Dr. Sirlin was recommened to me by my son's pediatrician when he stopped gaining any weight or height at 4 months. We were able to get in to see Dr. Sirlin in record time (4 days later), and our visit was very comprehensive. Dr. Sirlin spent about 40 minutes with us, recommened some tests, and we scheduled a follow up for one month later. A week after the appointment, I got a copy of the letter he sent to our pediatrician. It was remarkably thorough. He mentioned everything we had discussed, and the three pages also filled my husband in on everything that happened at the visit. I was very impressed with Dr. Sirlin's professionalism and personal attentiveness. He really listened to all that I had to say, had questions for me, and very complete answers for mine. I would truely recommend Dr. Sirlin to everyone - he is an OUTSTANDING MD.
