Dr. Kelly did my surgery back in December. As I've said elsewhere, I thought that he and the nursing staff were very good. ALM was, in my experience, not good.
First, their driver was really disorganized--his sister ended up picking me up from the airport, taking me to her house, then finally after 2 hours, taking me to the hotel in TJ, all because he couldn't get across the border into the US. Then he got his brother to take me back to the US afterward. Very unprofessional.
I also thought that their new "patient advocate" was a complete joke--she barely spent 5 minutes with me the entire time I was there. The two times that I called her from the hotel with questions, she rushed to get me off the phone.
Then there was the "nutritionist." She delivered her prepared speech with poor English, was obnoxiously patronizing, and the post-op diet she gave me was VERY wrong--I double-checked it with Dr. Kelly, and he said I should totally disregard it and use the one he gave me.
So, all that is just to say that I had a great experience w/ Dr. Kelly, a bad one with ALM. Of course, everyone's experience is different, and I don't claim that Dr. Kelly is perfect. Just my $0.02.
