Let the Cello Adventure Begin

About Me  

Hi, I’m Warren — a Chicago-based cellist and dedicated teacher who loves helping students grow. I have performed across the United States and collaborated with artists such as Leonard Slatkin. My playing has been featured on Classic FM, and I appeared on America’s Got Talent (Season 16).

 

For over a decade, I’ve taught students of all ages, helping beginners gain confidence and guiding advanced players to successful auditions and youth orchestras. My teaching blends clear technique, musical expression, and supportive mentorship.

 

My approach is rooted in the traditions of Ivan Galamian and Samuel Applebaum. I focus on building strong fundamentals while encouraging independence, creativity, and a love for music.

Testimonials

"My daughter has been studying cello with Mr. Oja for over a year and a half, and our experience has been wonderful. He is an extremely professional cellist, and his passion and sense of humor make every lesson enjoyable and productive. 
​
He is kind and genuinely cares about his students, especially when my child has difficulty understanding the music. We all love having him as our cello teacher and highly recommend him."
