'K' is for Kids is Kid-tested great since 1999. [Try some of the songs.] Bruce Has an MA in Psychology and has worked with children in a variety of settings as a therapist, student advisor, teacher, and volunteer. Along the way, he has written several original songs in English and Spanish. The majority of the original and traditional songs are best appreciated by pre-k to 3rd grade but a couple are hits among the more discerning tastes of the upper elementary school crowd.
