Carrissa is the absolute best!!!!!!!

10/21/2025

Carrissa is pleasant and amicable. She does get at her job efficiently, but I often have questions, and she does move quickly to the next patient. I prefer not to interrupt her while she is examining my skin or doing a procedure, so a question & answer period before or following an exam would be welcomed. I did manage to have my questions addressed by the attending nurse.

She is very kind and caring and it's a pleasure to have her as my provider. She's very thorough.
