We analyze the phi meson production in e(+)e(-) -> omega pi(0) as a probe for studying the isospin violation mechanisms. By clarifying the dynamic sources causing the isospin violation, we succeed in quantifying those mechanisms with the help of the recent KLOE data. Hence, the phi -> omega pi(0) we branching ratio is extracted. We find that apart from the electromagnetic (EM) transitions, the strong transition via intermediate kaon loops plays an important role in understanding the cross section and its lineshape.
