  • Michael Maris, DVM

    I graduated from the College of Veterinary Medicine at Texas A&M University in August 1973. I started practicing at Shelley Drive Animal Clinic on August 15, 1973, joining Dr. Arnold at the time. Away from the clinic, I enjoy fishing and I am the president of the Lone Star Fly Fishers.

  • Kathy Carlson, DVM

    As a kid growing up in rural Kansas, I always had an assortment of livestock and pets, all much to my mother's dismay. I started working in a local veterinary practice when I was 17 and have worked in one ever since. After graduating from Kansas State University in 1984, I followed my husband, Dr. Jon Carlson, to Texas and was very fortunate to be able to come to work in Tyler with Dr. Arnold and Dr. Maris in February of 1986, where I have stayed and been able to develop my special interest in feline medicine.

  • Lizzie Maker
    Veterinary Technician

    I was in the Career and Technology Center Veterinary Technician Program. That is how I got introduced to the Shelley Drive Animal Clinic family. I started as a shadow student for a few months during the school year. As summer was approaching I was offered a position to be a technician. Ever since then I have loved working with this amazing group of people that I call family!

  • Jessica Casebeer
    Kennel Manager

    I joined the Shelley Drive family in November of 2018 as the kennel manager.  I have thoroughly enjoyed getting to know the team as well as getting to know your sweet fur babies.

    Though I'm new to Shelley Drive, I am by no means a stranger to animals or vet medicine.  I started working at my first veterinary clinic when I was 16 years old.  In 2014, I began working at the Tyler Animal Emergency Clinic as a technician and still work there part time.

    I have lived in the east Texas area all my life and plan on staying here for many years to come.  In my spare time I love going to the movies, hanging out with family and friends, watching football, and loving on my 3 dogs and kitty.  I also love to travel for mission trips and spending time with my sweet fianc√©.
