How do I find part-time services for my dad?

Most in-home care agencies will work blocks of time. You just set up what you want. Look for an agency that is part of a well-known chain such as Home Instead or Comfort Keepers or a local agency that has a good reputation. Either way, ask for references. Your dad's needs shouldn't be hard to meet with an honest conversation with the agency or caregiver involved.
Good luck,

You can hire a caregiver through a local senior care agency.

Talk to me if your Dad lives in Sacramento, CA or surrounding areas.

Check your cities Area of Agency and Disabilities. They have all sorts of resources for the Elderly and Disabled. And it's a service that is based on income level of the elderly that needs it.

oops...I should have proof read before posting..thats *Area of Aging and Disabilities.

I agree with everyone that a in-home caregiver is what you need and you even got some good suggestions on where to find an agency. However, there's usually a 2-hour minimum.
