About KSK

Who We Are
We’re a traffic safety and control company — flagging vehicles, setting up safety zones, and making sure everyone from the jobsite team to the woman walking her dog down the sidewalk is safe.
At Knudsen Safety Kontrols, we are committed to running our traffic control jobs with integrity, reliability, and transparency. It’s our philosophy both in business and in life. We’re a family-owned company, and we treat our team — and clients — like family. That’s why it’s so important for us to communicate clearly and honestly, make sure we’re showing up when and where we say we will, and providing the best possible service to you and the community.
We’ve got over 20 combined years of experience in traffic management, and we’re looking forward to providing many more years of support to job crews throughout Ohio.

The KSK Difference

Leading With Integrity
We believe doing the right thing matters — even when no one is watching. KSK is always about honest work and straight answers. If there’s a better, safer, or more cost-effective way to do something, we’ll tell you.

Commitment to Growth
Road safety standards evolve — and so do we. Our teams are always learning and staying on top of best practices.
We’re also committed to giving our employees a clear path to success — providing additional training opportunities for career growth and letting our team grow into the role they’re meant to play.

Body Cameras Provide Extra Accountability
Ready When You Need Us — 24/7
Emergencies don’t wait for business hours, and neither do we. Our crews are on call and ready to respond whenever you need us.
If you are in need of emergency support, please call us directly at (440) 870-5066 24/7.


We Give People a Fair Shot
One of the most important differentiators about KSK is our dedication to making sure everyone has an opportunity for a job. This means providing employment options for underrepresented demographics like veterans and people with disabilities — giving people a chance to show what they’re made of when other employers might pass them by.
