Infection Protection with a Purpose

Almost a decade ago, the Science-Proven Microbial Control® program was created to bring WELL building best practices to the Cleaning and Building Maintenance industry.

Our vision has been to help everyone feel 100% confident their buildings are protected for all stakeholders; such as our employees, building occupants, owners, and managers.

From day one, stakeholder capitalism has led us to use powerful yet safe EPA-registered disinfectants when the industry norm was to use less expensive cleaning agents.

Greg Theroux Found CEO SPMCglobal

Founder & CEO

Greg attributes his business success to a commitment to people and attention to emerging technologies. For over 40 years he has been a driving force in building maintenance companies throughout the nation, ranging from billion-dollar, Fortune 500 companies to his own start-up facility service companies in Des Moines, Iowa.

The parent company of Science- Proven Microbial Control®, The Heritage Group was established in December of 2011. It quickly became a dominant force not only for traditional building maintenance and custodial staffing, but also by being the first company in the nation to integrate Science-Proven Healthy Cleaning® into its core offerings. This, along with strategic staffing and reengineering of industry best practices has fueled explosive growth for The Heritage Group and its companies, finding themselves recognized by INC. 5000 for four consecutive years.
