Park Slope

Our Park Slope doctor's office is conveniently located on Union Street, and offers both pediatric and adult medicine. 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. We are committed to making access to high-quality care easy. That's why we offer same-day appointments that actually start on time, an in-office laboratory, and access to our 24/7 Virtual Care Team who can treat you whether you're at home or on the go. Our team is trained to help with everything from coughs and colds to chronic conditions, and can also provide immunizations and vaccination, as well as pregnancy and fertility care. With One Medical as your primary provider, you can rest assured that you and your family will be taken care of.
