Castellano's House of Music is a family business. The Castellanos have been in the music store business for 3 generations. Their first store was Bath Music in Bensonhurst, Brooklyn. Bath Music was opened in the 60's and was owned and operated by Marion and Philip Castellano. Affectionately known as "Mom & Pop," they served the New York musician's community for nearly 4 decades.

In the 80's, Mom & Pop's son, John Castellano, opened up his own music store, Guitar City, in Brooklyn. After moving to Staten Island, John moved his music store to Staten Island as well opening up the first House of Music on Richmond Ave, followed by the opening of House of Music II on Hylan Blvd.

John Castellano is not only a business owner, he is also a 4th generation professional musician.

On any given day you can walk into Castellano's House of Music, and see John playing guitar and trading licks with his customers.
