After several years, Rabbi Aranov transitioned into the healthcare field, where he continues to work professionally. He later relocated to Chicago, where he remains deeply involved in Torah teaching and kiruv, offering shiurim and learning opportunities to a wide range of audiences.

Rabbi Aranov is currently active with Avodas Halev, a local Torah organization dedicated to strengthening avodah shebalev — authentic, heart-centered service of Hashem — within the Chicago community. Through shiurim, events, and educational programs, Avodas Halev seeks to ignite a deeper and more lasting connection to Torah and Avodah.
