Dr. Donna Greybek Welcomes You to Our Website


We are located at 162 Washington Valley Rd in Warren, NJ

We wish you and your families a very happy and healthy holiday season!

Our office is now fully OPEN, but we are still offering curbside service for those who would like it.

Everyone is welcome to come in the building, but we are limiting the number of people allowed in the exam rooms.

We strongly recommend everyone wear a mask.

 We will continue to have the PICK UP BOX. It is located to the RIGHT of the planter as you face the building-there is a sign on the building pointing to it.

If you are dropping anything off, please use the Idexx Lab Box which is to the LEFT of the planter as you face the building. Please call and let us know you left something in the Idexx Lab Box so we can bring it inside the building.

If you would like curbside service for an appointment or for pick up, please call 732-356-9889. If we don't answer, we are either on another line or helping another pet. Please LEAVE A MESSAGE with your name and phone number. We will get to you as quickly as we can. 

Please download our App AC of Warren in the App Store for medication or appointment requests and to register your pet and post photos!

Please visit our online pharmacy with Vetsource:


If you feel your pet needs medical care but you are unable to come to the office, you can set up a telemedicine consultation through our app or copy and paste: 

We are also offering Email telemedicine consults. You can email your questions with photos or videos to Turn around time for email consults are 24-72 hours. There is a fee for this service. 

You can download our app "AC of Warren" on the App Store.  Once downloaded, you will need to register. Once registered, reopen the app and tap the bars at the top left corner of the screen (It's a blue bar that says "Welcome"). Scroll down and choose "Schedule Virtual Exam"  and follow the prompts. The calendar in the middle of the screen will allow you to request an in office appointment but not a virtual exam. Please call our regular number (732) 356-9889 if you are having any issues. Please leave a message with your name, your pet's name and that you want to set up a virtual exam. We will return your call and help you. If Dr. feels she needs a "hands on exam" or testing, we will do our best to accommodate each individual on a case by case basis. We can bring your pet into our office while you wait in the car. The Dr. will call you during the exam. If medication is needed, we can deliver it to the car or we offer a home delivery option.

Please note that the telemedicine consultation service is for our current patients only. 

As of this time, there is still no evidence that pets can transmit COVID-19 to us, but we can infect them.
