DAWN ARMSTRONG, FEEDLOT FIELD SERVICES ASSISTANT was born and raised on a cow calf farm west of Cremona Alberta. Dawn, husband Kent and their two daughters Nicole and Emily purchased her grandfather’s farm in 2003 not far down the road from where she was raised. Their kids are 5th generation on the family farm. Dawn took on some of her mother’s purebred Limousin that she was raised with. With some additions since made by Kent and the girls, it’s become a colourful herd. Dawn has come to appreciate all the knowledge she has learned with the genetics in each breed. Bayler, her Border collie shepherd X , has become her right hand man in the corrals. This made her farm life a whole lot easier with her family gone. With both her kids being academic, athletic and outdoorsy they kept her very busy until graduation when she reached out to VAHS August 2022 to fill in her time. Dawn's passion for cattle, thrill in science and pride in Alberta beef has brought her to the clinic. She’s very excited to be a part of a group that specializes and prides themselves in herd health from cow calf operations to feedlot industries. When she’s not hard at work you will find her roaming through her cows with a comb, under a waterfall with a camera, creating something new in the kitchen or with her feet up laughing with family and friends
