Jeff Gill

Jeff moved to the Rogue Valley with his family in the 1990’s to raise his three children here. Many folks in town remember Jeff for coaching volleyball and basketball in previous years. After a successful venture in home inspections and pest control, Jeff moved into indoor air quality, duct cleaning and a passion for saving energy in homes throughout the rogue valley. Jeff grew Gills Indoor Air Quality from three employees to over twenty in three short years. In 2010 Gills saved over 1 million kilowatt hours by doing weatherization on over 5000 homes here in the valley. That was more than any other contractor in the state.

After a bit of time off, Jeff is back to saving energy and saving money for home owners in the valley. His focus is primarily testing homes and training others to do the same.

Kathleen Patton

Kathleen moved to the Rogue Valley in the mid 1990’s. In 2010 she joined Gills Indoor Air Quality in the sales department. That is where the passion for saving energy and saving people money and actually doing something to help protect our plant began. Kathleen has become certified as a building analyst, and traveled the country pursuing an education in this field. She is excited about the projects going on here, creating jobs, training and testing homes for energy efficiency.
