TACOMA, Washington --Medical Imaging Northwest (MINW) and Diagnostic Imaging
Northwest (DINW) with corporate/administrative operations currently located in Lakewood, WA,
will be moving to a new downtown address in the Wells Fargo Building on Pacific Avenue, as of

timing in the real estate market allowed for us to negotiate a mutually beneficial agreement for
our group and Unico.  Along with improved connectivity and security, the Tacoma location also
places us closer to many of the area’s healthcare and business leaders.”

“We are pleased to have Medical Imaging Northwest/Diagnostic Imaging Northwest join the
growing core of South Sound medical professionals in Tacoma,” said Tacoma Mayor Marilyn

Edmonds Family Medicine. DINW represents the three joint-ventured, outpatient imaging centers
under the name Diagnostic Imaging Northwest located in Bonney Lake, Puyallup and Sunrise. All

strong, we continue to improve efficiencies with centralized scheduling, pre-registration, billing,
transcription, operations and a management team all working together to enhance the ability of
our Radiologists and technical staff to provide high quality diagnostic and interventional imaging
