I'm glad things are improving for Larry. That must be a huge relief for you, too!
If you ever find an RO with a bubbly personality, let me know. Between them and neurologists, there's not a lot of touchy-feely going on, in my world at least. I prefer the smartest available because the things they do and know keep me alive.
I've also found a good SLP understands swallow even better than most ENT's and nurse. That's all they do. I also had silent aspiration and even now, saliva and mucus runs unabated into my lungs. I don't choke at all as it happened over time and the body adjusts. I hack up food particles for hours after meals and have had pneumonia off and on for a couple of years.
If you challenge the knowledge of one provider to another, you may not get the care that is needed. Trust they know what they are doing. If you can't trust them, you have the wrong doctors and nurses.
Best wishes for continued good news and healing for Larry.
