Review by Pamela ***** March 5, 2026

5/5
I have been a patient of Dr. Sago for about 10 years. She provides excellent treatment, educates her patients about skin diseases and is very kind and patient. Taking her time and listening to her patients is a gift to us and also to the numerous residents she had with her. She is teaching them the RIGHT way to be a physician and never once looked at her watch. I could not be happier!
