with John P.!
For John, Mondays are about more than starting a new week. It’s motivating to be part of an organization where people genuinely care about each other’s success and well-being. At Johnstone, it’s not just a place to work, it’s a place where growth, support, and meaningful connections make an impact both inside and outside of work.

Johnstone Supply’s Technical Support and Sales team members, alongside customers, took an in-depth look at the Velocity product line, including product selection, troubleshooting, and the Pat Connect tool. The hands-on training and time spent with Velocity reps made for a valuable experience.
Great products. Great people. Great partnerships.

with Rashon!
For Rashon, Mondays are about more than just getting the week started, they’re about being part of a team that feels like family. From learning more about the HVAC industry to growing both personally and professionally, every day brings something new. And when you enjoy the people you work with, Mondays don’t feel so bad. 💚💙
