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.

"We drive an hour so they can see the best of the best. I’ve never had a doctor who is so exceptional and attentive. He takes the time out to make sure my children are receiving the correct care and follows up with solutions to any issue at hand. He is hands down the best doctor we’ve had. " C.C., Clinton

"Dr. Flynn has a positive aura around the kids. I have twins and he’s always so calm, patient and understanding- even when both kids are crying. He never rushes us and allows me to ask my list of questions for each child. He listens to my concerns and addresses them. He’s never made me feel like my concerns are dumb. He was also very cautious and transparent when COVID hit and I’m appreciative for the email updates that his office sends. I highly recommend Dr. Flynn! " C.R., Cedar Grove

"Dr. Flynn is the perfect example of someone who works with his heart. As a mother of a child with a rare condition that required brain surgery and for her to be in home instruction at times, I wouldn’t be able to get through it without his help. He made sure to connect with all her specialists and even the school nurse for her to be put on a safe plan at school. It gave me so much comfort to know that I can call his practice and he would take the time to get on the phone to speak with me instead of the secretary. He is very compassionate, knowledgeable and caring. I am always happy to refer him to anyone who is looking for a doctor. Dr. Flynn really impacted our lives and we wouldn’t be able to get through the toughest moments without his help. God bless him and his family always. " D.M., Newark

"He is AMAZING with my three children. He takes the time and does not rush through our visits. He makes sure that myself and my children understand why certain bloodwork is being done and the benefits of vaccines. He makes sure that I am involved in my children’s care and that medical decisions are never one sided. Dr. Flynn is the ABSOLUTE BEST!!! " J.M., Bloomfield

"Dr. Flynn has never said no to a sick visit for my children. He has been the best pediatrician I’ve found and I’ve lived in 3 states since becoming a mother. He’s the best. I have a 17 year old daughter and 11 year old boy girl twins. I even sent my sister-in-law to Dr. Flynn for my niece and nephew when they moved to the area. Dr. Flynn is honest and straight forward. He will tell you exactly what is needed for any concern I’ve had. Thank you Dr. Flynn! " K.S., Newark

"I have a teenaged daughter who is really shy and does not like going to the doctor however Dr. Flynn has a way of communicating with her and explaining things to her in a way she can understand and is more at ease with her visits. He also makes time to return calls to advise us of over the counter medication we can get where applicable. " L.W., Bloomfield
