A voice gym for singers, speakers & storytellers
Voice Jam
Train your voice. Build confidence. Sing and speak with freedom.
What is Voice Jam?
Voice Jam was born from something Anastasiia kept seeing in her studio: so many of her students were searching for their people — a community of singers the way pickleball players find their crew and turn into lifelong friends. She knew it was time to give singers that same experience.
The DMV is full of wonderful church choirs, and Voice Jam is something different — a workout for your voice focused on pop, soul, R&B, jazz, rock, musical theatre, gospel, and a cappella. Contemporary styles, with a big emphasis on healthy vocal technique and singing in harmony together.
Because singers are vocal athletes, Anastasiia teaches you to engage your whole body for stronger, healthier vocal production — building real skill alongside the joy of singing with others.

Opera Singer & Conductor | Voice Teacher & Mentor | Community Builder
"Every person deserves to find their voice."
Praised for her "luscious" sound by Opera News, Anastasiia brings together performance, teaching, and a deep love for helping students discover freedom and joy in their voices. She holds Bachelor's and Master's degrees from the Curtis Institute of Music in Philadelphia.
Mrs. Sidorova has appeared with Opera Philadelphia, Wolf Trap Opera, Opera Columbus, the Ravinia Festival in Chicago, the Verbier Festival in Switzerland, the Russian Chamber Art Society in Washington, D.C., and Opera Delaware. She has also performed at Carnegie Hall and Merkin Hall in New York City.
Currently, Mrs. Sidorova performs and teaches throughout the DMV area. She is on faculty at the International School of Music in Potomac, sings as a substitute at Washington National Cathedral, and is Music Director at Potomac Presbyterian Church in Potomac, Maryland.
Voice Jam was born from her belief that serious vocal development and joyful community can exist in the same room — and that the most powerful voices are the ones singing together.
She is a proud member of the National Association of Teachers of Singing (NATS), the world's largest professional association of voice teachers, and of the American Guild of Musical Artists (AGMA), the union for professional performers.

What People Are Saying
"The boys were both a little nervous to change teachers, but I have been so impressed with the quality and dedication in Ms Anastasia's lessons. She treats them as fellow musicians and challenges them without making it feel impossible — and I can already see ways their skills are progressing."
"I came in convinced I couldn't carry a tune. A few weeks in I was harmonizing with a room full of people, grinning the whole time. It changed how I feel about my own voice."
"My daughter was shy about singing. Now she belts out songs at home and talks about her singing friends all week. The confidence is incredible."
"It's the one hour a week I truly exhale. Serious technique, zero stuffiness, and the warmest community I've found."
