AARA Doctor Clayton

She is a native of Maryland’s Eastern shore and is thrilled to be raising her children there. In her free time, she enjoys reading, boating, cooking, and spin classes. Like any true Marylander, she hasn’t found any seafood that she doesn’t love.

She fell in love with rheumatology because of its diagnostic challenges and the patient relationships that come from chronic disease management.
