Where healing meets heart … and pets are family.

Welcome to our family

The perfect fit for your pet’s care

Choosing a veterinarian is about finding the right fit for your family. Great care comes from four pieces, each shaped to fit the others, and none of them is complete on its own.

Your pet
You
Us
Together
  1. Your pet is the heart of the puzzle Every other piece is shaped around them: who they are, how they live, and what they need to feel their best.
  2. You connect right alongside You bring the daily love, the routines, and the small changes only you would notice. Nobody knows your pet the way you do.
  3. We lock into place with you We bring modern veterinary medicine with old-fashioned caring. Your pet gets conventional and holistic options, explained in plain language and built around everything you’ve shared with us.
  4. Together, the picture is complete When all four pieces connect, you get a true partnership that honors the bond you share, from the first appointment through the golden years. Welcome to the family.

What sets us apart

The Countrycare difference

Our mission is simple: to honor and protect the human-animal bond by giving your pet an innovative healthcare experience built around their unique life story. That starts with how we practice medicine; we don’t believe in one-size-fits-all care. Whether it is advanced diagnostics for early disease detection or a gentle, multi-modal plan for senior arthritis, our goal stays the same: to give you the highest quality of time together.

Our mission
  • A Countrycare veterinarian stroking a guinea pig on the exam table, face close to it.
  • A woman holds her shepherd mix’s paw while he leans in, tongue out.
  • A young dog offers its paw to its owner’s open hand on the grass.
  • An older terrier rests its chin on its owner’s lap at home.
  • A hand scratches a yellow Labrador’s chin as he closes his eyes.

Care for every age

A lifetime of vitality, every step of the way

Every stage of your pet’s life brings new joys, new milestones, and new healthcare needs. We’re with you through every single one of them. Our goal isn’t just to treat illness, but to maximize your pet’s longevity, vitality, and happiness from their first playful pounces to their golden senior years.

In their words

The hearts we’ve touched

“Dr. Heintz took the time to listen to my concerns and was very patient with my nervous dog. She even introduced herself when we stopped in for a ‘happy visit’ to get my dog used to the facility and associate it with positive things. She was very understanding and knowledgeable in how to approach my dog who is extremely fearful of strangers and also provided great treatment for my dog! It meant so much to me to have her take the time needed with my dog so she can get the care she needs!”

“As always, the Country Care staff were all very friendly and helpful. We did not have a true emergency. But our dog, Russell, needed medical attention right away and we were so happy we were seen quickly. We appreciate the Vet Tech listening to our concerns and the full history of the situation. And everyone showed that they really cared about Russell.”

Therese D.

“I LOVE Countrycare! You really feel like family when you walk in. I’ve been a client many years and always refer people when they need a vet to listen. Listening to your clients and their worries, fears, needs is soooo important. Thank you for always Listening!”

“I have been going to Country Care for over 30 years. Everyone there is very friendly, compassionate, and takes the time to listen to your concerns and answer questions. I highly recommend them to everyone.”

“I brought my boy to Country Care several years ago seeking a second opinion. He was sick and not getting better and no true diagnosis. After the first appointment not only did I have a diagnosis but a treatment plan that worked! He has been there since that day and they have, without a doubt, saved his life. He is a diabetic and has Cushing’s Disease. Their dedication and determination brought everything under control and he is a happy boy today. Thanks to their care he will be a part of my life for many years!”
