Welcome back to all who attended the 85th Annual Conference and Exposition in Niagara Falls, September 8-11, 2019. The great State of Arizona was well represented. Our very own Tim Boncoskey, Maricopa County Chief Deputy Assessor and 2019 IAAO President, convened over the festivities. Over 1400 property tax assessment professionals from around the world were in attendance to stay abreast of advances in our industry from technology, to ethics, legal matters, education and experience, automated valuation models and other topics. Every session left attendees with tools and strategies to continue on our mission of fair and equitable values that benefit our communities. A marvelous time was had by all. Jennifer Rearich, Maricopa County Regression Modeler, received her Residential Evaluation Specialist designation as well as the "Emerging Professional Award". Tracy Johnston, Maricopa County Chief Appraiser, received her Certified Assessment Evaluator designation. Congratulations to the Arizona Designation Class of 2019! The conference closed with Tim Boncoskey swearing and swearing and passing the torch to Amy Rasmussen as the IAAO 2020 President!
