Flight school recommendations for private pilot certification

My dads dream is to get certified as a private pilot, and I want to find a reputable flight school for him. Looking for a program to fly a Cessna 172, not a commercial plane.

I’ve done some research and found 5 in the area. They seem to all offer the same services, training program and comparable cost. Want to see if anyone has had experience with any of these programs or received their certificate from the below. Thanks!

• American Flyers
• United Flight Systems
• The Flight School
• Texas Flight
• Aero HP
