Andrew Horowitz, Pianist

Teacher, Accompanist, Performer


I have been teaching students in Northern Virginia to love music and play the piano with confidence since 2000. A desire to increase the professionalism and quality of my teaching led me to open my own independent teaching Studio in 2008. I wanted a space where dedicated teachers and interested students could do serious work but also have fun. A space where young beginners, advancing teens, and adults could all feel comfortable and at home. And, a place where all students and all teachers have the opportunity gather together for group classes and recitals. 

My goal in short is to take interested and eager students of all ages and to give them the skills that will allow them to make music, and to listen critically and thoughtfully, long after their formal lessons have ended.

Education: Bachelor of Music in piano performance, George Mason University. Mr. Horowitz also holds the designation Nationally Certified Teacher of Music (NCTM). Notable teachers: Joanne Haroutounian, Robert Wyatt, Andrew Degrado.

Olga Roberts, Pianist

Teacher, Composer, Accompanist       

Olga Roberts began her life in music at the age of six in her native Russia when her mother discovered she had perfect pitch and signed her up for an audition with the local music school. Despite the fact that she was younger than the required age, she was admitted and for the next nine years was immersed in an intensive program of music education which included four to five hours a week of studying different musical subjects, daily piano practice at home, and a variety of tests, exams, and performances.

After this preparatory education, Ms. Roberts matriculated at the Music College of Archangelsk, Russia, where she earned both undergraduate and Masters degrees with Honors in piano performance and pedagogy.

Ms. Roberts has over 30 years experience teaching piano, theory, and composition. She has composed and designed many different piano and theory supplementary materials which she has successfully implemented in her teaching. Her students have performed in countless recitals and events. Her former students have grown up to be professionals in many fields, including music!

Her teaching method is based on approaching each student individually. She believes it is important to recognize each child’s potential and to challenge it—but in the context of a nurturing and fun environment. The ultimate goal is providing each student with a solid musical education and foundation.
