Sandi Lien - Accompanist Extraordiaire

Sandi Lien has over 60 years of experience as an accompanist, starting with playing for church and choirs and individuals in grade school through high school.  She developed a passion for musical theatre and was involved in directing and assistant directing Community Theatre broadway musicals for 12 years. 

​She has accompanied many professional groups and individuals over the years, and while her children were in school, accompanied many musicals, jazz choirs, church choirs, contatas, etc.  She has recorded music with her son and daughter, who are also musicians.  Most recently this spring she was the accompanist for the South Bay Singers concert “Messiah”.
