Where can I get a legit ESA letter in Phoenix?

[jakecarter]

I live in a non-pet-friendly apartment, and my doctor has said that I qualify for and could benefit from having a pet for my mental health. However, she's unwilling to write an ESA letter for me because many healthcare providers have recently been sued by landlords for allowing pets, especially dogs, which end up causing damage to the property. Does anyone know a legit healthcare provider in Phoenix City who can approve me for an ESA letter? Or maybe someone who has gone through the process and can share how they managed to get it? I know there are websites offering ESA letters, but I'm not sure how trustworthy they are.
