    I went in and was seen very quickly by Stephanie Davis. She was kind and professional, examining a couple moles I was nervous about. She had a very polite assistant as well(whose name i cannot recall unfortunately). Even the front desk lady was amazingly kind and everyone was welcoming. Very professional and quick.
    Went to the Sherman location.
