Jill Johnson

Chief Executive Officer

Jill took an unconventional path to entrepreneurship. Born and raised in Prince Edward Island, she moved to Fredericton, New Brunswick and earned a Bachelor of Arts from UNB, and later, a Master of Arts from the University of Waterloo, in Waterloo, Ontario. The field of anthropology was Jill’s focus throughout university, studying the history of humankind, how the environment shapes the way we live (and vice versa), and how technologies will shape our future.

After moving to Nova Scotia in 2010, she started working for the provincial government. Seeing the potential of this technology, she left to become a co-founder of Neothermal Energy Storage, on a mission to provide a warm home with a lighter heating bill.

Outside of working on Neothermal, Jill gets out of bed for her three rescue cats and a great cup of coffee, and daydreams of summer days on Maritime beaches.


Louis Desgrosseilliers

Chief Research and Technology Officer

Louis grew up in North Bay, Ontario. He is a multidisciplinary heat storage expert and inventor, holding PhD and master’s degrees in Mechanical Engineering from Dalhousie University and a bachelor’s degree in Chemical Engineering from the University of Waterloo. Neothermal’s proprietary heat storage cell technology resulted from Louis’ NSERC-supported PhD research, from which he graduated in Fall 2016. Louis is passionate about promoting social and environmental well-being by developing an accessible cost and energy efficient indoor heating technology that the market has never seen before.

Louis likes to run and bike (when he has the time), and once biked 88 km in one day from Burlington to Waterloo just for the heck of it.
