Highlights
Today was awesome. I got to catch-up with an old, close friend from industry (and coincidentally, one of our best customers).
Ryan Baden and team Martinus just keep changing the paradigm in rail. They’re on the way to being the largest self-perform rail contractor globally. Launching in yet another market, watch them scale in the US.
Ryan Baden and I go way back to Glenfield Junction days. 10 years plus.
I remember when he told me that he and Toby Briggs were joining Treaven Martinus to “spin up the infrastructure arm” of Martinus. What a journey.
Watching the team do that from a distance over the past 10 years as well as being privileged to play a small part in the Martinus scale up has been humbling.
Excited to see Denver as the US HQ and to see you guys conquer North America!

I love opening day, not only does it feel like the start of summer, but we get to tailgate with AGC Colorado and members. Great to catchup in person with the OE Construction Corp. crew and our industry people and customers!
