Interpreters/agencies near Scottsdale AZ

I will be attending a medical conference in Scottsdale Arizona next month. It will involve a lot of technical, complex medical terminology, given by physicians for physicians. Is anyone familiar with agencies in that area who can provide that level of expertise? I'm worried the organizers will go for price rather than quality, and need to make sure the interpreters are appropriate for the task.

Thanks for you help

Thanks, OceanBlue7. I found that too. Many of the links are broken and not much info on agencies, but I appreciate you looking.

Any "inside information" out there?
