We also went to N. Dallas Ped. for several years, but I was never really happy with them. We saw Dr. Droge (who has since moved away) in the Plano office, but also visited the Frisco office sometimes for sick apts. Whenever we went in for sick apt.'s we were seeing a different Doctor or many times just the nurse prationer. The office staff was not very friendly, and ususally when I called with questions for the nurse, I wouldn't get any good advice, she would just tell me to bring my child in. Dr. Droge also refused to give me a referral to a specialist when we suspected after many ear infections, terrible sore throats, and problems with sleep apnea,that my son may need to have his tonsils out. Even his Dentist commented that his tonsils were huge and looked like they might cause problems long term. I finally talked the nurse practioner into giving us a referal since our own Dr. would not, and my son did have his tonsils removed. We had other problems with their office and my Dr. in particular, I am very glad I left and don't know why I even stayed so long, i just wasn't sure who to go to.
We are very happy with our new pediatrician, and his nurse is so nice and full of good advice when you call her. We now go to Dr. Nail at Centennial Pediatrics, several of my friends go there and see Dr. Guetersloh, and just love him. The only problem is that they are only taking new babies, but since you are expecting, maybe they will take on your whole family.

Even if you don't end up going there, ask around, I think you can find a practice that you will be happier with than North Dallas Pediatrics. Good Luck!
