Employee Training Update

CPR training NEW
Members of the Kleen Team learned CPR at the Alexandria headquarters in May.

Mister Kleen is committed to continuous training of our employees to better serve our clients – which we recognize sets us apart. We have been busy educating our team members to ensure they are up to date with the latest protocols in cleaning for health and appearance through our Enhanced Kleen Program.

Additionally, we offer optional bi-weekly IT training sessions covering frequently requested topics for all employees. We also have an Online Learning Management System (LMS) with over 4,500 courses. Managers are assigned training to improve areas of development like active listening, encouraging team communication and collaboration, setting goals, and leading diversity.

Below are some of the highlights from recent training events:


Employees are trained to recognize and prevent slip, trip, and fall hazards in the workplace. Managers also receive a review of Occupational Safety and Health Administration (OSHA) regulations and post OSHA forms in buildings.


Employees received training for the procedures and proper handling of bloodborne pathogens and other potentially infectious material. Employees were also trained in the procedures for handling trash.


The Kleen Team learned about common workplace hazards for cleaners and safety measures to prevent illness and injury.


This training helps ensure that employees understand the legal definition of sexual harassment, Mister Kleen’s policy, and the complaint reporting process. It also addressed how to promote a culture of respect and the importance of professional boundaries.


All staff received training to ensure that products were being used correctly and ensured that they are Green Seal (GS- 42) compliant.

Human Resources led training for supervisors on preventing workplace injuries and facilitating return to work.

Training for HQ Employees and Managers took place at our Alexandria headquarters.


Staff reviewed training for the safety procedures for lifting.

Human Resources led a webinar and video training for employees who drive Mister Kleen vehicles as well as for those who regularly drive their own vehicles.

Beyond Service User Conference

Mister Kleen is committed to continuous training of our employees to better serve our clients. In January, Controller Warren Oxford and Accountant Madelyn Jackson attended the 2023 Beyond Service User Conference on software solutions for field service industries.

We are proud to have Warren and Madelyn representing Mister Kleen at this national conference where our industry and other peers gather to learn and network!

Team Player Award

The annual Tom Miller Team Player Award honors employees who demonstrate great contributions to the team, positive team interaction, high customer impact, and quality outcomes. Employees are nominated by their supervisor for this award, which is named in honor of beloved former employee Tom Miller. Tom exemplified what it means to be a team player and his eight years of service made a lasting impact on the Kleen Team, our customers, and everyone he touched.

This year’s winner, James Heavener, worked with Tom and looked up to him, according to his supervisor, Kathy Heavener. “Tom really taught him a lot about life and being in the cleaning business. He is a great team player,” she said. “James never misses time unless it is scheduled in advance. He goes above and beyond to make sure the customers and tenants are well taken care of and satisfied. He gets great comments and works well with his team. He is the vacuum tech as well as helps self-monitoring co-workers that are not cleared.”

Congratulations, James, on winning the Tom Miller Team Player Award!
