John Miller

Owner/Project Manager

John is a co-founder and project manager for JNL Designs & Construction.  He began his construction career at 15 yrs old in Riverton, when he was hired by a drywall company to clean up.  He worked his way up to a drywall finisher until his family moved to Casper.  Once established in Casper, he got a job with a home builder as a laborer/carpenter.  There he learned framing, roofing, siding, and trim skills while building spec and custom homes.  After a time of building homes, he decided to return to school and pursue an A.A.S. through Casper College. While in college, John worked for friends and family doing small renovations.  In 2009, John graduated with an A.A.S. Fire Science Degree and began pursuing a career as a firefighter.

John and his wife Natalie were married in 2009, at which point John worked for the local Trauma Center, Public Services Communication Center, Mills Fire Department, and a local contractor doing new construction.

In 2013, John was hired by the City of Casper Fire-EMS Department as a firefighter, where he is still employed. 


Construction has always been a passion for John, he loves problem solving building issues.  This passion along with the desire to own his own business, led to the opening of JNL Designs in 2016.  The name was thought up after the birth of John and Natalie's 2nd child, Canaan, was born.  It stands for John, Natalie, and Littles, which was primarily opened with the intent of constructing concrete counter tops and furniture, however, it became evident almost immediately that this company was going to specialize in general construction.

John worked solo for most of the first year of operation.  Due to the work demand, it was decided to bring on a couple part-time guys who were already co-workers (at the firehouse).  These guys were brought on in the spring of 2017 to help catch up...only thing was, the work didn't slow down.  

John has recently moved into a project management position.  This allows him the time to talk with the clients and work with them to ensure their expectations are exceeded.


"For projects of any size, JNL is our go-to. The quality of the work is amazing, in addition to looking fantastic. And, every project I've had done or seen done gets the same level of quality and attention to detail."

"We just had a kitchen counter, sink, faucet and garbage disposal done by John Miller. He was quick to respond to my phone call about an estimate, did the job in record time and it looks great! I do not give praise lightly. In my estimation John and his company are 5 plus stars!!!!"
