Narrative:

While at the FBO ramp we were given taxi instructions to runway 12 (lgb) via txwys B and D to cross runway 7L at taxiway D. This is what I read back. En route to runway 12 we did not turn at 45 degrees left to continue onto taxiway D then cross...but instead crossed runways 7L/25R and 12/30 at the taxiway B intersection. We were then asked by ATC of our intentions. Phone calls with the tower followed immediately prior to departure. Cause: PIC (me) head down running checklist (taxi/pre-departure) and not paying close attention to sic while taxiing. PIC complacency while operating with a very new crew member! Side note: before entering/crossing any runway, active or not, I always visually clear both ends (bases and finals) and have the sic do the same. It was done at lgb prior to crossing runways 7L/25R and 12/30. Solution: 100% situational awareness at all times and flight deck discipline! Supplemental information from acn 577993: cause: sic misinterp of the grouping of signs at the B and D intersection.
