    Dr. G and her staff are always great. We trust Dr. G for guidance for our little one and appreciate her candor and openness to hearing our concerns. She gets to know both the child and the family. The front desk staff is always friendly and accommodating. Medical assistant Sabrina and Nurse Amira are always super friendly and have great skills in doing hard things like vaccines with children. I am glad we chose this office to be our pediatrician.
