About Bliss Animal Hospital Get to know your Lake Forest veterinarian.

We live at a time where pets have become true members of the family, while veterinary medicine has felt less and less personal. We are changing that.

Dr. Nayara Pataro and Dr. Sam Amirshahi founded Bliss Animal Hospital because they passionately believe that veterinary medicine works best when we focus on relationships—taking the time to understand you and your pet as individuals. We listen to your unique questions, concerns, needs, and beliefs. By getting to know your pet’s health and behavioral baseline, we can quickly recognize when something is amiss. This approach leads to better medicine, happier people, and healthier pets.
It starts with relationships
A fluffy orange cat with green eyes lies comfortably on a bed or couch, looking directly at the camera. The background is softly blurred, featuring what appears to be shelves filled with books or various items, as if the cozy scene was captured by a vet during a calm moment at the clinic. A small dog with white fur and brown patches stands attentively on a vibrant green field, tongue out and ears perked, surrounded by lush greenery and trees in the background on a sunny day, ready for his next visit to the vet.

Culture We see a different way to build a veterinary practice. One where we start by empowering members of our team to do the best work of their lives. To love their work, constantly learn, evolve, and grow, and work dynamically with each other to solve the hard cases and become consistently excellent. 

What does that mean? No gaps in communication, no balls dropped, and no feeling like you aren’t seen, heard, or cared for. Here, you and your pet will be cared for by a team who is deeply connective, communicative, and focused on one thing: making sure you and your pet are cared for like we would want our own family members to be cared for. Because to us, you are.

We love training and technology, treatments and protocols. But to us, there is something far deeper to love… there is magic in medicine. In the ability to make such a profound difference in the lives of people and pets. To us, caring for your pet is so much more than just a profession. It is our calling in life. Every single thing we do is about helping your pet live the best life possible. Call us now, and we’ll make a difference in yours. We love training and technology, treatments and protocols.

The dog has floppy ears and a smooth, solid shape, with simple lines outlining its form. Perfect for any vet clinic's branding, the background of the image is transparent.

Proud to serve our Lake Forest and Orange County community
