Sadie is our office cat.  Sadie adopted our office and has become a permanent staff member here.  She takes her many jobs in the office very seriously.  She will generally be the first one to greet you, she'll walk you to your treatment room, and even assist by keeping you company (or warm) such as here with a patient icing.  She'll even go as far as assisting at the front desk in collecting your co-pay.
