I went to Mayo Phoenix earlier this year and was very happy with the care I received. I met with a urologist there who ordered a reading of my MRI (done elsewhere) by their radiologist. Based on their radiologist reading of my MRI they then decided a Fusion MRI biopsy was warranted, which they then performed about 6 weeks later. I had the Fusion MRI biopsy through the perineum with general anesthesia and 2 anal biopsies 25 years ago while awake. No comparison. The Fusion MRI biopsy gives you confidence they actually sample the areas of concern and being under anesthesia was way better than being awake for the anal biopsy. I believe UCSF and Stanford are also first rate institutions, so I'd be happy to go to any of those 3. With the holidays I kind of doubt you'll get in anywhere much before 3/4 unless they just happen to have a cancellation, but it never hurts to try. Best wishes.
