About Our Clinic



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!

Dr. Choi treated my precious little Fluffy with all the care and attention you could ever ask for!

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