Narrative:

After taking off from byron I monitored the local airport from frequency until climbing through 3000 ft then I called norcal approach to get a squawk code and traffic advisories up to the skydivers jump altitude of 13;000 ft. On the flight climbing out I was not informed of the traffic an aircraft crossing my path from left to right that I turned left to avoid and then back right as the aircraft went by. Then over the top of us from left to right another aircraft that I heard and saw after it went by. I saw it was red and white in color. I advised norcal approach that we had just missed 2 aircraft. I got very little help from them. Lack of ATC advising me of this traffic.
