S. - Try Dr. Joseph Savona - his office is off Red Bug Lake Rd. right near the Oviedo Mall. He has practiced pediatrics for decades (in fact he was the pediatrician of one of my friends when she was a child and now she takes her children to see him). My son was born this past June and we had originally started with a different doctor, closer to our home. We had a terrible experience and so took the recommendation of several of our friends and switched to Dr. Savona, even though he is about a 20-minute drive from our home.
His nurses and staff are warm and experienced and he has been patient and thorough in all of his exams and discussions with us. You can schedule a new-patient interview with him ahead of time (this is usually scheduled on Saturday mornings), and then make your decision afterwards w/o having to actually switch first. His office is open on Saturday mornings for emergencies and he also makes hospital calls for all new babies, etc.
My husband and I have had to call his night-time service once due to what we thought was an emergency with our son. His service actually forwarded us to his home phone (it was 3:30am!) and he answered our questions and put us at ease all the while being very patient.
His office number is ###-###-####. Hope this helps!
