Samantha Rebolledo -Veterinary Technician

Hey there! I’m Samantha, a registered veterinary technician who’s been part of the vet world since 2019. I’ve spent my career in general practice, where every day brings new paws, personalities, and challenges—and I wouldn’t have it any other way.

In 2022, I had the incredible opportunity to work in Arizona as a lead surgery tech, and that experience completely ignited my passion for the surgical side of vet med. There’s just something about being in the OR, hands-on and heart in it, that feels like home.

Whether I’m monitoring anesthesia, prepping patients, or assisting with procedures, I’m all about giving animals the care they deserve and supporting the team that makes it all happen.
