About Our Clinic


I couldn't be happier with the care that Mr. Whiskers received. He's doing much better now, thanks. Highly recommended.

Meet Out Team


Warm Friendly Greeting


We will welcome you into our home and treat you like family


Kimmi says her favorite part of her job is the people that she works with every day. She especially loves the clients, and says that they feel like family to her. Kimmi grew up on a farm in Lockport, IL where she took care of her family's goats, horses, dogs, cats, ducks and ferrets. However, now she has limited her collection of pets to two birds and two cats. Skittles, aka Baby Bird, is a Conure, and Max is an African Grey Parrot that she rescued. Bobby and Bre are Kimmi's spoiled rotten Ragdolls and they definitely know it!
