they are very attentive in helping us schedule and remember appointments when it’s time for our follow-up visits.

My experience at this place has been excellent with my three-year-and-seven-month-old daughter since she was born and my eight-year-old son, who has been going there since he was four. I've been to both the Lawrenceville and East Windsor locations. They are very attentive in helping us schedule and remember appointments when it's time for our follow-up visits, and the doctors take their time with the children and are genuinely concerned about their well-being and making sure they are up-to-date on everything they need. On my last visit, there was a nurse named Honesty who was very kind to my children and to me. The receptionist was also very polite, and all the doctors have been excellent. I only remember the names of Dr. Brian Marcus, who was the last one to see us and was very gentle, patient, attentive, and polite, and Dr. Sabeen Siddiqui, who is our favorite.

Dr. Marcus is so amazing with my babies.

Can’t recommend this practice highly enough. I’ve been taking my kids here since their first newborn appointment, and every experience is better than the last. The desk staff is kind, welcoming, and warm. They truly love the kids. As for the doctors, Dr. Marcus is so amazing with my babies. I always have a million questions, and he answers them patiently every time. He’s a great doctor. This is the only practice I’ll take my kids to.
