Lauren Marchell

My dream has always been to work with animals! I began working as a groomer at an animal hospital in 2004. One year later I was trained as a veterinary technician. In 2009 I attended Gwinnett Technical College where I became a Registered Veterinary Technician and received an Associate’s degree in Applied Science in Veterinary Technology. I love working with animals and being their advocate. I am thankful to have my dream job.

I live in Cumming, Georgia with my soon to be husband, Jason. We have a daughter named Avery and four dogs; a Shepherd/Husky mix, Yoshi and three long haired Dachshunds, Camie, Doc and Evie. As a hobby I enjoy showing in AKC conformation events with my Dachshunds,  spending time with family and friends, and hanging out at the lake or pool.
