About Us

Our Story

Rocky Mountain Excavation & Grading LLC was founded by James Simmons based upon his years of experience in the fields of heavy civil engineering, foundational drilling, excavation, grading, demolition and construction services work. Since its inception, RMEG has grown quickly and developed an excellent reputation for quality work, on schedule project completion, and an ability to meet its clients' needs within their budgeted cost.

James grew-up in Rural Pennsylvania before moving to California where the majority of his construction experience was obtained. He started his career out of High School as an apprentice Heavy Equipment Technician with Caterpillar, before getting involved in the construction Industry where he worked for several companies in Northern California before joining Malcolm Drilling Company, Inc. one of the largest deep foundation and drilling contractors in the US. Valuable knowledge was gained here working on the largest construction projects on the West coast. From a young age James always had a passion for hard days work for hard days pay and was drawn to heavy equipment. In his early teens had a very successful lawn-mowing business in rural Pennsylvania. His passion for bigger machines grew, as did his entrepreneurial desire to set-up a business revolving around earth work, so in early 2021 he set-up Rocky Mountain Excavation & Grading.

From the start, RMEG has been successful securing a pipeline of project work which has allowed it to grow and add more equipment, people and experience to its fleet. However, its success is most importantly a direct result of the RMEG Team, and their passion to work hard to meet their clients' needs, AND critically - to get the job done right, the first time!


RMEG is dedicated to meeting a client's every need throughout all phases of their project. Providing the highest quality services to fulfill all expectations of customers, partners and sub-contractors will ensure RMEG's outstanding reputation. Attention to detail in every aspect of a job, has been, and always will be a critical part of the mission!


Christina: (Belgrade - Excavation, Grading & Hauling):

“Excellent service and responsive. James was very accommodating in meeting with me in a timely matter and walking the property prior to the project start date. They worked relentlessly to complete the project with short notice. The end was better than expected. James went above and beyond to complete my project on budget along with leaving my property vastly improved, highly recommend!”

Pete: (Big Sky - Retaining Wall):

“James was very easy to deal with and we had some great conversation. They were very affordable and worked with me to meet my budget. Their work is clean and they have an eye for detail. They went above and beyond our expectations and I have already recommended to many of my friends.”

Tim: (Bozeman - Excavation/Grading with hard access):

“I used Rocky Mountain Excavation recently to grade my backyard for a new patio and trench for the footing of a new retaining wall. the access was difficult, as is often the case. James did a great job, ensured appropriate slope with his laser level, was on time and courteous, helpful with other suggestions for the site and had a fair price. I also used him to move 10 tons of stone i bought for my wall from the street to my yard below, again in a difficult access environment. I would use James again for similar work.”
