Kevin Padden
Kevin has been active in tile & stone for most of his adult life. Since his father was in the industry at the time of Kevin's birth, he can truly claim that he was "born" into the business. Since following his father into the tile & stone business in 1978, he was owner of Padden Tile & Stone for ten years, prior to relocating to Arizona in 1992.

In the time he has been in Arizona, Kevin has worked in every aspect of natural stone fabrication, production, sales, estimating, education, operations & overall general management. He has been instrumental in directing the establishment of multiple fabrication shops in the Phoenix area.

Kevin's passion for education has led him to be a regularly featured seminar presenter at StonExpo & Coverings, and has been a contributing writer for national publications serving the natural stone industry. Kevin serves as the MIA Training Specialist.
