Kent Smith


Hi, I am Kent Smith owner and president of Diamond Tool and Engineering Inc.
One of the best parts about Diamond Tool is seeing how much the company, people, and I have grown and developed in nearly 25 years of business. We have built our business to focus on providing excellent service, timing, and quality, for our customers and to be a partner in helping customers maximizes profits. My best days are seeing customer concerns and problems being met by our employees and the satisfaction it brings to all of us.
I was born in central Minnesota at the Staples Hospital where both my mother and grandmother worked at as nurses. My first five years of grade school were spent in a one room building with grades one thru sixth with only one teacher. Afterwards, I attend Bertha- Hewitt High School and Staples Technical Collage for Machine Trades and Mold Building. I always enjoyed shop classes and math through school.
I enjoy trying many different sports and hobbies like fishing, snowmobiling, skiing, hunting and some traveling. I have always enjoyed the outdoors and the many seasons here in central Minnesota. I am married to Dorothy. Together we have five children and three grandchildren.
I have always enjoyed the challenges of family life, business, and where in God’s plan my place is.


Dorothy Smith

Office Manager

Well, what can I say?
I am married to the owner. It is great!
Kent is a man of integrity, honesty and commitment with strong family values. Which is what Diamond Tool and Engineering is built on.
I started working at Diamond Tool and Engineering fifteen years ago. I am now in charge of all administration functions, human resources and IT. I love spending time with family & friends, gardening, cooking, traveling to new places, and helping out at our church. I like all seasons in Minnesota other than winter! (It is just too cold.)
It is wonderful to be working in a team atmosphere. One of the employees was diagnosed with cancer. Everyone chipped in vacations hours, so he wouldn’t go without a paycheck until the long-term disability insurance kicked in. I had to tell the employees we had enough hours to get him through the waiting period.
What a great group to work with!
I am delighted that our culture is to support our customers like we do our employees.


Bryan Amiot

Engineering Manager

WOW, things changed since I started at Diamond Tool & Engineering. I can remember building tools on the bench. We use manual machines and basic 2-D sketches on a drafting table using a triangle and a T-square. I joined Diamond Tool & Engineering in 1991 almost immediately after graduating from Staples Technical College’s Machine Trades program.
I started with Diamond Tool & Engineering as a toolmaker, building molds on the bench. Quickly I moved into programming using MasterCam. From my experience and values I am well equipped to focus on sales and managing customer projects.
I love the challenges of solving technical problems, working with customers, and working with the design team at Diamond Tool and Engineering, and every once in a while, Kent will let me design a mold (just to keep my skills sharp).
I was born and raised in Thief River Falls, Minnesota (way-up North). I have a strong family background where church is important. I married my high school sweetheart and have three awesome kids (they’ll tell you they are young adults). After work I enjoy hunting, fishing, snowmobiles, and any sport with an engine attached to it.
