Bullpen & Diamond T Cowhourses

The Thorlakson Stamp

More than a business.

Our passion and experience in the sport of team penning and ranch sorting is something that sets us apart from other arenas. We hold regular practices along with a variety of clinics to give riders an opportunity to improve their skills in this exciting sport.


Facilities include:

Indoor arena: 80 feet by 220 feet

Outdoor arena 105 feet by 250 feet

Annex for horse tie ups and stalls




The Bullpen was originally built to provide an indoor sales area for our bull test station, hence THE BULLPEN. In 2010, the interior arena was expanded to accommodate a team cattle penning arena after Ben, Tom, and Lindsey fell in love with the sport. Since then, we have become a staple for Central Alberta Team Penning Association, Chinook Team Penning Association, Ranch Sorting National Championships, Alberta Team Sorting Association, Alberta Ranch Horse Versatility Association, Alberta Barrel Racing Association, and 4H Clubs.

Diamond T Cowhorses

Tom Thorlakson, owner of Diamond T is an accomplished horseman with a passion for horses and the sport of team penning and ranch sorting. His most recent accomplishments include the 2016 and 2017 Calgary Stampede Open Class Team Penning Champion.

Finding the right horse is often tedious and frustrating. Tom will take the time to match horse and rider to complement each other. If we do not have the perfect match in the barn we will assist you in the search. Getting you and your new horse rapidly into the show ring and the winner’s circle is my goal.

Diamond T will be your one stop shop when looking for an upgrade. Everything from beginner to open caliber penning and sorting horses are on hand at all times. We also have cutting, roping and barrel racing prospects in the barn ready for their future with you.
