I've been a veterinary assistant at Switzer Vet Clinic since July of 2021. I was born and raised in Florida where I groomed, trained and showed dogs professionally around the U.S. I specialized in working breed but was an all breed handler, My biggest accomplishment was being invited to the Westminster dog show in New york City where I was invited for both top junior handler and conformation.  I now have a wonderful English Pointer named Ghost that I hunt small birds with and show him in confirmation all over the state of Michigan. I also trained horses in Ocala Florida and showed in western disciplines and Dressage. I now have 2 horses of my own at my small farm.  Since moving to Michigan, I have taken many interests in the outdoors (Hunting and fishing). I enjoy spending time with my two wonderful children, my husband and my animals. I enjoy working with both large animal and small animal medicine and hope to further my education in the veterinary field.
