Companion Care Needed For My Mother In Reston

About who needs care: My mother recently lost her husband of 62 years. She is Japanese, English is her second language (but speaks pretty good English!) and has short term memory loss. She has never driven and my dad had been her primary everything. About the care needs: Very very patient person with experience working with seniors with memory loss. Kind, respectful (we are an Asian culture so respect and manners are important), and positive happy demeanor. My mom can walk (slowly and with a cane) and tries to do most things on her own (like heating up food, making tea, etc.). She also needs companionship - someone who will talk with her and ask her how she is doing. Services needed include: transportation for grocery shopping, hair and medical appointments, etc. Her friends also help with transportation but like some backup options.
