Ruby Dhillon-Williams, J.D. began serving as Interim Director of the Arizona Department of Housing (ADOH) in March 2025. She previously served as Deputy Director and, from 2020-2022, Assistant Deputy Director of Housing & Community Development for ADOH overseeing Rental Development, Community Development & Revitalization, Special Needs Housing and Asset Management. Prior to that, she served as a rental programs administrator from 2010 to 2012.

In her current role, Ruby is responsible for ensuring affordable housing is available for all Arizonans. She oversees programs established to create, preserve, and invest in affordable housing statewide.

Through her process improvement expertise, Ruby played a key role in streamlining the federal Low Income Housing Tax Credits (LIHTC) award procedure and eliminating duplicate processes and excess regulation. In 2022, this resulted in the most applications for affordable housing projects (33) in the history of Arizona, with an 80% increase in applications from rural Arizona communities and a record amount of LIHTC dollars ($30.1 million) awarded. She was also the agency lead in rolling out the State Tax Credit program within three months of Governor Ducey signing the legislation into law.

Ruby is a progressive leader with over 20 years of experience in public and private sector housing development and an extensive background in utilizing the LIHTC program. In addition to her previous service at ADOH, Ruby served as Vice President of Operations at Global Premier Development, Vice President of Acquisition at Alliant Capital, and Vice President of Development at Integrity Housing. She was also a co-founding partner of Newport Southwest, LLC, a development entity focused on the construction of LIHTC properties.
