Dr. Gerrits was extremely professional, patient, caring and knowledgeable. He was able to explain some difficult concepts in ways that didn't make my child uncomfortable or overwhelmed.

He makes my kid feel seen and listened. He is great explaining actual situation and next steps and helping us not worry. With him we feel that all is under control.

Would love to find a different endocrinologist for my children, but worry about continuity of care.

Dr. Gerrits showed compassion to all questions and was very thorough as well as interacted with our son vs only address our concerns

It really meant a lot that doctor himself personally called to give me test results. I know doctors are busy.
