    Dr S is the best, as always. He listened, he explained his thoughts and even called me the next day to check in on my child. He's truly a gem who cares deeply for the kids in the community!

    I just adore Dr Sullivan. My daughter was nervous about her checkup so he gave her stuffy a full checkup first and it was so useful for her to see what was going to be done. I give him an 11 out of 10.
