Why families choose Uptown Pediatrics
Concierge-level care, with the insurance you already have.
Families who join us from other practices often notice the difference right away. We’re an independent practice, not a hospital or corporate chain, so we can offer the kind of personal care that’s increasingly hard to find: quick responses, easy access to your pediatrician, and a team that truly knows your child and family. We believe exceptional, personalized care should be accessible to everyone, and we accept a wide range of insurance plans.
Independent & physician-owned
No hospital system or corporation owns us. Our doctors run the practice, so decisions about your child's care are made by the people who know your child.
You'll know your doctor
You see the same doctor at every checkup, and most sick visits too. We know your kids well, and they know us.
Here when you need us
Portal messages answered throughout the day, one of our own doctors on call 24/7, walk-in and Saturday sick visits. We never turn away our patients: if the schedule is full, we make room.
Specialists under one roof
Adolescent medicine, endocrinology, infectious disease, and psychiatry down the hall from your pediatrician. Easy coordination, no months-long waits.
Support for new parents
Prenatal visits, Mount Sinai nursery rounds, in-office lactation help from Nurse Mesi, and postpartum mood screening with a psychiatrist on our team.
A kid-friendly office
Our staff love kids as much as our doctors do. Some of our medical assistants have been with us for decades, and they know your children by name.
A practice that feels like family
When your child walks in, our team knows them and makes them feel at home. If you call in the middle of the night, you speak with one of our own doctors, not a nurse at a far-away call center. Many families have been with us for generations: today's parents were once our patients.
Why families choose us- Same doctor at every checkup
- Our own doctors on call 24/7
- Portal messages answered throughout the day
- We never turn away our patients
- Shared decisions, not just prescriptions
Academic medicine, close to home
Independent, with Mount Sinai behind us. The best of both worlds.
All of our doctors are Mount Sinai faculty, and we work closely with specialists there to coordinate your child’s care when needed. Because we’re independently owned, we can also connect you with the right specialist anywhere in New York City. Our office is a national model for pediatric medical education, where medical students and residents learn evidence-based medicine alongside the kind of personal, family-centered care that has always defined our practice.
- Faculty at Mount Sinai School of Medicine
- Newborn nursery rounds at Mount Sinai

What Upper East Side families say
Rated 4.5 out of 5 across 112 reviews on Google, Facebook & Citysearch.
“My daughter is 10 now and she's been with Dr. Cerasoli and Dr. Alpert since she was 5 months old. I can't ask for better caring, humble, supportive doctors and personnel. They always listen and don't judge even the minutest fears, and they've been very supportive through our triumphs and special needs. They always go above and beyond for their patients.”
“I have been bringing my daughter to this practice for over 15 years and there is nowhere else I would trust with her care.”
“Dr. Larsen saved my son's life a few years ago when he got a rare form of cellulitis on his foot at camp.”
“I've been taking my daughter here for 3 years to see Dr. Cohen. I've had a great experience at this office and I'm happy to share that! My daughter loves all the toys, books & the fish tank in the waiting room. Very nice people here!”
“I am extremely satisfied and grateful for the pediatricians in this office!”
“I have both my children seen here. Uptown Pediatrics has had my kids since they were 3 days old, and 16 years later we're still here with the same doctors and staff.”
