Dr Cavanagh as bedside manner is absolutely amazing- he's so soft spoken which soothes and makes our children comfortable during their visit. He listens intently to our concerns and explains things in a way for us to easily understand

He took his time to make sure everything was addressed, and proposed a treatment plan explaining everything to myself, and the kids. He really included both parent and child in the plans. We have no complaints at all.

Dr Cavanagh is awesome. Patient and good listener. Answers my questions. Explains things well. Took a good amount of time to really listen to my son's lungs to rule out pneumonia- super thorough exam.

We love Dr. Cavanagh and feel truly that our child is in good hands with him as her pediatrician. She has been coming here since day 1. They are quick to call back with any questions we have along with scheduling if she is sick. We feel truly cared by Dr. Cavanagh and staff.

The staff consistently demonstrates kindness during my children's visits, from the receptionists to the medical assistants and Dr. Cavanagh. Their welcoming demeanor creates a positive atmosphere that enhances the overall experience.

Dr. Cavanagh is truly the best pediatrician. He has a natural way of putting both parents and children at ease. His playful, gentle approach helps kids feel comfortable and even excited about their visits. As a parent, I always feel confident in the care he provides, and my children absolutely love him
