the doctor was knowledgeable about the rare condition that seemed to fit my child's symptoms. unlike my local pediatrician, Dr. Grimmer seemed to completely agree that she fit the pattern for periodic fevers and was happy to treat her based off of what we described.

We actually came to Dr Grimmer for a second opinion. The first doctor we saw from a different clinic did not address either of our concerns and recommended and pushed for surgery on something unrelated to the reason for our visit. Dr Grimmer was wonderful. He addressed both our concerns at the visit. He did not push for any surgery.

Dr. Grimmer is phenomenal! He listened to us, explained the procedure thoroughly and even checked on my son's tonsils for us even though we were there for an adenoidectomy. He explained and was patient when I had to ask for clarification on the procedure and after care for my son.
