Welcome to Crabapple Knoll Veterinary Clinic


New Covid Procedures 1/13/21

We wanted to let everyone know we have changed a few of our procedures due to the rise in Covid-19 cases in Georgia. We have implemented the following changes to lessen the risk of exposure to our staff and our clients.


  • To limit the amount of people waiting in our lobby we will be doing curbside check-ins. We ask that you call us when you arrive to let us know you are here for your appointment. Once we have an exam room available for you we will call you to let you know you can come in.
  • After your appointment we will ask that you wait in the exam room to be billed out.
  • We are requiring everyone that enters the building to wear a mask or face covering, if you don’t have one we will provide one for you.
  • We also have curbside service available for our clients that can’t wear a mask or don’t want to come into the building. We will also deliver food and medications to your car. We ask for you to stay in your car and call us to let us know you have arrived and we will send someone out to your car.


Due to these changes it is best if you call to schedule an appointment or let us know you are stopping by to pick up food or medicine. We will have your products ready to help reduce any possible wait time.

 We love all our patients and clients and want to continue to be here for you, so we ask for your patience and understanding.


Thank you,

The Gaston Family
