Alex Thomson - Stallion Manager

joined SDP Buffalo Ranch in the spring of 2023 and immediately became an asset. She came with a lifetime of horse experience and picked up reproduction and stallion managing quickly. Her attention to detail is incredible and with that, she will assist in sale prepping the yearlings in the off season and with media management. 

Alex was born and raised in Fort Worth and has a background in barrel racing, competing and winning at a high level. With that background, she handled the fast paced breeding season with ease and excels at every task that is thrown her way. And it's obvious that every horse loves her!

Raelyn Verburg - Mare Manager

joined SDP Buffalo Ranch in January of 2024 and is now following her lifelong dream of being in the equine reproductive business. Growing up in the Pacific Northwest, Raelyn has a strong background in ranching and animal welfare. Her passion for horses runs deep and she is committed to ensuring the health and wellbeing of every animal on the ranch. She has competed in a variety of rodeo events and shown reining horses. 

Her profound love for the cutting horse industry stems from her father’s training operation. Hands-on experience in all aspects of a training operation steered Raelyn’s passion towards the elements that create the perfect horse. Even with the extensive knowledge in multiple disciplines, she wanted to be in the heart of the cutting horse country. Moving to Texas in summer of 2023, it didn’t take long to find SDP Buffalo ranch and become a member of this elite team. Raelyn wishes to continue her education in equine reproduction and provide only the best for all of our customers here at SDP Buffalo Ranch.
