Our mission is quite simple- to deliver the best quality care to our patients as possible. We treat all of our patients and
parents with love, kindness, and understanding.

As we treat our patients and have to make decisions, we always ask ourselves "What would I do if this were my child?". Any
decisions we make, are exactly what  we would do for our own children.

We insist that the entire staff treat everyone with the utmost of respect, kindness and understanding.

IMMUNIZATIONS
We believe that all children should be immunized. However, we are willing to work with parents who want to follow a
different schedule.

ANTIBIOTIC USE
We evaluate each case individually. If we feel your child needs an antibiotic, we will explain our rationale. We also will
explain to parents why we think a patient doesn't need an antibiotic.
