Leadership Purpose

“40 years ago, I started my career as a CPA, and I had a vision. I wanted to use my knowledge, skills and tenacious drive to build a better community. I realized I could not do this alone.

25 years ago, I bought one of my clients, Professional Maintenance Systems. At that time we were a San Diego homegrown company with a reputation for quality. Today we clean all types of buildings from San Diego to Seattle while maintaining our reputation for quality.

Most importantly, we have built a pathway to community philanthropy. We see firsthand the direct impact we have on our community, and we see the greater impact that we have by sharing what we do, collaborating to solve problems, and teaching others how to better allocate resources to where they are most effective.

Today my sons work alongside me. They are as deeply committed to bettering our community as I am. Our job is to clean your business, but our purpose is to leave our world a better place than we found it. I am so proud of our whole company and the legacy we are building.

Thank you to all our current and future clients. You make this possible.”

Karen Berry, CEO Professional Maintenance Systems
