Dr. Siess was born and raised in Southern California and moved to Flagstaff to attend NAU. She fell in love with the mountains, so she made Flagstaff her permanent home. Dr. Siess started working at Westside in 2008 as a veterinary technician where she quickly made the clients and patients her family.
Michelle has been our Practice Manager since November of 2021. She was previously in retail management, but joined our family because of her true love of animals. She has a dog named Pepper who she loves more than anything! Her favorite animal is a pig because they are incredibly smart and cute. She has been on the game show "Get a Clue" with her mom and sisters, but unfortunately didn't win. When she isn't at work, Michelle enjoys reading, watching movies, and ghost hunting! Chelsea is our in-house "cat whisperer".

NEVER take your animals here please if you care for them. Dr. Siess has no business having a veterinary license, I’m not so sure she does actually. She talked me into insanely expensive ear surgery and then botched it. My cats ear is permanently disfigured. After I brought up my concerns, Dr. Siess had the nerve to call me and scream at me over the phone and threaten to refuse service to my cat and I. have to now take her to a professional vet to be fixed. Please do not give this place any of your money!! They need to be closed down.

Our family dog went into Westside for a routine procedure that led to her death, which the clinic has admitted fault for. Our family does not recommend this clinic as the faulty decisions made led to a healthy 5 year old dog losing her life. We miss her dearly and sadly, the mistake cannot be made right.

I wish I could give westside vet clinic 10 stars! I just recently switched to them and I wish I would have started coming here years ago! They are friendly, have listened to all my concerns with passion, and so far, their pricing is way more affordable than where I was taking my dog before. Joe is so nice and caring every time I talk to him! I cannot say enough good things! I look forward to bringing my dogs here for the years to come.

In May 2022, We needed the Doctor's at Westside Veterinary to come to our home.for our 11 year old Yellow Labrador Gunner (my best friend) This was one of the hardest things we have ever had to do. Westside made it as easy and truly caring as it could have been. Thank you from the bottom of our hearts. Todd & Britney Rice

I brought both of my large dogs in at the same time and the staff was great with them. Staff was very caring, friendly, and professional. The vet was just as caring and professional. She answered all of my questions and addressed all of my concerns. Really happy with my experience all around.

Dr. Maltese at Westside is amazing. She has taken great care of my dogs for almost 3 years now and has always been incredibly professional, kind and caring to myself and my animals. My 3 year old dog Sky does not necessarily like going to the vets office and can be kind of a handful but as soon as she sees Dr. Maltese her tail starts to wage and I swear she even smiles. I will be getting a new puppy soon and there is no one else I would rather take her to than Dr. Maltese!

Thanks to Dr. Maltese Bentley is alive and was able to meet his little brother! If we hadn't come across Dr. Maltese I don't believe he would still be with us. She acted quickly when he showed critical signs of bleeding. Quickly diagnosed him correctly with immune mediated thrombocytopenia. She kept us calm when times were very hard and we weren't sure he was going to pull through.

Always talking us through next steps and keeping us from jumping to the worst conclusions. We are very thankful such a skilled and caring person was available to treat him! I would highly recommend this practice and Dr. Maltese!

I am a Flagstaff local, and have been going to Westside Vet for more than 15 years. Toni Barnes has always been my go-to veterinarian. She cared for Lucille, one of my rescue dogs, from her first puppy days all the way through until it was time for Lucille to cross the Rainbow Bridge. At that time, Dr. Barnes came to my home, so Lucille could pass in peace. Since then I have had half a dozen dogs, all cared for by Toni Barnes. Dr. Barnes is an excellent vet. She is a skilled diagnostician. She communicates well. She is kind and compassionate. I recommend her without any reservations at all.

On March 21, 2022, Westside Vet Clinic (Dr. Barnes) killed my dog. I took my healthy, five-year-old dog in, and she did not come out alive. Dr. Barnes did a procedure on her without asking for my consent, and then she did the procedure so terribly that it killed her. I left with a leash, collar, and box of Kleenex. I don't recommend entrusting your fur children to this clinic or this vet.

