Founded in January 1990 by Oliver Ibeh, Bio-Janitorial Service, Inc. was built on the belief that “with hard work, anyone can achieve the American Dream.” ​ Mr. Ibeh, who worked various odd jobs while in college, earned a B.S. ​ degree in Management but initially struggled to find better opportunities. ​ After researching the janitorial industry, he started the business with a $200 investment in equipment and supplies, working as both janitor and salesperson. ​ Early revenues of $1,000 per month came from subcontracting work in Phoenix, Arizona. ​

In 1990, Mr. ​ Ibeh began pursuing direct contracts, securing his first with Superlite Block of Phoenix, Arizona, followed by Williams Detroit Diesel in 1991. ​ By hiring its first employee and expanding into medical facilities, high-tech buildings, and manufacturing plants between 1992 and 1995, BJS grew steadily. ​ In June 1993, the company became a corporation in Arizona and was recognized as one of the top 25 janitorial firms by The Business Journal. ​ Mr. Ibeh introduced a unique Quality Assurance Program based on site-specific specifications, honesty, and integrity to deliver cost-effective services and safe working environments. ​

In 1996, BJS secured its first major contract with Motorola (now General Dynamics), growing to 50 employees and achieving annual revenues of $800,000. ​ To meet contract requirements and address employee turnover, the company implemented an EEO/Affirmative Action Program, a Safety Program, background checks, and drug testing. ​ BJS also began offering competitive wages and comprehensive employee benefits, including health insurance, paid vacations, and a 401(k) retirement plan. ​ By 1997, the company acquired several prominent clients, further increasing its workforce and revenues. ​ BIO sucessfully maintains moderate growth while continuing to provide exceptional service to its clients. ​
