Dr. Austin Stitzer

Hospital Owner

Austin Stitzer D.V.M. was born and raised in the suburbs of Philadelphia, Pennsylvania.  He did his undergraduate education at Arizona State University and then moved to Texas to go to Texas A&M University College of Veterinary Medicine.  After graduating in 1999 he moved back to the Valley of the Sun, and worked as an associate Veterinarian in the valley that helped him refine his skills, learn reproductive medicine and other specialties.

 

Dr. Stitzer has been in business since 2003, and ensures that his hospital offers compassionate and friendly service with excellent medicine.  He prides himself on his wonderful staff, and the knowledge and care they offer on a daily basis.  He is amazed with the passion his associate doctors possess, and the great but fair medicine they practice.  Dr. Stitzer became a veterinarian not only for his love of animals but for the personalized bond they create with humans.  He tries to continue this philosophy through his hospital.

 

Dr. Stitzer is blessed with an adorable boy named Chaz who is his entire universe.  He enjoys the outdoors, sports, and is an avid traveler.  He is a die-hard Aggie fan, but will definitely see animals with owners from other conferences.
