We use Dr. Frank Martinez in Allen and LOVE him. I'm not sure if he has privileges at Childrens but know that he does at Medical Center Plano and it is a fantastic hospital. He came highly recommended to us from our Neonatologist in the NICU after our twins were born at 28 weeks too. He is an old fashioned doctor, but stays current on new practices and medicines and is not concerned like some doctors about growing his practice so large that he cant manage it himself.
He has nurses but does not have a Nurse Practitioner so every time you take your kiddos in or if you have him paged after hours you see or talk to him. When one of my girls was 9 mo. she got the Rotavirus and almost had to be hospitalized. We spent the whole day in his office so that he could come in every 30 minutes and check on her. He has also called us one night about 10 pm to check on us after we had been in earlier that day and has kept the office open at lunch to see us the day after my newborn baby boy was discharged from the hospital and his jaundice got worse. His # is ###-###-####. I hope this helps and good luck.
