“Gaby’s unrivaled institutional knowledge of IAPMO’s history and operations have served the association immeasurably for the past 25 years, while Tom’s expertise and initiative have opened numerous new opportunities for The IAPMO Group to grow and thrive commensurate with his fast rise within our organization,” said IAPMO CEO Dave Viola. "Congratulations, Gaby and Tom. These promotions are well deserved and will strengthen IAPMO for years to come.”

Mr. Nunez began working for IAPMO in January 2020, following almost two decades as a field services representative with the state of California, where he most recently served as the Southern California area manager for the Construction Inspection Management Division. He has served on IAPMO’s board of directors for 13 years, including as president in 2017 and 2018.

He helped IAPMO earn the President’s “E” Award for Export Service in 2019, after securing a federal grant intended to increase the competitiveness of the U.S. plumbing industry abroad by generating exports to Indonesia. Mr. Lindsay also works with the International Water Sanitation and Hygiene Foundation (IWSH), IAPMO’s nonprofit organization that supports water, sanitation, and hygiene initiatives around the world.

“We are fortunate to be able to promote these highly qualified, knowledgeable people to these senior positions within our organization,” said Mr. Viola. “IAPMO is well positioned to cement our status as a leader in the plumbing and mechanical industries for years to come. Congratulations, Tony, D.J., and Christopher.”
