Meet Christine Zahler, CPNP

Christine Zahler, CPNP, has dedicated more than two decades to caring for children and families.

Born and raised in Brooklyn, Christine earned her Bachelor of Science in Nursing from Stony Brook University and began her career at Mount Sinai Hospital, where she spent six years as a pediatric registered nurse caring for children with cancer, blood disorders, and complex medical conditions. She later earned her Master of Science in Nursing from Hunter-Bellevue School of Nursing and became a board-certified Pediatric Nurse Practitioner in 2008.

After beginning her career as a Pediatric Nurse Practitioner in New York City, Christine returned to Long Island and spent nearly 12 years caring for children and families at Port Pediatrics in Port Washington. During those years, she developed lasting relationships with generations of local families and became deeply connected to the community she also calls home.

When Port Pediatrics closed, Christine continued practicing locally, but she quickly realized how much she missed caring for children in her own community—and how much she wanted to return to the families she had known and cared for over so many years.

From that realization, Port Care Pediatrics was born.

Opening her own pediatric practice in Port Washington felt like coming home. With the unwavering support of her late mother, her husband, and her three children, Christine turned a longtime dream into a reality: a pediatric practice centered on personal relationships, thoughtful medicine, and the kind of care she would want for her own family.

Christine is grateful to once again care for the children of Port Washington and the surrounding communities—and especially honored to continue caring for families who have trusted her with their children over the years.

When Christine is not caring for patients, you will likely find her in the kitchen cooking for family and friends—or at a nearby court or field, proudly cheering on her three children.

Meet Kristin Gullo, CPNP

Kristin Gullo is a board-certified Pediatric Nurse Practitioner specializing in the care of children from infancy through adolescence and young adulthood. She cares for common pediatric conditions such as asthma, allergies, and infections, and performs simple procedures including vaccinations, ear wax removal, and minor wound care.

Kristin earned her master’s degree at Lehman College, where she completed specialized training in pediatrics. Her preparation helps her provide high-quality, compassionate care to every child and family she meets.

Growing up on Long Island as the firstborn child of immigrant parents, Kristin learned early the importance of hard work and understanding diverse backgrounds. She maintains strong clinical relationships with mentors and fellow local pediatric clinicians, and follows AAP and NAPNAP guidelines and protocols to stay current with best practices in pediatric health and wellness.

Outside of work, Kristin is the proud mom of three young boys who keep life lively and fun. She enjoys spending time with her big family, exploring new activities and adventure parks, and staying active in local communities.

Kristin looks forward to welcoming families to Port Care Pediatrics and making a positive impact for children and families across Long Island.

Your child isn’t just our patient. Your family is part of our practice.
