ISW Faculty
Our Faculty
The people who make mastery learning happen.
Our faculty members are subject-matter specialists with a deep commitment to bringing out the best in every student.
Real-world expertise
A board-certified physician, a working actor, a dance-studio owner — teachers who have done the work and love to teach it.
Decades in the classroom
Several of our teachers bring 20 to 30+ years of teaching experience to ISW.
Small classes
A low student-to-teacher ratio means your child is known as an individual.
