Tiffany has been at Katz & Dogs Animal Hospital since 2013. She began her career at Katz & Dogs Animal Hospital as a Care Coordinator at the front desk and has also filled the role of Veterinary Assistant. Tiffany has so many positive traits that it is impossible to list them all, but we particularly appreciate her thoroughness, organization and openness to learning. These impressive characteristics are what earned her the position of Assistant Hospital Director in 2018, and the position of Director of Hospital Services a short time after, in 2020. In her new role, Tiffany continues to wow us with her extensive knowledge about many areas of the hospital, her ability to succeed no matter the task, and her unending support for her fellow team members.


Tiffany wants people to know that, “my favorite part of this job is developing and fostering relationships with all the patients and their families. I enjoy helping people and especially their fuzzy friends.” Unsurprisingly, Tiffany carries on these pleasures in her spare time by helping to facilitate adoptions at the Clifton Animal Shelter. She shares her home with three cats: Ebony, a strikingly beautiful Tuxedo, Aurora, a fabulous and feisty orange and brown Tabby, and Bear, a loving and fluffy Maine Coon mix. Tiffany also recently welcomed her sister, Brie- a frenzied Frenchie- into her furry family. Daisy, her beautiful, calico angel will surely live forever in her heart.

Sargent Pepper

Hospital Mascot, Greeter, Spirit Lifter and Friend to All

Katz & Dogs Animal Hospital has a very important team member who, hands down, is everyone’s favorite! Sarge is Dr. Katz’s and her husband, Matthew’s handsome, yellow Labrador Retriever Mix.

Sarge takes all of his many jobs at the hospital very seriously. He is always there to lend a paw if you have a rough day and he enthusiastically greets everyone who comes by.

On the occasional day he chooses to “work from home” if we had a nickel for every time we hear “Where’s Sarge?” we would be millionaires.

Truth be told, if you ask any of the Katz & Dogs team members they will tell you that he never, ever fails to brighten their day!

He waits patiently everyday for his very favorite mail carriers and delivery people, who always treat him to a special snack. Sarge truly looks forward to their visits.

Sarge happily shares his home with his brother Clarence Lemmons, a striking gray and white feline and his little sister Baby Ruth Ginsburg, a beautiful brown tabby.
