— Review regarding Mercy Clinic Family Medicine - Clayton-Clarkson"When you call to schedule an appointment you are sent to Washington, Mo where they schedule everything for the 'satelite' offices such as clarkson/Clayton. Allow yourself plenty of time and patience as the women who answer are not the sharpest tacks."

I was given a whole packet giving me the best directions... Any questions I ever had, they always made sure to sit and talk me through the surgery!"
