Our Staff


Dr. Brent E. Herrin - Veterinarian

Dr. Herrin was raised in Cassville, Missouri and received a Bachelor’s of Agriculture and Doctorate of Veterinary Medicine from the University of Missouri in 1988 and 1992. After spending 2 years in north central Indiana in a busy 3 doctor mixed animal practice he moved back to Cassville where he opened the Herrin Animal Hospital. In 2001 he purchased the Monett Veterinary Hospital and received AAHA certification for both hospitals.

Dr. Herrin has a special interest in orthopedic surgery and animal behavior, but enjoys all aspects of small animal practice. He continues to expand the referral services that the hospital provides to other local veterinarians and he is an ELITE product specialist for Zoetis Animal Health.

He resides between Cassville and Monett with his wife, Cordelia, son Eli and daughter Isabel. His family also includes Gus, a Chesapeake Bay Retriever, and Huck, a "stow-away" tuxedo kitty. He is an avid outdoorsman and enjoys hunting, fishing and working on his small beef farm.


Sara Crass - Veterinary Assistant

Sara joined our team in October 2011 and as our clients know, she helps out in all capacities. She spent the first few years with us as a receptionist. As she fell in love with veterinary medicine and became more hands on as a veterinary assistant, she decided to go back to school to become a veterinary technician.

She grew up in northern Iowa and moved to Cassville a few years later to be near family. She stays busy at home with two boys, Parker and Seann, and two step-daughters Reagan and Addison. Sara enjoys attempting to garden with Amara, the family’s German Shepherd. Sara has a talent for comforting our furry patients and their human parents as well!

Erin Crase - Client Care Specialist

Erin came aboard in January of 2015 as a kennel technician and has worked her way to the front desk.

A Cassville native, Erin met her husband, Joe, in 2005. Erin’s large family consists of 4 children, Joey, Kasidie, Katlyn and Jared as well as one grandson, Ian. In addition she has a large furry family, Baby a Chihuahua, Opie a Beagle, Buckshot a Pitbull Terrier and two cats, Honkey and Shadow. Erin doesn’t have trouble filling her time with that crowd but if the weather is nice she likes to be outside fishing, hiking or swimming.

Erin’s warm smiling face will most likely be the one that greets you at the door!

Jori Dodson - Veterinary Assistant

Jori joined our hospital in 2015. She graduated from Verona high school and resides in Shell Knob with her boyfriend and mixed breed dog, Yogi. Jori loves to be on the lake so that is where you will find her in the summer unless she’s at work.
