A FIVE STAR MEDICAL PRACTICE !!
Samuel R. Williams, MD and Lisa W. Petit, MD and the staff welcome you.




A Five Star rating is the highest rating that can
be given to a medical practice. We are a Five
Star rated medical practice. Who rates medical
practices?

First, and most importantly are the patients.
Patients complete evaluation forms from the
health plans and also submit evaluations to
various web based evaluation sites. Our
patients have given us a 5 star rating and that
explains why patients rarely transfer from our
practice.

Second, health plans conduct their own
evaluations of participating providers. For
example, Carefirst ranks us 5 out of 5 stars.
Aetna, which uses a 4 star system, ranks us 4
out of 4.

Third, the state has two health agencies
evaluating medical practices, and we have
consistently received very high scores.

WHAT IS IT THAT MAKES US A 5 STAR PRACTICE?
