I just finished a sunset hike with Jason this morning and I highly recommend him to anyone that is considering taking on the mountain. Jason made sure I was comfortable the entire time even as I struggled with my fear of heights a bit. He made sure I did not give up and made it to the top. I'm so glad he did because the views were absolutely worth it.
As for the mountain itself, it was challenging but definitely doable, especially if you have previous hiking experience. It's a must do if you are staying in the Phoenix area. I'd recommend getting there early like we did to avoid the crowds and the heat.
If I'm fortunate enough to visit Arizona again, I will without a doubt be booking another hike!
