NYC Pediatricians & Pediatric Care

We understand parents, because we're parents too. We know the stress that a sick child can cause. We've experienced the panic that comes right after realizing we forgot to get our kid's health forms completed. We love the idea of calling a trusted friend in the middle of the night, just to make sure we're not missing something. And we've wished we could email our pediatricians, rather than picking up the phone.

That's why we are proud to offer pediatric care to our New York members. One Medical takes the hassle out of pediatric care by offering same-day appointments, direct email access to your doctor, online appointment scheduling and 24/7 virtual care.

Our team includes a board-certified pediatrician and experienced providers; together they are able to care for both you and your children. The office has been designed for both kids and adults, with family-friendly exam rooms, a Nurture Room for breastfeeding and newborn care, and plenty of space for stroller parking. For those arriving by car, there is nearby garage parking. Our goal is to ensure that you and your child's entire experience, from arrival all the way through departure, is seamless and worry-free.

Pediatric patients can visit our Park Slope office, conveniently located at 794 Union Street, near the corner of 7th Avenue in Brooklyn.

To register your child for One Medical membership, call 212-441-4383 or contact our pediatric care team by completing the form to the right and a member of our team will follow up with you shortly.

What is One Medical's approach to pediatric care?

We understand that children don’t always like going to the doctor. That’s why our approach to pediatrics removes the stigma associated with a doctor’s office visit. We’ve thoughtfully designed both the physical space and the visit experience, and have given our providers the time and tools to connect with your children.

We want your kids to be comfortable and engaged with their health so that we can help them grow into thriving adults. We think your kids can enjoy their trips to the doctor and start a lifelong health partnership.

What should I expect from a pediatric visit?

We’ve built a positive and collaborative wellness home for you and your family. When you walk into our office, you’ll be greeted by one of our friendly team members, who can help you coordinate your family’s health care, including your in-office visits, camp physicals and specialist referrals. You’ll spend your entire visit with a board-certified pediatrician or family doctor who can care for your entire family.

Our providers are eager to build strong and lasting relationships with their patients. They want you to feel comfortable sharing your parenting experiences during visits, emailing them questions, and calling our practice for questions about something as sudden as a fever or as routine as a well check.

What conveniences are offered at the Park Slope Family office?

We offer same and next-day appointments for when your child needs to be seen soon. We also provide email access directly with your child’s provider, as well as 24/7 phone support from our Virtual Medical Team to help with immediate questions and after-hours support.

Additionally, our on-site lab supports blood work and immunizations. It’s just one more way that we’re trying to fit right into your busy schedule.

How do I register my child for pediatric care with One Medical before she/he is born?

First, fill out an interest form and a member of our team will follow up with you to register your baby. We’ll collect some basic information during enrollment, but don’t worry if your baby doesn’t have a name yet - we’ll update the chart with any new information after he or she is born.

Within a day after your baby is born, give us a call to book his or her first appointment. The first well visit with your baby’s provider is typically scheduled for three days after your baby leaves the hospital. Remember to budget extra time to get out of the house with a newborn.

What Additional Support Do You Have For New Parents?

In addition to traditional pediatric care and our 24/7 support team, we are also pleased to be able to offer breastfeeding and lactation support. Our on-staff Lactation Consultant is available for 60 minute lactation consulting sessions to help you with a range of feeding solutions including breastfeeding, breast pumping, bottle feeding and weaning. Her personalized approach has been well-received by our families, and her appointments are typically billed through insurance.

Members can schedule lactation consulting appointments by calling our office at 212-624-1077 or emailing

Should I see the same provider as my child?

Choosing one provider for the whole family offers greater convenience and a more holistic healthcare experience. Your provider will have an understanding of your family’s health history and values to better treat you and your child. That said, it’s not necessary and you are always able to visit with any of our providers in any of our offices, since all of our providers have access to your secure, electronic medical records.

How much does this cost? Are there family discounts?

Membership to One Medical is $199 per year. This fee allows us to provide services above and beyond what insurance provides.

We do not currently offer discounts for families, although this is something we are considering. We are confident that you’ll find the experience worthwhile, but if you are ever unhappy, please let us know and we can refund your membership fee.

How do I sign up?

We want to make sure we're able to address all of your concerns and want to make your registration process as simple as possible. To help you register your child, please call us at 212-441-4383 or complete the online interest form on this page. A member of our pediatric care team will follow up with you shortly to help register your child and assist with scheduling any appointments.

Penelope Hsu, MD, Park Slope

"I enjoy partnering with families in taking great care of their children. By maintaining open lines of communication inside and outside the office, I aim to create a space where kids and parents can share honestly about their needs. From infants to teens, children are so important, and I want them to know they can trust me with their health care.”
