Michael Bertolami offers a wide range of music therapy services to groups and individuals with special needs of all ages and abilities in the Boston area. He works at Perkins School for the Blind and is Ivan's music therapist so we can vouch for him - Michael is just great!
Check out his website if you're looking for private music therapy services at home. He explains what music therapy is and also discusses the possibility of co-treating with related service providers. Ivan, for example, has a speech therapy session with his music therapy once a week and it is really motivating for him!
