ABout the farm

our Family

Mark and Heather were married in 2000 and soon after Heather began direct marketing their red and black angus 1/4, 1/2’s and whole beef to friends, family and customers around the valley.  We also have another full-time business:  Mark Siderius Construction and Excavation.  Mark and Heather have 4 children.  Zachary, Grayce, Lauryn and Beau.  All have been heavily involved in 4H and FFA.  Grayce is currently studying Animal Science at MSU in Bozeman.  Grayce, Lauryn and Beau are all actively involved in our family farm, from having their own registered red angus herd to baling and hauling hay to bringing in the crops to the bins.  So, our 5th generation and beyond will be ready to continue the Siderius legacy.

“Siderius Beef.” The best in the Flathead Valley! Absolutely melts in your mouth.  We are so spoiled, can’t eat anything else. 

Mike & KayLynn Waddell

As third generation Montana land owners, we know the value and importance buying local and supporting area farmers.  Siderius beef is high quality meat, grown locally by a multi-generational family dedicated to preserving farming and ranching in Montana.  We have proudly served Siderius beef at our table for five years now.  It is THE best! 

Paul & Sabrina Dewitt

You have provided our family with high quality, reliable, local beef for five years now!  Thank you for the hard work you do and the quality of beef you raise! 

Sarah & Travis Lynch

When I was growing up my dad bought our family local grown beef from the county fair, and it’s amazing we have access to purchase local-grown, delicious, high quality beef from Siderius Family Farms.  We have bought a half beef each year for about ten years now, and don’t plan on ever not buying it.  It stocks us up for the year and it’s always amazing.  We rarely order steaks when we go out, because we have the best steaks right in our freezer!

We are proud supporters of:

Today this legacy can be felt throughout not only the quality of products being produced by Siderius Family Farms, LLC, but also in the many community agricultural projects, board seats, 4-H and FFA involvement. We are excited to be founding members of Glacier Processing Co-op and to be on the board and planning committee.
