Our Story
Four decades of CEMS expertise, built on a foundation of hands-on service and long-term customer relationships.
The CEMSource Journey
The Beginning
Bob Bohlken, after working in the Teledyne Monitor Labs service department, founded the Continuous Emissions Monitoring service group at Campbell-Sevey. From day one, the focus was simple: show up, diagnose accurately, and fix it right.
Building the Team
Jason Sammon joined in 2007, bringing field service expertise and a commitment to customer satisfaction. Rory Eiynck came aboard in 2011, adding sales and technical depth. Steve Edson joined in 2017, rounding out the team with operational leadership and hands-on CEMS experience.
CEMSource is Born
The CEMS service group spun off from Campbell-Sevey to become CEMSource, an independent, employee-owned company. This transition allowed the team to focus exclusively on what they do best: CEMS and DAHS sales, service, and support.
Factory-Authorized CEMS Specialists
CEMSource is the only factory-authorized field service provider, distributor, and RegPerfect software partner in the U.S. outside of the Teledyne Monitor Labs factory. The team supports all CEMS and DAHS makes nationwide, backed by decades of combined industry experience.
What Employee Ownership Means
CEMSource is owned and operated by the people who answer the phone, show up at your site, and troubleshoot your systems. This structure creates direct accountability and long-term thinking.
When you call CEMSource, you're talking to someone with a personal stake in the quality of the work and in the relationships we build with customers.
Continuity and Commitment
Employee ownership also means continuity. Our team members have been working together for years, and we plan to be here for years to come. We're not flipping the company or chasing quarterly targets. We're building a sustainable business around excellent service.
That stability benefits you: consistent points of contact, institutional knowledge of your systems, and a partner who understands your facility's history and needs.
