Questions? We Have Answers!

We encourage you to prepare a list of questions prior to your appointment. We're happy to share advice on grooming, diet, behaviors, and more.

Pro Tip: Take a Picture or Video

Take a picture or video! An itch, cough, or shake can be hard to describe, and our pets often don't do things at the vet that we see them do at home. A picture or video can really help our vets narrow down what's going on.

Snacky Pets Encouraged

If possible, don't feed your pet right before a visit. We may use treats to help your pet feel comfortable with us, and we want every appointment to be a positive one!

The Creekview Difference

CONVENIENCE

  • Drop Off Appointments

    For your convenience, we offer “drop-off” appointments. This means you have the option to bring your pet in at the time that works best for you, and leave him/her with us for a couple of hours. Once the doctor has examined your pet, you will receive a call to go over the exam findings. From that point we will organize a pick up time for your pet.

  • Concierge Appointments

    Need some help getting your pet inside? We also offer concierge appointments: simply let the front desk know before your appointment that you would like help with your furry friend, and a member of our team will meet you at your car to help bring your pet inside!

ACCESSIBILITY

  • Virtual Assistant

    Our virtual assistant, Sophie, is available 24/7 to help with appointment requests, online food and medication refills, and other common questions. With Sophie, help is always within paw’s reach! Simply tap or click the blue icon in the bottom right corner to get started.

  • Just Off the 400

    Creekview Veterinary Center is easy to get to, conveniently located just off the NY-400 for a quick and stress-free drive. We also offer a large parking lot, making arrival and visits simple and convenient from start to finish.

LESS STRESS, MORE TAIL WAGS & PURRS!

We know vet visits can be stressful — for pets and their people! At Creekview Veterinary Center, we use a combination of comfort-focused design and gentle care practices to help every visit feel calmer and more comfortable for your furry friend.

Fear-Free Certified Veterinarian

As a Fear-Free Certified veterinarian, Dr. K has specialized training in recognizing and reducing fear, anxiety, and stress in pets during their veterinary visits. She uses gentle handling techniques and low-stress approaches to help make each appointment as calm and comfortable as possible for every patient. Learn more about Fear-Free Certification at https://www.fearfree.com/.

Happy Visits

Sometimes a visit is just about building trust! We offer free Happy Visits during our regular business hours, which let your pet stop by for treats, praise, and positive experiences with our team — no exams required — so the clinic becomes a place they feel good about.

Calm Music

Soft, calming music plays throughout the hospital to help reduce stress and create a soothing atmosphere. It’s a small detail that can make a big difference for anxious pets.

PVPs (Pre-Visit Pharmaceuticals)

For pets who need a little extra support, pre-visit pharmaceuticals can help take the edge off anxiety before they arrive. Used thoughtfully and safely, they make appointments smoother and less stressful for everyone involved.

Pheromones

We use calming pheromones throughout the hospital to help pets feel more relaxed in an unfamiliar environment. These scent signals are species-specific and naturally reassuring.

Quiet Exam Rooms

Our exam rooms are designed to be calm, quiet spaces with minimal distractions. Less noise and movement means pets can settle in more easily and feel secure during their visit.

Policies

For your protection and the safety of your pet and others, we require that all patients be placed on a leash, or contained in pet carriers. All pets are to be properly controlled while in the waiting room and the exam room.

We accept cash, Mastercard/VISA/Discover/American Express and CareCredit. Payment is expected when services are rendered. We will gladly prepare you a written estimate of services prior to the treatment of your pet if you desire. 

In urgent or emergency situations, a pet may require immediate stabilization or life-saving care before a full treatment plan can be discussed. This can include initial diagnostics, pain control, fluid therapy, oxygen support, or other appropriate interventions necessary to stabilize your pet so that further evaluation and treatment can be provided safely. In these cases, you will be asked to review and sign a stabilization consent form that outlines possible services and associated costs.

Please don’t hesitate to speak with us if you have questions about emergency care, financial policies, or how we handle urgent situations. Your peace of mind matters to us.

Payments

Payment options for hospital services include Visa, MasterCard, Discover, American Express, and cash. 

We also accept CareCredit financing.
