No, but I was under Bay who was just before Washburn. I was there from '85 - '87. I served in all leadership positions in the mission (for what it is worth). Washburn was from Page, I believe...I never got to that part of the mission.
I am still close and friends with one companion (we were ZL's together for 5 months). He is down to earth and has been a great friend for almost 30 years.
Two of my buddies from AZ PHX Mission are complete ex-mo's. Both were "pillars" in the mission and leaders. One now is a physician and the other is a business leader. Both exited the church in grand fashion. I'm sure there are a lot more that faded away or just quit going.
