Who We Are

Valerie Simone

Valerie Simone is a process improvement and project management professional with over 20 years in the real estate, financial services, healthcare, and automotive industries.  She graduated from The College of William & Mary in Virginia with a bachelor’s degree in economics and math, and she obtained her master’s degree in business administration (MBA) from the University of Michigan, where she founded the Business School Environmental Society.  Her MBA studies and subsequent role as a buyer for Ford Motor Company introduced her to the Toyota Production System (TPS; aka “Lean”), which she observed was a superior system for allowing organizations to operate and grow while maintaining “best-in-class” levels of safety, quality, delivery, cost, and morale.  She continued her studies at the Georgia Institute of Technology, obtaining a Six Sigma Black Belt and wrote a textbook for her Six Sigma professor.  She joined a financial services start-up (eventually purchased by Goldman Sachs), where she developed and launched a continuous improvement training program with support from her TPS/Lean teacher and mentor, Steve Hoeft.  Valerie taught hundreds of leaders and front-line professionals the value of “Respect for People” and “Continuous Improvement,” TPS’s two main pillars.  She also taught Business Process Modeling Notation (BPMN) 2.0 to her students as part of documenting, implementing, and improving processes.

What is an Earthship Home?

An Earthship is a type of passive solar house that is made of both natural and upcycled materials (such as earth-packed tires). Earthships can be completely off-grid or partially off-grid.

Earthships can be built in any part of the world, in any climate (with a permit) and still provide electricity, potable water, contained sewage treatment and sustainable food production.

Earthships are thermal mass homes first, passive solar homes second.

Whatever temperature goes into an Earthship, it will hold… and since it is also a Passive Solar House, it is also very tight and interacts only with the sun and the earth for heating and cooling, providing stable comfort year round in any climate. This results in being able to provide a sustainable home on property that may not be situated to the ideal of 13.5 degrees east of south.
