Stacy Mozisek, DVM

Medical Director

As Medical Director of the Firehouse Animal Center in Westlake, Dr Stacy Mozisek is focused on her clients and patients, as well as leading her team.

When caring for clients and patients, Dr Mozisek is passionate about supporting the human-animal bond with the best treatment plan for the family. As a working mother of three, she understands it can be challenging to implement a medical treatment plan at home. So Dr Mozisek strives to be compassionate and collaborative, working with clients to develop realistic health plans that enhance each pet’s life and improve the human-animal bond.

Dr Mozisek and her team are passionate about providing an exceptional and stress-free visit to Firehouse. She goes above and beyond for her clients, taking extra precautions for pets who struggle with veterinary visits by implementing Fear Free tactics and learning about the pet’s specific needs and triggers. Each pet presents new challenges and joys for Dr Mozisek.

Dr Mozisek is a compassionate and collaborative veterinarian who credits her awesome Aggie veterinary training and extensive work experience for her doctoring style. As Medical Director of Firehouse Westlake, she brings empathy, humility, humor, and a strong work ethic to her team. Since joining Firehouse in 2013, Dr Mozisek has developed strong relationships with her patients and their humans. To her, Firehouse is a place where pet owners feel more like friends and family than clients.

Dr Mozisek regularly participates in local and national veterinary conferences and has been included in an exclusive veterinary round-table discussion about zoonotic pet diseases. Her favorite conference is the AVMA national veterinary conference, which she and her poultry veterinarian husband attend together.

Dr Mozisek is a retired triathlete, lover of all things outdoors (including live music), mother of three kids and Juniper the Labradoodle, a regular patron to Barton Springs pool, and Orange Theory junkie, and a decent yogi. Her bucket list is full, including but not limited to Spanish fluency, mastering the acoustic guitar, and riding her bicycle across the country.

CJ Champ

Hospital Manager

Ever since he was a young child, CJ has always wanted to work with animals. He grew up in northeastern Iowa, and after working for years in retail, he moved to Boulder, Colorado, in 2009, where he landed his first job working with animals. He started as a kennel technician at a “bed and breakfast” for pets and realized he had found his calling.

He visited Austin for the first time in 2010 and moved here with his cat a few months later. He started working as a receptionist at a nearby boarding facility before finding a veterinary hospital on the east side of town. He started there as a kennel technician, then became a receptionist, then perfected his veterinary technician skills before becoming the head veterinary technician.

CJ has been looking forward to joining the Firehouse team since he first stepped into the Davenport Village location in 2014. He was very excited to make the transition over to step in as Hospital Manager for such a fantastic place.

CJ’s veterinary passions include building and developing client relationships, client education, nutrition, pain management, and creating a stress-free environment for clients and patients. He has been in Austin for seven years now and has no intention of leaving! He lives with his partner of four years and their three big dogs (a Labrador/pitbull mix, a German shepherd, and a special needs dalmatian/pitbull mix), a mischievous orange tabby, and an inquisitive Bengal cat. When not spending time managing his tiny zoo, he is usually busy working on his bachelor’s degree in sociology.

John Faught, DVM

Co-Founder, Chief Medical Officer

As co-founder of Firehouse Animal Health Center and a practicing veterinarian, Dr John Faught has a unique perspective on the veterinary world. He merges science-based medicine, empathetic communication, and practical solutions to help pet owners choose the best path for their families and their pets. At the same time, Dr Faught provides leadership for the Firehouse team and steers the hospital toward impeccable service, growth, and philanthropy.

Most clients who visit Firehouse see Dr Faught as a trusted friend, someone who offers medical guidance with patience, warmth, and a sense of humor. Dr Faught looks for this same spirit in his team. Firehouse veterinarians are not only skilled in medicine, but they are also willing to do “100 Little Things” — those extra moments of connection, support, and kindness — to remind clients they’re at the right place for their pet.

Dr Faught learned at an early age that we all play a role in making our communities healthier, safer, and happier. This is why Firehouse gives generously to local animal-support organizations by donating funds, free medical services, time, and ideas. “We are better individuals and a better business because of it,” says Dr Faught. “It brings value and purpose to what we do each and every day.”

Dr Faught is a regular contributor to local and national media, helping to educate the public. He earned a degree in Biomedical Science at Texas A&M University, followed by a doctorate in veterinary medicine from Texas A&M’s esteemed College of Veterinary Medicine in 2004.

Dr Saunders stays current on all aspects of veterinary care through medical journals, national conferences, including the Veterinary Meeting & Expo (VMX) and local veterinary groups. She’s also a member of the American Association of Feline Practitioners (AAFP).

Having worked as a kennel tech in high school and at the Columbus Zoo and Aquarium in college, Dr Saunders grew up knowing she would become a veterinarian.
