Oh yes, that's Sabina with Serve Us Canines (in PA). If you want, I'll get her phone number for you.
Poodles make fabulous assistance dogs, and I ought to know because my Maddy assists me in many ways. My thumb joints are pretty much shot (bone-on-bone), but haven't had the joint replacement surgery because of the recovery time - I live alone, and just WHO could get groceries, do laundry, etc. Anyway, Maddy unzips clothing when necessary, pulls my jeans off, brings me whatever I ask for, helps me get up when I can't, brings in groceries from the car, puts many away, and much more. If only she could open bottles and do hair, I'd have it made! LOL
I trained her myself, and she pretty much showed Beau what and how to do things. They're wonderful, and I don't know what I'd do without them! When I fell and broke my leg and ankle in my back yard, Beau pulled me into the house and Maddy brought me the phone, so I could call for help. None of my neighbors heard me calling for help. Once home from the hospital, I needed their help a lot. My physical therapist was only 5.5 blocks from my house, so I used the (manual) wheelchair to get there and back, and Maddy came along, to help me up steep inclines, and eventually to keep me steady on my feet! Later, once recovered, I helped patients who used that facility to teach their pet dogs to help them at home. I'm working with the pet dog of an elderly woman who has mobility issues, and is a diabetic. Mac helps her get up from the chair, brings her cane to her, and we're teaching him to get ready-made containers of juice from the fridge, in addition to her insulin pack, and bring to her. Mac isn't suitable for public access, but he sure is helpful in the home!
There are trainers out there who would be capable of task training a Poodle for your dad. I'm no trainer, yet I was able to train the Poodles. Really, it's just a matter of good socialization, obedience training, and then task training. Poodles are awesome!
