Towns like Williston, Stanley, and Tioga have grown substantially due to the oil impact.
But even towns that are not in the heart of oil country have grown.
In this week's Eye on Health, Carla Burbidge tells us about the changes that are underway at St. Andrew's Health Center in Bottineau.
St. Andrews Health Center has been serving patients in this Bottineau region for 100 years.
This is a 25 bed hospital, employing around 100 people.
Starting about three years ago, they began noticing more and more emergency room cases, an increase of 33-percent.
(Jodi Atkinson, President) "Our utilization for the emergency room was about 1,200, and now we're up to about 1,800 to 1,850 in a year's time."
St. Andrews is now in the midst of an expansion project.
The knocked out a wall, and making a larger emergency room.
(Jodi Atkinson, President) "So I am standing in the existing emergency room that had two beds. We've taken out a wall here and we'll be expanding into what was the chapel and we'll be adding two more beds as well as housing a physician office and a handicap accessible bathroom."
For now, emergency room patients are treated in a different area, but this new project should be finished around the middle of March.
Of course any expansion takes money.
They have raised much of it, but a capitol campaign is underway.
