Since 1928 the Callanan family has been providing the highest level of veterinary care for dogs, cats, and small animals. You can feel confident that the management team at every facility has a thorough understanding of wellness/preventative care as well as common and serious diseases. We are well-versed in every type of dog and cat breed and the health concerns, stressors and other factors that may impact your pet.

Your Team

We place great importance on the qualifications, training and temperment of our doctors, technicians and support staff in order to create teams of caring and dedicated professionals.

You are a key component of your pet’s team – a strong doctor-patient/client relationship helps us construct a health plan that works best for your pal. We want to know about your pet’s habits, routine and temperment so we can provide the best care as well as give you strategies and techniques that are realistic for your lifestyle and schedule.


Although wellness care is most effective if it’s been part of your routine since you pal was a puppy or kitten, it’s never too late to start. There are small yet effective ways to keep your pet healthy and we will share these tips so you can take a proactive approach to your pet’s well-being.


Our surgical teams utilize the latest equipment and technology to efficiently perform routine or more complicated operations. Our doctors and techs consistently achieve successful outcomes with close collaboration before, during and after all procedures.

Dignostics and Radiology

The experience and knowledge of our team members are augmented with modern diagnostic and digital radiology equipment that produce fast and accurate results. We can quickly confirm diagnosis and start treatments right away to get your pal on the road to a speedy recovery.


All of our facilities have on-site pharmacies with extensive inventories of veterinary devices, supplies and medications. This provides the ability to quickly and conveniently treat common medical conditions and more serious illnesses such as arthritis, diabetes, and heart conditions.


A clean and healthy mouth is one of the best ways to keep your pet happy and healthy. Regular veterinary dental cleanings for both dogs and cats reduce the risk of many common and serious medical conditions. In addition, at home dental care will contribute greatly to your pet’s overall health.

Prescription Diets

A prescription diet could help you accelerate recovery or stabilize your pet to better manage a chronic illnesses, such as kidney disease, bladder stones, arthritis, heart disease or diabetes. Our doctors will help you understand the nature of the illness and how certain diets may benefit your pet.
