Sheldon Van Voast

Say hello to Sheldon Van Voast, Cofounder and CEO of NOS. Sheldon’s a family-man through and through – whether it’s with his 4 kids and 8 grandchildren, or with the NOS crew. His beginnings in the Oilfield sector go waaaay back to 1980, where he scored his first Oilfield job as a scrub hand for Challenger Drilling in North Dakota, followed by a roustabout offshore gig with Transworld Drilling in the Gulf of Mexico (1983). Shortly after in ‘86, Sheldon graduated with a BS in Petroleum Engineering from Montana Tech. Fast-forward to 2017, Sheldon cofounded Northern Oilfield Services LLC, alongside COO, Jimmy Robinson and to this day, he is blown away by the folks at NOS and their incredible ability to problem-solve and “think outside the box.”

Jimmy Robinson, Founder and COO of NOS, Jimmy’s humble beginnings in the oilfield industry (over 19 years ago) had him cleaning trucks, painting tools and washing gloves at his fathers company. A big believer in having fun, Jimmy fosters this attitude at NOS and appreciates that “The passion here is amazing all the way down from Ownership to the newest hire. I couldn’t have asked for a better company to be a part of and I am proud that I had a little something to do with how it has turned out.” That’s the kind of COO we all want, isn’t it? When he’s not with his work family, you’ll find him spending time with his lovely wife, Ashley and their two kids, Adrian and Collins.

Meet Jacob Ehlers, Sales Director at NOS (and buffalo-wing aficionado at any restaurant)! Counting over 11 years in the Oilfield industry (woot), Jacob started out as a shop technician at FMC and moved up the ranks in his career moving through the ranks to Operations Management at Downing Wellhead, Completions Consulting for XTO Energy before finally joining the team at NOS. According to Jacob, the best thing about working at NOS is the atmosphere and people. “Everyone here works well as a team and most of them have been working together in some way for the majority of our careers. So we all know each other and work like a family.”… We’re not crying, you are! He lives in Williston ND with his wife, Julie and their 3 children, Kennedy, Sophia and Aiden.

Once Luke B. Lumpkin, NOS’s Corporate Sales Executive starts his day off with his favorite Peanut Butter Protein Smoothie, nothing can stop him from getting those contracts and building those relationships! He was already managing a 24/7 dispatching team (who remotely monitored and dispatched the operating status of hundreds of pump jacks over cellular transceivers) at his very first gig in the industry over 15 years ago. He’s only been with NOS since May 2022 but he’s definitely made an awesome impact with us. Luke immediately knew he was in the right place on his first day with us when he was welcomed aboard and the corporate team introduced themselves as being a bunch of misfits, Ha!

In the 6 ½ years that she was at Weatherford, she trained new AR admins and assisted with the dispatchers as well as service technicians. We’re stoked to have Erica be a part of the NOS team and we think she feels the same because, well… she literally said so: “The people! Everyone that I work with is amazing in their own way. Family-oriented and extremely understanding. Always helpful no matter what the issue at hand is.” Erica’s a mom to 5 awesome children (her oldest is 28, youngest is 9) resides in Williston and LOVES coffee.
