Dr. Katie Smith grew up in Boulder, Colorado. After graduation from Boulder High School, Katie attended the University of California at Santa Cruz to study Marine Biology. In 2000, after some soul searching, she returned to Colorado to continue her education with a focus on physiology and medicine. Katie enrolled in the Animal Sciences Program at Colorado State University and began volunteering at the Veterinary Teaching Hospital. She soon realized she had found her calling in veterinary medicine. Dr. Katie graduated Summa Cum Laude from the Colorado State University School of Veterinary Medicine in 1998. Since then, she has worked at veterinary hospitals in California and Colorado ranging from a ten doctor, 24-hour hospital and surgical referral center, to smaller one and two doctor hospitals. Dr. Katie has always had a strong belief and grounding in Western medicine, but she also recognizes the value of an integrative wellness philosophy. In 2009 she became acupuncture certified through Colorado State University’s Medical Acupuncture for Veterinarians program. Dr. Katie loves practicing all types of veterinary medicine but currently puts a special focus on patients with arthritis and other chronic pain conditions. She uses Western medicine, nutrition, nutraceuticals, acupuncture, low level laser therapy, and massage to maximize patient comfort and quality of life. In her spare time, Dr. Katie enjoys walks, long bike rides with her husband, Mark, and travelling.

"Dr. Vangi is amazing. I have a dog that has severe allergies and ear infections. She is the only vet that has taken the time to examine her thoroughly and give her proper treatment. I’m so grateful to have found such an incredible veterinarian. Thanks, Dr. Vangi and staff."

"I and my Mom and Dad thank you and your staff for all the wonderful care and the help you gave me. My Mom was going in for knee surgery, and my eye problem started about 2 weeks before this, so they had a lot of stress trying to care for me and get ready for Mom’s surgery. I had eye surgery done by Dr. Smith, and the outcome was successful!!!! Thank you all of you.."
