One vet.
Your dog,
your cat,
your cattle, your horse.
Mission Valley Veterinary Clinic is a mixed-practice clinic in Ronan, Montana. Bring the kitten in for shots, then have us drive out to the ranch for herd health. Same vet. Same phone number to call.
The brown, wooden building between Cenex and Don Aadsen Ford.
Look for us at the intersection of Highway 93 and Timberlane Road, at the south end of Ronan. We've been providing animal care in the Mission Valley since 1941 — a mixed-practice clinic with mobile services for the ranches and homesteads spread across the valley.
Our promise is simple: deliver high-quality care to your animals so they can have better lives, and so the people who love them can, too. That's been the job for 85 years and it still is.
Call (406) 676-4251 to set up an appointment, or send us an email. We look forward to meeting you and your animals.
Care for the family pets. Care for the family ranch.
A mixed practice means the cat on your couch and the cattle in your back forty have the same vet on call. Same medical record. Same person picks up when you dial.
Wellness exams, vaccinations, dentistry, surgery, in-house IDEXX bloodwork, digital radiology, ultrasound, allergy testing, parasite control, and end-of-life care — all under one roof.

Dr. Kevin Detwiler has been practicing in Western Montana since 1982 and is the clinic's owner and sole veterinarian. Around him: Debbie (the clinic mom), Nicole at the front desk, Shelby in the back — and a small staff of clinic cats and dogs who consider the waiting room their living room.
