Narrative:

We had been cleared for touch and go runway 25L straight in from 3 mi out. Slower traffic was landing runway 25R and about 1 mi final at 2 mi we were changed to runway 25R. Traffic ahead was touching down. Additional traffic was now on base for runway 25L. Traffic ahead was touching down runway 25R. Tower instruction was traffic ahead closed right traffic, cleared straight out after touch and go. Traffic ahead stopped on the runway then accelerated to takeoff. Due to traffic in the left pattern a go around to the left side was not possible. The traffic ahead was now starting a climbing right turn. We had at this point initiated our go around. We passed under the climbing small aircraft Y as he initiated a left turn back into the departure corridor of runway 25R. Tower advised when we cleared below the overhead traffic at 1800' MSL. The airport is 1475' MSL.
