  The MAJORANA DEMONSTRATOR is searching for double-beta decay of $^{76}$Ge to
excited states (E.S.) in $^{76}$Se using a modular array of high purity
Germanium detectors. $^{76}$Ge can decay into three E.S.s of $^{76}$Se. The
E.S. decays have a clear event signature consisting of a $\beta\beta$-decay
with the prompt emission of one or two $\gamma$-rays, resulting in with high
probability in a multi-site event. The granularity of the DEMONSTRATOR detector
array enables powerful discrimination of this event signature from backgrounds.
Using 21.3 kg-y of isotopic exposure, the DEMONSTRATOR has set world leading
limits for each E.S. decay, with 90% CL lower half-life limits in the range of
$(0.56-2.1)\cdot10^{24}$ y. In particular, for the $2\nu$ transition to the
first $0^+$ E.S. of $^{76}$Se, a lower half-life limit of $0.68\cdot10^{24}$ at
90% CL was achieved.
