Pediatricians in Miller Place, NY

recognized patient-centered medical home NCQA badge

Personal Pediatrics is a small pediatric practice dedicated to the health of our patients from newborns through young adulthood. The practice was started over 40 years ago by Dr. Harvey Kolker. He was subsequently joined by doctors Jennifer & Lauren Byrne. The experience of our physicians, as well as their warmth and compassion, has kept families in our practice for years. Many of our parents started out as patients themselves and now continue to trust us with their own children. After Dr. Kolker's retirement in 2014, the sister pediatricians continued to create close relationships with all of the patients.

We take pride in the “Personal” of Personal Pediatrics & your name is remembered in our office. Our goal is to provide parents with encouragement, education, and support while providing excellent medical care for their children during illness and throughout their healthy development.

Having a small number of providers allows us to have excellent continuity of care. The doctors are always available by phone during the day no matter what questions you may have. A sick child will always be seen the same day as you call. Our office has both well & sick waiting rooms.

Our office is equipped with electronic medical records. We have access to your child's lab reports, radiology reports, and immunization records at our fingertips. Need a prescription? No waiting in line at the pharmacy with a sick child. We can send it electronically directly to the pharmacy.

We invite both expectant parents to schedule interviews with our doctors to learn more about the practice. Taking care of families and helping them as they grow is our privilege. We look forward to the day when our family will meet your family.

We love Personal Pediatrics! We have been patients since the kids were born. We have had wonderful experiences. Our favorite NP is Theresa. She is amazing! She is extremely kind, personal, caring, and very dedicated to her patients. Theresa takes the time to answer all questions, provide suggestions when needed, and does not rush through the visits. She makes the kids very comfortable and it is obvious she is passionate about providing the best care possible and loves what she does!

I have been bringing my 2 boys to personal pediatrics for a little over 6 years now. I absolutely LOVE Theresa and the Byrne sisters. They have always been so very patient, informative, caring and also give great advice. They are great with my boys. After my second son was born I suffered with some PP and I will always remember how supportive, patient and comforting Theresa was during a wonderful but difficult time.
