I can highly recommend Navajo Aviation. They are located in Concord, California; approximately 30 miles NE of SFO. Excellent maintenance (4 yrs flying and only ONCE had to "down" an aircraft on a tech), training environment, etc. Equipment consists of Piper Tomahawk,Warrior II (vfr & ifr),Archer and Beech Duchess (ifr)for multi. Good staff/instructors as well...got my ppl,cpl,me,ir there.
