Pediatrics and Adolescent Medicine
At Mount Sinai Doctors Five Towns, our pediatricians provide high-quality medical care in a warm, family-friendly setting. Whether your child is running a fever or simply due for a check-up, our accomplished pediatric team is pleased to put their decades of experience to work for you.
Pediatric and Adolescent Medicine
Our experts in children’s health are highly skilled, providing the best possible preventive and sick care. We are experienced in evaluating and treating symptoms that include fever, sore throat, cough, headache, ear pain, stomachache, spitting up, vomiting, diarrhea, constipation, diaper rash, injuries, and wheezing. We also provide all immunizations, growth assessments, attention-deficit hyperactivity disorder (ADHD) evaluations, blood tests for allergies, and testing for sexually transmitted diseases, if appropriate.
If your child is diagnosed with a condition that requires in-depth attention—such as asthma, diabetes, cerebral palsy, spina bifida, or epilepsy—we can provide referrals to the best pediatric specialists in the area. We also make recommendations for skin testing for allergies, physical therapy, occupational therapy, speech therapy, hearing tests, and gynecologic care.
Pediatric Gastroenterology (Digestive Diseases)
Mount Sinai Doctors Five Towns provides expert diagnoses and treatments for a range of digestive diseases in children, including inflammatory bowel disease, celiac disease, short bowel syndrome, abdominal pain, failure to thrive, gastroesophageal reflux, constipation, and liver and biliary disease. In addition to medical and dietary management of common digestive conditions, our pediatric gastroenterologist, Joanne Lai, MD is skilled in providing diagnostic and therapeutic endoscopic procedures (the use of special instruments to look inside the body), as well as the newest treatments for pediatric inflammatory bowel disease. Our team also strives to build an open, comfortable relationship with each of our patients and their families, taking the time to fully explain all treatment options and answer all questions. Through this blend of comprehensive care and compassionate attention, we are committed to helping each child in our care achieve the best possible long-term health.
We Answer Your Questions
Our pediatric team takes the time to establish a relationship with you and your family so that we may provide the very best long-term care. We understand that parents have many questions about their children’s health on topics that include allergies, antibiotics, behavior problems, breast-feeding, dental care, vaccines, medications for ADHD, and growth milestones. We will take the time to answer every question you may have.
We see adolescents aged 13-18 without their parents in the room and answer their questions confidentially. This opportunity for teens to discuss their concerns privately creates patient trust and optimal care.
