Doctor Pi's official Clinic portrait!

She is the fifth clinician: in addition to holding the standard title of DDS, like me, she is also a certified DON, Doctor of Oral Nutrition, and the head of that department within the EDC. Instituting strict mouth-friendly diets for everypony, developing recipes that include the highest quantities of teeth-strengthening nutrients as possible while excluding all substances that are detrimental to tooth health, and serving the chief architect of one of the Clinic's most important projects- completely destroying every last trace of the disgusting, tooth-rotting sugar scourge, and abolishing its existence and memory from Equestria forever. She hates sugar with every fiber of her being, and remembers this always being true. No recollections of baking or selling cakes linger within her purified mind, except in the deepest realms of the subconscious.

(I have yet to decide much about how she was converted, but I will eventually!)
