Dr. Kronewetter comes to us by way of El Paso, Texas. She attended Texas A&I University in Kingsville and earned a Bachelors Degree in Animal Science. While working on her Masters degree, she was accepted into Auburn University School of Veterinary Medicine, "War Eagle!" Her original plans with her DVM degree was to enter the field of animal research, but fate pushed her into general practice. She has worked all over this state as a practitioner and relief work. She loves general surgery especially cosmetic and soft tissue cases, dentistry and feline medicine. When not a War King, she is an avid DIY'er, a wood worker, an amateur chef and a beginner wine connoisseur. She has 2 pugs, Gracie and Bobi, and a Bengal-mix cat named Lily.

Dr. Maria Hey grew up in Amarillo, Texas where her love of animals began. She then headed off to College Station, where she earned her bachelors degree in biochemistry and her DVM from the Texas A&M College of Veterinary Medicine. It is there where she met her husband, Dr. Pete Hey. They were married in 1991, just a few months before her graduation. They now have three beautiful children, Gabriel, Malachi, and Hannah. Dr. Maria Hey also has a passion for photography, as you will quickly notice just by stepping into Deerfield Animal Hospital's doors. In addition to her positions as Practice Manager and Mom, she runs a small part-time photography business, Maria Hey Photography. The Hey family has a number of pets including three cats (Angel, C.C. and KiKi) and three dogs (Scooby, Woody and Cliena). You can meet C.C. or Kiki when you visit Deerfield; they are our infamous "greeters".
