About Us

I have lived my whole life in the Saint Louis area. I attended Incarnate Word Academy for high school and then headed off to Mizzou. I spent 2002-2006 earning my bachelors degree in Biology before continuing to The University of Missouri College of Veterinary Medicine from 2006-2010. My first 7 years were spent learning clinical and surgical skills in a small animal practice in Chesterfield. My interests include surgery, ultrasound, and internal medicine.

I met my husband in grade school. We began dating sophomore year of high school and have been together ever since. We have been blessed with a marriage of 9 years and 18-month-old triplets who keep our lives very busy! Our household is rounded out by a 10-year-old Australian Shepherd named Brewer.

Hi! I’m Kate Callaway, DVM. I graduated from the University of Missouri College of Veterinary Medicine in 2009. I am originally from Kansas City, but moved to St. Peters with my husband, Kyle, after graduation. Together we have two kids, Declan and Teagan, as well as two dogs, Dublin and Kimbo. I knew at a young age I wanted to be a veterinarian. My parents were very encouraging, even when that meant stopping the car for the hundredth time so I could move another turtle out of the road.

After graduation, I practiced emergency medicine for 4 years before switching focus to small animal general practice and I am very excited to now be a part of The Pet Doctor! I truly enjoy building relationships with clients and their animals. I have a special interest in emergency and critical care medicine as well as diagnostic imaging. I am a member of the American Veterinary Medical Association, the Missouri Veterinary Medical Association, and the Greater St. Louis Veterinary Association.

Animals, like humans, can have headaches, jaw pain, mid and lower back pain, constipation, and problems with their limbs.

Dr. Alyssa Brahler is an Associate Veterinarian at The Pet Doctor. After graduating from Alton High School in 2014, Dr. Brahler went on to receive her Associates Degree of Science in 2015 from Lewis and Clark Community College, her Bachelor of Science in Biomedical Sciences in 2017 from Southern Illinois University Edwardsville, and finally her Doctor of Veterinary Medicine in 2022 from the University of Missouri College of Veterinary Medicine. Her professional interests lie in dermatology and animal behavior.

Dr. Brahler began her veterinary career back in 2012 where she began shadowing and volunteering with animals. Throughout her education, she had the opportunity to travel to Ukraine to clinically train with the ‘Clean Futures Fund- Dogs of Chernobyl.’ Back home, she also had the opportunity to work with the Humane Society of Missouri and held an Animal Medicine Center Internship. Dr. Brahler explains her inspiration to work in the veterinary field came from her time volunteering at her local equestrian center in high school. There, she assisted in the training sessions for those with developmental disabilities and was able to witness the strong bond between human and animal. To this day, her favorite thing in veterinary medicine is being a patient advocate and helping maintain the animal-human bond.

Having grown up in Illinois, Dr. Brahler now resides in Columbia, Missouri with her fiancé Derek and her two pups; 5 year old Snoop, a deaf blood hound mix, and 9 month old Pepper, an energetic pit-lab mix! While Dr. Brahler and her fiancé are busy planning for their upcoming wedding, they enjoy being outdoors, cooking, and playing board games in their free time. Dr. Brahler truly cares about each creature as she explains her childhood pet was a turtle she named “Mr. Speedy-Quick” because she did not want him to feel self-conscious about his speed!
