About Us

I/H/R Research Group was founded in 1976. Originally located in Orange County, California, I/H/R’s data collection and programming operations were moved to Las Vegas, Nevada to take advantage of the abundant skilled labor force in that market. Located directly across from the UNLV campus, the operation also draws from the large university population.

As one of the original marketing research data collection and support operations founded by seasoned research professionals from the full-service side of the industry, our clients benefit from, and rely on, project management by staff who have in-depth knowledge of research design, sampling and analysis.

I/H/R Research Group provides exceptionally high quality, cost-effective telephone, online, mixed-mode and mobile data collection, plus all support services – on a direct or sub-contract basis to research buyers. Our founding premise was to provide corporate and research company buyers with competitive pricing with no compromise in the quality of product, service, or deliverables timeline. We continue to stand by that philosophy today.

In fact, our family of companies works to provide you the best TCPA compliant option available. Click here to find out more!
