Geotherm USA



Geotherm started 1978 as as one man operation by Deepak Parmar in Canada.  While at Ontario Hydro Research, Deepak worked on a research project sponsored by EPRI to help design a fully automated and portable test instrument for the measurement of  thermal properties of soils and backfills.  Over the years, in house research and development has resulted in designing state of the art test instrument (TPA2000) and accessories (lab, field and marine thermal probes) that have long been accepted as the "industry standard".

In 2000, Geotherm formed a joint venture with The Garde Group in Australia operating as Geotherm Australasia under the leadership of Phil Garde.   Geotherm Australasia specializes in providing thermal resistivity testing services for the Australasian Market.

In early 2004, the company opened its first office in the United States in Chandler, Arizona headed by Geeta Parmar and Nimesh Patel.

As the company grew it moved again in 2008 to its present worldwide headquarters in Dublin, California operating as GeothermUSA.
