Reviews
Always available, caring, and competent, whether it's a cat or a dog. Negative reviews because someone can't get their pet treated immediately due to an emergency operation are incomprehensible...
Unfortunately, I discovered this practice far too late. Due to my four-legged friend's medical condition, I have to go to the vet regularly. Since visits are unpredictable, I often go to other vets because he tends to display symptoms during vacations. I've been to just about every vet in the area (and most of them are really good doctors). In my opinion, no one comes close to Dr. Janssen-Sinn. You can tell with every action that her focus is on the animal and nothing else. With every visit, I'm given new, valuable tips to improve my cat's life. She was also the only one who, after a decade, noticed something that any other vet should have seen immediately. While it can take a while in the waiting room, you know that not only your own but all the other animals are receiving the best possible care. Not to mention your friendly manner, which makes the experience all the more enjoyable. Thank you so much for your great work! In my opinion, 5 stars isn't enough for a practice like this!
I'm extremely impressed. The team and the vet deserve two more stars! They explain in great detail what our dog had, how it happened, and what can be done. She helped us when all the other practices were closed. I'm actually very happy that we found this practice. We do have a vet, but I'd like to have my dog treated exclusively by you from now on! I'm really very impressed! Thank you again for helping the little one so quickly ☺️
