I am unfamiliar with the providers in Irving, however if you are willing to drive to Bedford. My Pediatrician is wonderful. I was on cash pay for a little while and I felt that I received the same attention and care for my child as if I did have insurance. The office visits and shots were reduced, and he worked with me on appointment times because of my lack of insurance. My provider is part of the Cook Children's Physician Network, which is a wonderful group for Tarrant County. He name is James C. Wheeler, M.D. and phone number: ###-###-#### He does work by appointment only, and I have never had to wait more then 5 mins past my appointment time to be seen. The staff is very helpful and understanding. If immediate care is needed for your child they are willing to work you into their day, even if you call 5 mins before 5pm. They also have an after hours clinic for more emerg. cases, that is for walk in, however I have never used it.
