Our Teachers

Our teachers come from all sorts of backgrounds, but they are united by a common passion: Sharing the joy of music with children and families. 

All While They're Little teachers have successfully completed the Music Together® teacher training, which is built on research in early childhood and music development. In addition, all teachers apprentice for at least one session with another experienced teacher. We keep our skills fresh through workshops every session and advanced trainings offered by Music Together Worldwide.

Judy Hausman Leff is the Director/Owner of While They're Little, a company she started after her second child was born. Her vision is to offer services and products to families with young children that will empower and nurture both parent and child. She is very proud to offer Music Together classes and loves that her job responsibilities include singing and dancing with your children! She has been studying voice since she can remember, taking a 12-year break from it to pursue a career as an actuary/risk management consultant. Music came back into her life after her children were born. Soon after, she was taking Music Together classes with them and was hooked! Judy has been teaching Music Together classes since 2003. In April 2005, she was awarded Music Together Certification Level 1 from the Center for Music and Young Children in Princeton, NJ, having demonstrated outstanding achievement in teaching, musicianship, program philosophy and parent education, and in August 2010, she was awarded Music Together Certification Level 2 for demonstrating mastery of those areas. Judy is proud to have had the first US Music Together center (and the only in NY) to offer a class in Hebrew as well as having been the only center on Long Island to have been chosen to participate in Music Together's Big Kids pilot in 2010, the Babies Pilot in 2012 and, most currently, Phase 2 of the Rhythm Kids Pilot in 2016.

Jenny Arrigo is an experienced vocalist who has always drawn inspiration from making music with her family. Since becoming a mom, Jenny has relished sharing music with her two young sons, and Music Together has been a wonderful catalyst for the family’s musical adventures. She is thrilled to join the teaching team of While They’re Little to help spread the fun of family music with others. Jenny performs regularly alongside her brother, singer-songwriter Alex Rubin. With his band and together as a duo, they have taken the stage at a long list of NYC rock clubs. They can also be found singing together any time they hear a Beatles song, or if they happen to be in the car at the same time.  In a unique family music endeavor, Jenny helped develop and produce a weekly jazz vocal performance and jam session with her dad, jazz guitarist Saul Rubin. The event ran weekly for over 5 years, during which time, she developed a repertoire and booked gigs as a jazz singer. Jenny recently reunited with her college a cappella group, the Harper Harpeggios, to benefit the Cystic Fibrosis Foundation. She has studied piano, and performed in several school and community musical theatre productions. She is currently working on her ukulele skills.

Katie Mitchell-Condon is thrilled to be joining the While They're Little family and is very pleased to combine two of her greatest loves, music and working with children. When her son, Robbie, was born, she took a break from working full time in retail to focus on being a mom, and that is when she discovered Music Together classes. Katie has had a variety of musical experiences from musical theatre productions in high school and college, to interning at a record label, and singing in her own rock band. She is currently recording an album, and playing shows with her band around New York.

Carole Hausman is not one of our teachers but is an important part of our team, having come out of retirement from Macy's to work in our managing office. She is very familiar with the Music Together program and philosophy, having taken the training in 2005. She is thrilled to be working closely with her daughter (she is Miss Judy's mom). In her spare time, Carole can be found spoiling her grandchildren.

Sadly, Miss Carole passed away in January 2017 but she still impacts the lives of children through our Carole B Hausman Memorial Scholarship Fund, which was set up to help families in need of tuition assistance.


  To Be Determined

Sometimes we just don't know right away who is going to be teaching a class. Rest assured we work hard to get you that information as soon as possible!
