Dr. Kathryn O'Brien-Groom
Medical Director
University of Missouri College of Veterinary Medicine
Dr. O’Brien-Groom’s first job out of school was at a private practice ER/specialty center in St. Louis. She has remained in emergency medicine since that time, with 7 years of teaching/academia and a few years in general practice sprinkled in. She joined VEG in August 2023, and is passionate about their mission of helping people and their pets when they need it most, in addition to providing patients with high quality medical care.
Sometimes it’s obvious when your pet needs immediate help. But sometimes they just seem “off.” That’s where our emergency vets in Brentwood come in. From vomiting to complex surgeries, we treat emergency and urgent care needs for all kinds of pets—even avians and exotics! Discover the VEG difference, with our open floor plan hospitals, pet-parent participation, and an emergency-focused team that’s always ready to expect the unexpected.
Our Brentwood, MO pet emergency hospital is located just west of St. Louis, within minutes of Chesterfield, Hazelwood, and University City. VEG Brentwood, in Brentwood Square, is accessible from Kenilworth Dr., off S. Brentwood Blvd.
Parking for our Brentwood pet hospital is convenient, with a large lot and an accessible parking space near our front door. If you need assistance getting your pet into the hospital, call ahead—one of our VEGgies will meet you at the door. Your pet will receive urgent vet care and you never have to leave their side.
