Keystone Veterinary Hospital Newtown, Pennsylvania

Dr. Tierney is absolutely amazing! I called him about our 4 month old puppy Rosie. She was walking like a drunken sailor, and collapsing on her belly. Dr. Tierney has spent a lot of time discussing Rosie's condition with me. Rosie is visually impaired. He had me change her diet to all natural food, introduced essential oils, and always follows up with me. Three months later, Rosie is doing great! A true miracle! We can't thank Dr. Tierney enough, and are so grateful to have our Rosie back to normal.

I bought my 2 day old puppy there that was suffering from mild hypothermia. Our dog had her puppies while we were on vacation. Paid to keep the dog at the hospital to warm up. About 15 minutes after them swiping my credit card for $379 and leaving our dog in their care. They call me and told me the dog stop breathing and it would be $1000 to resuscitate. If they knew the prognosis for the puppy was low, they should have told me to just take the dog home to die with his mother. Why charge me for a service they never administered? Dishonest and fraudulent practices. Do not trust.

Dr. Tierney is the type of veterinarian you find once in a lifetime. This is NOT a man who guilts you into running frivolous test or pack your bill with excessive treatments, but a doctor who truly cares for the well being of your family be it animal or human. This is NOT your typical veterinarian he is a highly decorated one man show who runs his farm and veterinary practice single handily. This is a man who knows more about animals than you or I could ever hope to forget in a lifetime and someone who will give you the absolute best care for your family no hands down. He has cared for my family's animals tirelessly and given me more time with our elder dogs than I could have ever asked for. I am moving to Florida in a few weeks and my biggest regret will be taking my animals away from this man. Even though I'm 1200 miles away Dr. Tierney will still be the first call I ever make when it comes to the care of my animals. Thank you Dr. T.

This Dr. Has a great plan for my dog. He's called me to check up on her. So thanks for walking me through the process. Tim.

Dr Tierney is the most knowledgeable and caring veterinarian any pet owner could ask for .He treats our miniature horse as well as our dogs . I recommend Keystone Vet Clinic as well as Birchwood Dairy , which is right on the property .

The best veterinary care available. I highly recommend it.

You'll never find A better vet

I have been taking my dogs here for 15 years. They get quality service from a vet that wants the best for my pets.

The only vet not scared of my dog in the area!

We love and highly recommend Dr. Tierney. This is him with my Timmy when he was a puppy on his first visit to him 10 years ago.

Best vet I ever had very knowable and great personality. He explains everything in detail.

Dr. Tierney is a wonderful vet! He answers all my questions and is available for follow up. Would highly recommend!

Do not ever use this vet or the kennel. He has the audacity to call himself a doctor. He is a quack. My friend’s dog was peeing blood for weeks and the vet said give her cranberry supplements. Didn’t do any tests besides urinalysis and …

Excellent veterinarian. Highly recommend Dr. Tierney!
