Booker T was a licensed TD for a year a while back. The group I was with had to recertify dogs each year. He was always a calm boy so was perfect for it. We visited senior care homes. Most of the patients had had dogs growing up and would light up when they got to pet one.

We either licensed under TDI or Delta. I can't remember which. The group I was with disbanded, but there are a ton of them out there. I think you would really enjoy the smiles on the patients faces :)
