The only organization I can think of is imom. I have no idea how you qualify or if they are still around. I think I remember something about them needing funding.
Kuhio is strongly involved with imom, I believe. She may have more info if you want to PM her.

I just typed imom in google and here is their website. Take a look and see if they can help in any way.

I hope Jenn can get help to get Wrangler his surgery.
