Companion Care Needed For My Mother In Portland

I'm looking for companion care for my mother in her 90s. Medication management is required. Someone who will partner with her to do her exercises and/or talk an accompanied walk. Possible assistance in completing some tasks--simple things mom used to easily do, but a recent stroke has impacted her short term memory and it's hard for her to focus and learn or relearn how to--use her phone, watch a show, organize some drawers. We're looking for some help preparing a simple meal. Preferences for a caregiver who is a non-smoker, comfortable with pets and CPR / first-aid trained.
