After struggling to get my son's anemia under control with a different doctor, I made the switch to Dr. Cavalier. She genuinely loves kids and her job, my son is well again and when he does get sick he enjoys going to the doctor now! One time my son left a toy there, Doc and Christine (front desk) typed up the cutest email directed to my son pretending to be the toy. Honestly words can't express all the great things about Dr. Cavalier!

The best, BY FAR, pediatrician I have ever taken my twins to. She's patient, engaged, answers emails at all hours of the night and day, follows-up, incredibly thorough, highly intelligent, etc. Her staff is excellent as well. A couple times over the past couple of years I didn't have doctor visits covered by my insurance and she provided a TON of counsel to me for free so that I didn't have to pay for a doctor's visit out of pocket. Dr. Cavalier really is amazing.

About Me

Medical practices are increasingly pressured financially by rising healthcare costs and expanding healthcare legislation, and in turn respond with attempts to expand their patient base by scheduling as many patient encounters in a day as possible. &n...
