Letters of Rec Question

Hi All,

So I work at a PT clinic with several therapists and have already asked one for a letter of rec for applications this fall. For the programs that require a second therapist LOR, do you think it would be in my best interest to ask a therapist I have shadowed elsewhere for my second letter?

I think I would have a higher quality letter coming from my clinic, but I bet it would help my application to have one from somewhere else as well.
