I've been to Desert Valley Radiology two or maybe even three times, and always get the same great service. In and out, regardless of how busy they are, and whether I've made an appointment or not. I would say that Tuesday/Wednesday early morning seems to be pretty slow, so that's handy. The front desk folks and super friendly, as well as patient and informed. Paperwork doesn't take too long.
The radiology technicians are wonderful and respectful, gentle and patient. I will probably always use this business if I need to have radiology work done.
