Toward the end of Fifteen, Ott released the 1998 solo acoustic album, Epithysial Union, which also featured songs by Amanda Ketchum (billed only as "Amanda'"). In 2000 Ott sold everything he had to buy a house and support his children. He pursued a solo career for several years, releasing the double album, Will Work for Diapers in 2003. In 2003 he entered nursing school and went on to train as a nurse practitioner. In 2007 he stopped recording music in order to devote more time to his studies. In December 2011 his band Fifteen reunited to play two Bay Area benefit shows. He now is a nurse and is helping drug addicts.
