At Step By Step Pediatrics, Dr. Sean Flynn ensures that every child feels like the most important person in the room. “Every patient, every concern and every question matters to me,” says the father of two, who’s been nominated as a New Jersey’s Favorite Kids’ Doc for the past five years. “Communication is key in everything we do.” In his bright, colorful office, patients and their families are always greeted with a smile. The practice offers a patient portal for parents, as well as TV and movies to put kids at ease. “I’m a big kid at heart, so I make it a point to talk to all of my patients,” he says. “I’d never suggest anything for any patient that I wouldn’t do for my own child.”

A board-certified pediatrician and Fellow of the American Academy of Pediatrics, Dr. Flynn received his MD at East Carolina University and completed his pediatric residency at UMDNJ-New Jersey Medical School. He trained at University Hospital and the Joseph M. Sanzari Children’s Hospital at Hackensack University Medical Center. “I love what I do and feel privileged to be able to live my dream and serve this community,” he says.

"When I first chose him as a pediatrician, it was for my daughter, who was an only child at the time. Dr Flynn has seen me become a parent to two more. Each time at that first newborn visit, he'd inquire about my new baby in a way that made me feel proud. He knows each of my children by name. He’s made me as a parent feel that he genuinely cares about my children and their health. " ~Saidah, Newark

"Dr. Flynn is very thorough. He's attentive to my daughters' needs and is also among many others who are very knowledgeable about medicine and every patient. Although his practice is growing, I still feel like he takes the time and patience needed with my daughters concerning their health. " ~Ayesha, Newark

"Dr. Flynn handles my daughter's special needs in a way that puts me at ease and makes her feel like a normal kid. I can call him 20 times in a week and he never makes me feel like I'm asking a stupid question or overreacting. He’s very kind and sweet and puts our entire family at ease. I trust him fully and honestly feel that he genuinely wants the best for all of my kids. Thanks, Dr. Flynn! " ~Maureen, Kearny

"As a first-time mom, I have a TON of questions. He takes his time to answer all of my questions every single time we go to his office. I always feel comforted knowing that nothing is too trivial for him to answer. He always makes himself available to speak over the phone if you have any questions or concerns, and does his best to squeeze patients in when there could be something wrong. I love how much care he gives to each individual patient and their family. He's extremely thorough during his examinations and always makes sure to let us know how she's doing. He has an exceptional bedside manner, and I love that he has kids of his own so he can relate to all parents. So glad we found him! " ~Brittany, North Arlington

"I had a baby in March 2020 and Dr. Flynn was the pediatrician at the hospital. We stayed with him as a pediatrician because he is very straight forward with any concern you may have, even if it’s the silliest. At my daughter’s first month check up, we were already concerned about COVID-19 and he explained how his office hours were going to change to help parents and their kids be safe. His staff is wonderful. We feel so blessed to have him as our daughter’s pediatrician because you can tell he cares, never keeps you waiting, always answers our questions, gives us recommendations, is polite, super clean, and respectful." Alicia, Newark

"I have always been able to get an appointment when my children are sick. They have never been turned away and that means a lot to me. All testing ever needed is done in office for general medical or sick needs." Krystle, Newark

"I love Dr. Flynn! He and his staff are exceptional at making both my children feel comfortable. Any concerns or care that is needed is always available." Ebony, East Orange

"I met Dr. Flynn while in postpartum at Clara Maass. Everything about him put me at ease. I wanted a pediatrician that had a more private practice, where I wouldn’t have to rotate between doctors on call. I also wanted someone with patience, who was willing to spend time explaining things to us as new parents. I know with certainty that every time I walk into his office, I will get the same care and attention that every other patient gets. It is always a pleasure to see him, even when it’s because our daughter is sick. I’d also like to add that behind every great doctor is a great staff, and Dr. Flynn has an awesome one. From day one, Malet, his medical assistant, was incredible. They work really well as a team, and they always do their best to make you feel at home. Forever grateful for them!" Brittany, North Arlington

"I’m a seasoned mother and had a good rapport with our previous pediatrician (who’d cared for my older daughters). To our dismay, we discovered she was not a listener. She did not hear our concerns as parents and did not pay a attention to a close call with our newborn. We transitioned our newborn to Dr. Flynn and he’s been her pediatrician ever since (6 yrs). Shortly thereafter, we hesitantly transitioned our teenage daughters to him. We’d preferred to have our teenagers with a female but we found Dr. Flynn to be more than appropriate, knowledgeable and caring. He assess the situation, gives sound medical advice and the (few) times I didn’t agree he actively listened to my concerns and found medically sound alternatives. Dr. Flynn is a hard working, dedicated family man and a great doctor… We appreciate him in our family’s life" Qiana, East Orange

"In the little time I’ve been going to him with my kids, he has exceeded my expectations. I love the fact that at every visit my kids are not seeing a different doctor or PA in the office." Vanessa, Belleville
