Two decades ago, IAQ Radio set out with a simple but critical mission: to build a bridge between science and practice in indoor air quality, building science, and disaster restoration. Every Friday at noon ET, hosts Joseph “Radio Joe” Hughes and Cliff “The Z-Man” Zlotnik have brought you long-form conversations with the experts, innovators, and thought leaders shaping these industries.
IAQ Radio has been “The Voice of the Indoor Air Quality and Disaster Restoration Industry" for 20 years and is the longest-running, continuously produced live technical podcast in history. We’re celebrating 20 years by doing what we do best—and what we plan to keep doing for years to come: long-form interviews with brilliant people exploring the science, challenges, and innovations shaping indoor air quality, disaster restoration, and building science.

For going on 20 years, Don has been a regular contributor to IAQ Radio, and over that time we have developed a strong friendship and professional relationship. Few people have given as much back to the indoor environmental quality and industrial hygiene community as Don and his wife, Lan Chi Nguyen Weekes, who is a legend in her own right.
Together, Don and Lan Chi built and successfully sold a consulting practice that they operated for 13 years. Along the way, both have devoted countless volunteer hours to professional associations, industry initiatives, and causes that have helped advance the fields of IEQ and industrial hygiene.
