Mark Thiele


Mark Thiele is a houser who stands in awe of his colleagues.  “Safe, stable, affordable housing is the foundation on which we build healthy, happy and productive lives,” he says. “Despite significant headwinds, housers nationwide continue to provide the most vulnerable Americans with shelter and supportive services in sustainable communities. We need them to succeed. We need to invest in their success.” 

Before joining NAHRO, Thiele was the Interim President and CEO of the Houston Housing Authority (HHA). During his tenure, HHA focused on safety, increasing affordable housing, and innovation. The agency hosted numerous COVID-19 testing and vaccination events with local partners. It also added thousands of units of affordable housing through acquisition and development and earning the coveted Moving to Work (MTW) designation. 

Prior to that Thiele served as HHA’s Senior Vice President (SVP), overseeing Program Operations, Real Estate, Investment and Development, Policy as well as all of the agency’s support functions, including Finance, Legal, Procurement, Human Resources and Information Technology.  During his time as SVP, Thiele worked with the agency’s more than 200 staff members to be the premier provider of quality, affordable housing in Houston.    

For the previous eight years of his lengthy year career in affordable housing, Thiele served as the Vice President of the award-winning Housing Choice Voucher Program at HHA, which provides more than $155 million in housing subsidies each year, and is one of the largest voucher programs in the country.   In that role he supervised more than 120 staff dedicated to providing quality, affordable housing options for more than 18,000 Houston households via the regular Housing Choice Voucher, VASH, Mainstream, NED and Mod Rehab programs, as well as a plethora of initiatives funded by the City, County and other entities. The HCVP department played a significant role in Houston’s award-winning efforts to end homelessness. Thiele also worked in the affordable housing sector as a consultant at Quadel Consulting Corporation. 

Thiele has been a devoted NAHRO member for years, taking on a variety of leadership roles at the state, regional and national levels.  At national NAHRO, he served on the Board of Governors, as the Chair of the Board of Ethics and Credentialling Trustees, and as the Vice President of the Community Revitalization and Development Committee. Thiele also served as the Senior Vice President of the NAHRO Southwest Regional Council, and as the President of Texas NAHRO. He is a proud member of the Board of the National Public Housing Museum (NPHM).

Sean Gilbert

NAHRO Vice President Candidate

“Service to others is the rent you pay for your room here on earth” by Muhammad Ali is the bedrock that I have tried to build my professional career on.  It is my duty as a housing professional to give back to an industry that has given so much to me.  I am honored to campaign for the position of NAHRO Senior Vice President.

I am a proven leader at the local, state, regional and national levels.  I understand the importance of the brick and mortar of our properties, but also that these properties create communities that have been underserved, underfunded and disenfranchised.  Whether it is working with the local community to bring educational opportunities to the kids in our communities or making sure that Pre-schools and day care are available on site I have placed an emphasis on providing opportunities to our families.

I grew up in a coal mining town in southern West Virginia on the Kentucky border. I quickly learned the values of hard work, faith, community and family.  This is where I learned the vision and values that are so important to me.  Together we will base my campaign on STEAM.  Steam was so important in the town where I was raised.  Steam was the energy that was used to power the trains that delivered the goods from and to this region.  Steam gives you energy, direction and power.  I plan to use this energy, direction and power to effectively lead NAHRO.
