  The MAJORANA Collaboration has completed construction and is now operating an
array of high purity Ge detectors searching for neutrinoless double-beta decay
($0\nu\beta\beta$) in $^{76}$Ge. The array, known as the MAJORANA DEMONSTRATOR,
is comprised of 44 kg of Ge detectors (30 kg enriched to 88% in $^{76}$Ge)
installed in an ultra-low background compact shield at the Sanford Underground
Research Facility in Lead, South Dakota. The primary goal of the DEMONSTRATOR
is to establish a low-background design that can be scaled to a next-generation
tonne-scale experiment. This work reports initial background levels in the
$0\nu\beta\beta$ region of interest. Also presented are recent physics results
leveraging P-type point-contact detectors with sub-keV energy thresholds to
search for physics beyond the Standard Model; first results from searches for
bosonic dark matter, solar axions, Pauli exclusion principle violation, and
electron decay have been published. Finally, this work discusses the proposed
tonne-scale $^{76}$Ge $0\nu\beta\beta$ LEGEND experiment.
