Drive Senior To Doc Appt In Katy

I need a senior care provider with experience to drive my mother, age 76 to a doctor's appointment on Tuesday, Nov 5 at 8:30 a.m. We live in Falcon Ranch. Knowledge of medical or hospitals is helpful. She has an echocardiogram procedure which lasts one hour and an EKG which takes 15 minutes. I would like the person to be caring, and come pick her up, drive her to the appointment, go in with her and stay in the waiting room through her appointment. Help her with whatever she needs. Make sure she gets both procedures and then drive her home. She is a very nice lady. Super sweet. She walks on her own just fine, but isn't super super strong.
