Dr. Florez always wanted to own his own practice, and he had the opportunity to reach that goal when the previous owner of Aztec Animal Hospital offered him to buy his practice. Now Dr. Florez has been at Aztec Animal Hospital since July 2001. In November 2015 he was given the opportunity to purchase Quartz Mountain Animal Hospital and became the proud owner of a second practice.
