Build a stronger business. Develop the people who can help you lead it.
Core Profit Builders helps residential cleaning company owners turn their goals into a business that works better: clearer priorities, stronger managers, more capable leaders, and consistent follow-through. Our Circles bring practical coaching to the people doing the work.


Built by someone who understands the work.
Liz Trotter has been a part owner in six cleaning companies. As the founder of Core Profit Builders, she combines experience inside cleaning businesses with practical business strategy, leadership development, and the behavioral skills that help people put what they know into practice.
Knowing what to do is one challenge. Building the habits, judgment, and team capability to do it consistently is another. CPB brings those pieces together through the Align Operating System and ongoing coaching and Circles.
Support for the owner and the people around them
A company becomes less dependent on its owner when other people can take responsibility and perform well. That is why CPB works with owners, managers, senior leaders, and salespeople.

In their words
We worked with Liz Trotter to solve our messiest problems. It wasn't easy, but in practically no time our businesses were growing faster than we thought possible. Now I have a full management staff, and faith that my business would be 100% self-sufficient without me.
It's official! One Organized Mom has moved into the ONE MILLION DOLLAR CLUB. We got there a lot faster with your guidance. Now on to $2M!
Since we last saw each other at the end of Foundations in March 2024, so much has changed… Our weekly income has increased by 26%. Our payroll has decreased by 21%. Our call-outs have dropped 49%. … Simply put, Liz — I owe so much of my quality of life today to you.
Meet the people supporting your next step.
