“My membership gave me a discounted rate for the symposium. That gave me access to a huge network of experts who had seen the things I was running into the field, and gave me great counsel to avoid costly mistakes.”

“From nurturing my passion for radon to leading the MD chapter, the IEA Symposium has been my fuel. It’s where curiosity meets expertise, and passion meets purpose. Learning from industry pioneers and meeting like-minded professionals ignited a spark in me.  I hope to see you in Florida!”

“As IEA members, attending the symposiums at a discount each year, give our NRPP Certified staff a great opportunity to mingle with other radon specialists from across the globe, and also stay current about changes within our industry.”
