24 Hour Emergency Vet Hospital and Urgent Pet Care in Boulder, Colorado
Dr. Lindsey Geiger
Medical Director
University of California; UC Santa Barbara; UC Davis
Dr. Geiger grew up in California and graduated vet school at UC Davis in 2015. Early in her career, she worked as an urgent care vet in Denver and a shelter vet at Humane Colorado. Dr. Geiger has also traveled internationally to perform spay/neuter surgeries and provided preventative care in low-income communities.
A former colleague introduced her to VEG in 2020 to help manage the caseload. She grew to love the VEG model and the high quality of medicine provided. She enjoys keeping people and their pets together every step of the process and finds that it reduces stress for both the pet parent and the pet. She helped open VEG in Edgewater in 2022 and then moved to VEG in Boulder, where she now serves as Medical Director.
Dr. Geiger expresses that she will never go back to doing things the old way and that being a part of VEG is a privilege, as VEG is changing veterinary medicine. The freedom to say “yes” and help people and their pets no matter the circumstances is what she loves most about VEG.
