Cheryl Zengler
Managing DVM

I was born and raised in New Braunfels, TX. I moved to Alpine, TX for undergrad at Sul Ross State University. Then, I spent 2 years in Midland, TX to become a Registered Veterinary Technician. Then I went to Texas A&M for Vet School. Finally, I came back home to family and my church and have been here ever since. I am now the Managing Veterinarian at O’Connor Road. I have 2 dogs, Willow Sr. and Jager. Willow Sr. is a black lab mix who is very sweet and patient with the kids. Jager is a chocolate lab who is a perpetual teenager and a lot of fun.. Time outside of work is devoted to my kids and husband. If there is ever any down time I enjoy jigsaw puzzles, counted cross stich, and reading books.
