Does anyone have HoLEP experience with Dr Thomas Chi at UCSF?

I'm 73 with a 120cc prostate and urinary retention. I live in Colorado but I'm considering HoLEP surgery by Dr Thomas Chi at UCSF.  I've read most of the posts here, but haven't seen any mention of Dr Chi, nor any doctors in Colorado (e.g., Paul Maroni or Lauren Abrams). Does anyone on SteadyHealth have experience with Dr Chi or any doctors here in Colorado?
