“Amazing Staff, Amazing Dr. She calmed my son in a way no other Drs have been able to. He has a serious needle phobia. I was extremely impressed. I really hope his toe trouble is over but if isn’t we will go straight back there. They were awesome!”
“I have gone to see Kristin Sands before and she always takes such great care of me. Today I brought the little in for a visit and she once again gave me options, told me not to worry it wasn’t what I thought it was and how to fix his skin issue. Love her! The practice was friendly and we were in pretty quickly.”
