Narrative:

Tower was issuing departures off parallel runways 28L & 28R. Training single engine aircraft were departing runway 28R with a right traffic pattern. We were cleared to takeoff with instructions to fly the runway heading from runway 28L. A piper single engine was cleared for takeoff just before us on the parallel runway. He drifted in front of us as we were lifting off. We had to deviate from runway heading to go around the piper as we climbed above that aircraft.
