Always nice to work with
Positive in approach. Answered all my questions. Efficient and professional.
Wait time was a bit much, 20 minutes after my appointment time. Stitches were taken out in 10 minutes and another 21 minute wait to have things frozen. If they were short staffed they should have said something. This has never happen to me before there.
She is very helpful and kind. She explains everything
Thank you. Awsome
