There is hope.

There is almost always something we can do to help an animal once it’s been diagnosed with cancer. However, having a consultation does not mean you are committing yourself to treating your pet with cancer. We are here to help you make the best decision for your pet, which is sometimes treatment and sometimes not. If you decide to pursue treatment we are able to help assure that chemotherapy, surgery, radiation therapy, and/or immunotherapy are used in the best way to help your pet. If you decide cancer treatment is not the right choice, then we can help you to keep your pet comfortable and prepare for the future. There is no wrong choice.

We believe the clinic environment matters. Not only do we provide the best possible care for patients, with our small, experienced, and friendly team, but we have a beautiful, comfortable and peaceful clinic environment. By having a serene atmosphere limited to only the care of cancer patients, families are encouraged to relax. We know this is a challenging time and we aim help you feel more at peace, so you can focus on your pet. We are unlike any other veterinary cancer center. We are small, experienced, locally-owned, and completely focused on you and your pet.
