Hands-on Care Needed For My Father In Pittsburgh

About who needs care: My dad is 88 years old and has dementia and physical limitations. My 85-year-old mother cares for him full-time, but needs help getting him showered and possibly helping him with his physical therapy exercises. About the care needs: My parents are very resistant to change and have been resistant to getting help. My mother is very private and proud. My dad is super stubborn but incapable of making decisions for himself right now. They would need someone who they could trust, who is gentle and kind, but also able to physically help my dad who may need assistance being lifted from a chair to standing. Services needed include: feeding, and bathing / dressing.
