About Us

In 1987, John Post purchased a cable rig and started drilling. He never looked back. Over the three decades since, John built one of the largest drilling companies in the rocky mountains. He has drilled domestic and commercial wells from Arizona to Montana, Oregon to Wyoming. In 2012, he discovered northwest Montana, sold everything and settled in the West Kootanies.

After enjoying a few years of hobby, family time, and traveling, John, decided to come out of retirement to fill a growing demand in Eureka, Kalispell, and surrounding areas for a dependable, expert well driller. Post Pump and Drilling is a family-owned, local hiring company backed by experience and quality service. Scroll down to learn more.

A New Generation of Drillers

In 2024, John and his oldest son, Clint, successfully completed the final stages of passing on the baton. Clint was 5 years old when John started drilling. He spent summers, weekends, and any days off from school helping his dad, uncles, and other team members drill wells and install and service pumps. He has drilled and serviced pumps for over a decade and in 6 western states.

As a second generation well driller and pump technician, Clint is striving to fill the huge shoes left by his father, but grow them for the next generation. He is excited to service the water well needs in NW Montana and surrounding area.

Clint and his team are working under their company name: Alto Well and Pump, LLC. Click Here to learn more about Alto Well and Pump.

These folks have integrity and I trust them completely. The difference between a great business and a mediocre one is how they respond when things don't start out right. In this case, initially, things started out badly. An employee was making it very hard to have our well drilled and this was potentially going to delay the building of our new house. When I contacted John and his wife to complain, he personally looked into the matter, addressed it with the employee, apologized profusely to us, and got to our well drilling job as soon as possible. These folks have a lot of integrity!

Post Pump & Drilling drilled our well ahead of the scheduled date and through the job the drilling rig operator explained just what was goin on including what kind of rock and other substrates the drill head was going through. He was very knowledgeable about the whole operation as well as the geology of the area and happily answered any questions. When John Post came on site again to help with the final stages of the operation there is another level of knowledge and willingness to explain and or answer questions. We really appreciate The whole Post team and there willingness to get our well drilled.Again thank you for your promptness expertise and hard work.D&J

Extremely satisfied with the quality of the work performed. Excellent communication from them throughout the process. I was around for both the drilling and the placement of the pump. No short cuts, delivered on their promises. And they’re nice people too! A great family business.

I was extremely happy with the work that was done for us. Drilled our well and installed all the equipment to my satisfaction. I would recommend these folks to everyone.

I really liked working with Post Drilling. Their knowledge about the ground and how to find water was priceless. We found water right where they said. I have one or two more wells to drill and I’m genuinely excited to work with them again.

They were a great help and walked us through everything, very important to us since we were new to the area.

John, Clint and Josh are dedicated to their craft. I live in Haskill Basin which is notorious for fickle and difficult wells. They went beyond and above to get water to my house. They have integrity and stand by their product. I will use them again and recommend anyone in need of water to use them. They are professional, courteous and fair. 5 stars

Clint and John drilled a well and installed a pump for us. From start to finish they were professional and honest. So much of what goes into to this you can’t see as the property owner but they explained things in a way that made it easy to trust them and you knew they were doing what was best for your water. Any questions I had along the way were promptly answered even after I paid the bill. I wouldn’t hesitate to hire them again if I ever needed it.

Post drilled our well June of 2020, and I couldn’t be happier with them. They’re very responsive, and informative. They spent plenty of time with us before they ever punched the hole, and we felt very comfortable about the whole thing. We weren’t able to be there when they hit water, but they were very communicative and prompt. They’re very trustworthy, honest, and hard working. I recommend Post 100%.

We spoke with several well drillers before we started, and we think we got lucky when we found John and Clint (and Josh) to do our job. They are experienced, very knowledgable, hard working, honest, and pleasant to work with. (John has great stories). We had a tough project at our site, and these guys never let up; They wouldn't quit until they found us good water. I would highly recommend them.

John and the Post Pump & Drilling team are great to work with! They obviously had in mind our success and satisfaction as property owners. They communicated with patience and gave us options at several points as the drilling progressed. We highly recommend them in Lincoln County - or wherever in northwest Montana they're available to go.

Clint and his family did a fantastic job installing a hand pump for our existing well. He also told us a few things to possibly look out for in the future given the age of our pump. We'll definitely be using them again for the old pump replacement. Thanks for the hard work!
