s and early 1940s the conservatory portion of school reduced steadily. In 1929 Viola Foss Lawler established the Hollywood Professional School (HPS) at 5402 Hollywood Boulevard as a private school addition to the HCMA. This allowed students at the conservatory to attend grammar school and secondary school classes while studying subjects like music and drama. Lawler's school focused on catering to children in the entertainment business, following a similar model pioneered by the Professional Children's School in New York City. By 1930 there were close to 300 students enrolled in the first through 12th grades at HPS. Lawler parted ways with the HCMA in 1937 to establish her own independent school, the Lawler Professional School which was later known as the Mar-Ken School. The HPS continued to operate at the HCMA under Littell. In 1944 Littell sold the HCMA to Bertha Keller Mann and it ceased teaching the arts. The HPS private school became the sole focus of the institution. In 1948 the school was enrolling students K-12 and operating under the name the Hollywood Professional School while legally still existing under its former name, the Hollywood Conservatory of Music and Arts, on paper. Many of the pupils who attended the school were children working in show business, operating mornings only so that the children could work in the afternoon. It closed down in June 1985 due to insufficient enrollment and the death of the owner that same year. The school's building and many of its assets were auctioned in August 1985.
