@Bernard Sanga I'm a physical therapist as well.

This year I had a tenant move in, acquire a cat shortly after move-in, then get a service animal letter from their therapist after I sent them a violation notice to remove the cat.

I was a physical therapist but lost the love in doing it because of my new love for real estate.

Before i could reply she sent another message "I can renew the emotional support animal (with a therapist)".I know I can not deny her the rental based on the ESA.

Traveling med techs, ultra sound techs, physical therapists, lab technicians, nurse practitioners, floating respiratory therapists, to mention a few, all fit in this category of medical staffers.

Borrower has a good credit score,  good income, funds to close, been employed as a Physical Therapist here in the US for 7 months.  

I  It's an animal that has been registered as an Emotional Support Animal (ESA) by a licensed therapist, psychologist, doctor, psychiatrist or any other licensed mental health professional. ...

I think at times landlord are relationship therapist too  

I started to get very tired of his problem and I am not his family therapist. 

I have been reading a lot about this and it seems that landlords can request documentation from a health professional like the persons primary care physician or their therapist, and not accept the online certificate.
