Our family trusts no one with the care of our fur babies except Dr. Sam. We have had many dogs he has taken care over the years and he has done so with exemplary care and genuine compassion in a way no other vet we've had before has done. He cares, plain and simple. As our dogs aged and more things came up with their health, he was the vet we turned to for the expertise and treatment options that were best for us to pursue. We've got a new puppy now and we are looking forward to Dr. Sam and Bliss providing the same stellar care for this little one as all our others. Do yourself and your pet a favor, leave the corporate vet services that are only interested in their bottom line to others that don't know better and choose the team at Bliss, you won't regret it, I know we haven't.

Awsome assistance. Dr.Nayara took time to patiently make Chuck (our 90 pound hovawart mix) confortable to get examined and vaccinated with no sedatives. They also get us involved and aware of each step, greatly overcoming his 'vet care' trauma. Congratulations for the great job!!!

Awesome staff and vet. Definitely thankful I found them to care for my senior cat. Very knowledgeable and caring staff. First visit, stayed in his crate. Second/third visit, he walked around. :)

Dr. Sam and team are absolutely the best. We followed them here when they started their practice as they provided the best service. Their team helps us at home at times as well when we had one of our doggies really struggling. Bliss is *the best*!!

Dr Sam and his staff are the best. Although my 8 month old puppy, Bolt, does not like going to Vet, the staff makes him feel special and cared for when he is goes to get care. Recently, my Bolt had severe diarrhea and the staff called the next day after visit to check in on Bolt, made us feel like we were not alone as it can be very frightening when your puppy is sick, thank you so much to all the staff.

My dog had been experiencing vomiting and diarrhea for five days. Normally, he recovers on his own, but this time was the worst. When I visited the hospital, everyone was incredibly kind, patient, and understanding. You can truly feel their love for dogs—even the front desk staff took the time to listen carefully to everything that happened.

The pricing is also reasonable. They clearly explain all the tests and treatment options, allowing you to decide what’s best. I chose to remove some of the suggested tests, and they were very respectful—no pressure

Most importantly, my dog is fine now! After just one visit yesterday, he’s back to his energetic self. Mommy is so happy! Thank you

The Best! Super Kind, Friendly, knowledgable staff. They genuinely care for you pet as if it were their own, or at least make you feel like they do. They are the most affordable and cost effective while maintaining Top Notch Care for your beloved pets.

Cant say enough nice things about this place or the staff. They even call a couple days after your pet was treated to check on them. Wow!

If I could give them 10 stars ⭐️instead of 5, I would.

The Dr. and staff were so amazing, helpful, informative and really listened. I felt comfortable and at ease that my puppy Moose was being well taken care of; Moose loved giving and getting attention as well. We can’t wait to come back feeling better and ready for routine checkups!!

I cannot give Bliss enough praise for the level of care, compassion, and professionalism they deliver! I took my newly adopted Aussie, Lacey, to get checked out for an eye irritation and to remove her sutures from her spay. Every single person that I spoke to was so kind and eager to help us.

Kiana was great with assessing the current state with Lacey and providing education on their process and what next steps would look like. Dr. Nai came in and sat down with us and the two of them were able to calm down Lacey and really get her comfortable enough to provide treatment. By the end of it, Lacey was doing tricks for treats for them!!

Even after completing the necessary treatment for the eye and sutures, Kiana went over a wellness checklist with me to ensure I knew everything that I needed to provide the best level of care for Lacey. We went over dental health, potential diseases in the breed and suggestions for preventative measures to make sure she stays healthy. We ended up going with a couple of vaccines to protect Lacey as we are outside a lot and they did it on her without any struggle whatsoever!

Everyone here cares so much about providing the best care possible for the animals that come through their door and are also there to provide education and compassion while doing it. This is my go to vet!!!

Making an appointment was very easy and convenient. Bliss animal Hospital is conveniently located with ample parking. Dr Sam Amirshahi and his staff are friendly, professional and knowledgeable. They treated my dog as if she were their own. Dr Sam quickly diagnosed my dog’s illness and formulated a treatment plan. The staff ensures that you understand the recommended services and costs before proceeding. I highly recommend Bliss Animal Hospital.

First time visit to Bliss and the experience was amazing! From the first phone call, and experience at the front desk arriving , to Dr Pataro and Mandy, and Kiana who gave our cat a shot, all were so friendly and welcoming. Their care with, and for my cat as well was wonderful. Bringing the rest of our pets there from now on. Highly recommend Bliss!!

Dr. Nai is my go-to veterinarian for my fur baby, and I can't recommend her enough. She's professional, caring, and always resolves any issues my pet may have. The Bliss Hospital is also well-equipped, and their staff is fantastic.

So happy to have found Bliss Animal Hospital! If you were like me wondering where our amazing vets Dr. Sam and Dr. Pataro ended up-this is the place! Right next to Home Depot the facility is new and equipped with everything for your pets needs. My dog Julep has been seeing Dr. Sam since she was a puppy. The staff is so friendly and everyone is warm and welcoming. Great prices and packages for your pets exams too! I am excited to have Bliss Animal Hospital as our new vet. Highly recommend!

2. Friendly and Welcoming Staff: The entire team at Bliss was friendly, approachable, and genuinely interested in Poppy’s well-being.
3. Poppy’s Verdict: Poppy loved Dr. Nai and the staff. She got the royal treatment, and even some treats!
