What our Customers are Saying

Average Rating: 4.8 stars (based on 11 ratings)

Phenomenal correspondence, deployment, and execution on-site. Mickey Switzer is my point of contact for my site’s needs and is extremely helpful with making arrangements even when given short-notice. The two folks that came out (Adam Dobrenz and Clint Wurth) were incredibly fast, precise, and professional with handling the absurd number of items they were tasked with completing. Very knowledgeable folks. Fantastic job.

Adam Dobrenz was very professional and courteous. He had a great attitude!

I’m new to the calibration control role. Clint and Adam walked me through how they normally do things here (since they’ve been here before) and they were in and out quickly minimizing our production downtime. Outstanding work!, it is very much appreciated.

Did you know... the precision measurement group at Cross was founded in 1939 by our current CEO's grandfather, Jim King. That's a whole lot of calibration!
Did you know... A fingerprint weighs about 50 micrograms. We know, we weighed it! The residue left from a finger can actually make a difference in weight results which is why we wear gloves when we calibrate weights. For reference, a sheet to paper is about 4.5 grams, that’s 4.5 million micrograms.
Did you know… Cross Company is an ESOP (Employee Stock Ownership Plan). Our ESOP started in 1979 and as of 2006, we are a 100% employee owned! Learn more about our ESOP and how that benefits both team members and our customers.
Did you know… Cross Company has grown significantly since our start in 1954. Over the years we've acquired 26 companies! Today, our five groups have expertise in everything from industrial automation to precision measurement, and industry knowledge going all the way back to 1939.
