Starting June 1st, 2021 we will be allowing 1 client into Mayfair Animal Clinic PC for each visit. (click for instructions)

If you would prefer to remain in your car or outside, we will still be offering our current curb-side service. Please stay in our parking lot and have your phone ready.

For in person visit:

Please arrive at least 10 minutes prior to your appointment for over-the-phone check-in.

Once checked in, you will remain in your vehicle or at the outdoor benches until your exam room is ready.

Face masks ARE required to enter the building, no exceptions.

One guest is allowed into the clinic with the animal. Two guests are allowed for euthanasias.

Once in the exam room, we ask that the client remain seated. The doctor will examine your animal and the doctor will discuss a plan with you while a technician assists the doctor in the exam room.

If your pet does not require treatment, you will be billed out in the exam room.

If a plan has been created, your pet will be brought to treatment if needed and we ask that you wait in your car or at the outdoor benches.

You will be billed via phone call at your car or at the outdoor benches. Portable card readers are available if you do not wish to give your payment over the phone.

Medication pick-ups will be allowed into the clinic. We ask that you call when you are here and enter one client at a time due to the close-quarter space of our lobby.

Our exam rooms will be cleaned between each client’s visit.

We ask that everyone respect our process over re-opening to in-person visits as we are trying to accommodate all our clients and employees, vaccinated or not. Our location is a very “tight” space.
