Welcome to Crabapple Knoll Veterinary Clinic

New Covid-19 Procedures 6/1/2020

Starting Monday June 1st, we will be going back to our regular hours of Monday thru Friday 6:30 am to 9pm and Saturday and Sunday 8am to 5pm.

We will also be opening our building back up to the public Monday, June 1st. We are taking extra safety precautions such as, all of our employees will be wearing face mask, limiting the number of clients waiting in the lobby, and enhanced cleaning which includes disinfecting the exam rooms thoroughly between clients as well as regularly disinfecting surfaces throughout the day.

For those clients that prefer not to come in the building or wait in the lobby, we will still be offering Curbside service and Parking lot check-in. If you would like Curbside service or a parking lot check-in, please let us know when you schedule your pet’s appointment. When you arrive give us a call and we will send an employee out to assist you. With a parking lot check-in, we will check you in from the parking lot, you will wait in your car until we call you to let you know an exam room is available, this way you can avoid waiting in the lobby for an exam room.

We are doing everything we can to accommodate all of our clients and employees safety concerns by offering different options such as Curbside service, a parking lot check-in or regular check-in inside the clinic.

Thank you for your patience and understanding these last couple months. We’re looking forward to seeing everyone’s smiling faces again.
