“Bringing together the skills of Dr. Weiss’ excellent pediatric medical care and Diane’s parenting guidance truly is every parents dream and a wonderfully unique approach to the delivery of pediatric care in our community.”

“From the moment Dr. Weiss visited Anna and I after delivery, I knew she was in the best hands. The staff was extraordinary, from Kerri’s friendly welcome, to nurses like Rosemary, who would even call me on her day off. If she didn’t know the answer, she would find it out for me. She provided invaluable guidance through my breastfeeding stage and her compassion and caring always put me at ease. Dr. Weiss’ extensive knowledge, wisdom, calm demeanor and sure-handed approach always put us at ease and made us feel lucky to have him as our pediatrician.”
