At Mister Kleen our employees are our success! We recognize excellence with our Employee of the Quarter awards. Every quarter the operations management and headquarters management teams nominate and vote for the employees who have made the most meaningful impact on our clients, their co-workers and our company. Winners receive a certificate, a monetary gift, and recognition in The Kleen Sweep!

Nellie Knight

JULY 2021

“Nellie has really stepped up to take the lead lately. Her husband has been out battling lung cancer all year and the supervisor there has been out the last month or so battling their own health issues. She has been driving back and forth two hours each way daily by herself to make sure the crew and Mister Kleen remain successful at this site.”

Craig Dufour, Area Manager


Terry finds a way to miraculously fill challenging high-security openings. Most recently, Dianna communicated the urgency to fill positions in a High Security facility and within two weeks, he found candidates for eight of the nine openings. He is so likable and has such a positive attitude and never in a bad mood, regardless of what is thrown at him! He will do anything to support MK–including making up games for client events and driving across the world to retrieve a badge. Terry is an invaluable member of the team, and we are grateful to have him.”

You Make A Difference Award

Bozoma Arizi

Bozoma Arizi
July 2021

Bozoma Arizi deserves the Employee of the Quarter award because of one word: perseverance. She inherited the difficult task of improving our Central Plant and has done just that. The tenant who resides in the building have nothing but great things to say about her. With an impeccable work ethic, she reminds many of the energizer bunny, always moving. She will tackle any task that is given to her with open arms as has the confidence and cleaning knowledge to get it done. Now more than ever reliable help is needed and Bozoma exceeds in reliability and is extraordinary. Mister Kleen improves as a company each day she clocks in.”

Brandon Caison, Project Manager

Antonio McLean

Antonio McLean
October 2021

“Where do I start with how great of an employee that Antonio McLean is. He is ultra-dependable, courteous, and a down-right hard worker. The tenants absolutely love him, and every time we have an inspection in his areas, they tell us how great he is. His location has received several kudos letters (four to be exact) about Antonio. He takes it all in stride and remains humble. His co-workers adore him, and he provides them with a great laugh daily. If there was an employee of the year award, I would put his name in the running every time. Whoever hired him did this company a great service and we are a better company because of it.”

Nicole Poe, Site Supervisor

Employee Training Update

Mister Kleen is committed to continuous regular training of employees to better serve our clients – which we recognize sets us apart.

We have been busy educating our team members over the last several months with the latest in COVID-19 safety and protection as well as other timely, educational trainings. Below are some of the highlights from recent training events:

Fire Safety and First Aid: This training ensures employees understand fire prevention and procedures in the event of a fire. Basic first aid is also reviewed.

Sexual Harassment: Sexual Harassment training ensures that employees understand the legal definition of sexual harassment, Mister Kleen’s policy, and the complaint reporting process. This training also addresses how to promote a culture of respect and the importance of professional boundaries.

PPE Training: Field employees receive training on the proper use of Personal Protection Equipment (PPE), including when to use it; what PPE is necessary; how to properly put on, use, and take off; how to properly dispose of or disinfect; how to inspect for damage; how to maintain PPE; and the limitations of PPE.

Cold, COVID-19 & Flu Prevention: Employees receive training regarding hygiene, the importance of personal self-care, prevention myths, and treatments for a cold or flu.

Pandemic coverage: Employees are trained in how to maintain a clean and healthy environment to prevent the spread of infectious diseases and viruses.

Security Awareness/Ethics Training: Security awareness training teaches employees how to recognize and report suspicious behavior. Ethics training focuses on how to identify when our own communications styles and behaviors could be perceived by others as harassment or discrimination.