I've been taking my 3 dogs and 2 cats to Dr. Calhoun since I adopted my little herd and I absolutely adore her! Respectively, all of them love her as well. My dogs get excited when we sit outside of the Westside doors. Samantha, Kaya, and Ziva say hi. All of the techs are amazing as well. I always speak highly of Westside and will continue to bring my fur babies here. Thank you for all you do.

Dr. Calhoun is nothing short of amazing! She is empathetic, genuine, honest, and connected. I hope never to have to find another provider for my furry family members.

After recently relocating from Sedona to Flagstaff, I needed to find a new regular vet for my 10 year old MinPin/Chihuahua, Emma. It didn't take long to discover Westside Veterinary Clinic and I was able to easily make an appointment as a new patient (well my dog at least lol) with about a 10 day wait. The visit went well and everyone involved was kind and professional (Chelsea was especially courteous, friendly, and pleasant!). Definitely recommended.

We just moved to Flagstaff and our dog ate something in the yard that really upset her tummy. We were able to get a next day appointment and Dr. Gordon was wonderful explaining everything. Thank you for getting our puppy well!

We have now seen three of the four doctors at the clinic and there are NO words to say how blown away we have been by their care.
Moving here was nerve wrecking because we adored our vet and saw him for 20 years. But a neighbor was kind enough to recommend Dr.Seiss, and off we went. With a pack of senior dogs, we have been in often. With a team of doctors available, we are able to get in.

A tad nervous about seeing someone new? Well let me say don't worry!!! We have seen Dr.Seiss, Dr.Calhoun and Dr.Gordon and with each experience I am BLOWN AWAY by their expertise, knowledge, recommendations that align with my feelings toward medical care. Their CARE is clear, their time spent with my dog and ME explaining what's going on, what our options are.

I love and appreciate their methods, I am a let's try this and see type person, and we have been able to exercise that process with my crew. Let's do this first, then if we don't get a response we will try this. Cautious, never too much, never over medicated, never overboard.
ALWAYS caring, always kind, always feeling like they're doing what's best for my dogs....I cannot say how this has made my heart happy.

The move was rough, but having a vet you freaking love and trust is priceless. Having a vet who cares deeply and knows their stuff is heart warming, comforting and the relationship we are building is like none other. This team is top notch. A+. Ten. There is a new degree of comfort in knowing no matter who we see, I can 100% feel good about that. The team is DYNAMIC there. Absolutely dynamic.

I highly recommend. Very professional and kind. Our dog had an appointment for his shot today. During the weekend he split his paw open. They were booked solid but were nice enough & caring enough to take him and get him sutured up. They took excellent care of him...made time for him & his needs. Treated him & us like family.Awesome job Westside!!! I can't thank you enough!!!!

Simply the best, most thorough, thoughtful, giving Veterinarians you will ever find. I have lived in three places with my dog, and tried two others vets just in Flagstaff- and this place feels like family every time you speak with a doctor. After my first visit, Dr. Gordan called to follow up on how he was doing after hours. She also worked with a Phx study team to help me financially in paying.

The second time I went in for a check up, she again called after hours to check in. Now, last Friday I called worried as he was limping badly. Dr. Gordan was not in, so Dr.Barnes took the time to review his charts, and prescribed him something to keep him comfortable without making us come in, until our own doctor could call on Monday. Of course, on Monday she called 30 minutes after they closed and spoke to me for 10 minutes asking thorough questions.

It was like a virtual appointment- and they never pressure you to come in if you do not absolutely need to. I could go on and on. I would trust them over anyone to care for my dog.

This place is amazing. After going to a different clinic and feeling confused, anxious, and distressed I sought out this clinic. The feeling was 100% different. Jenny, one of the vets, took the time to answer all of my questions while sitting on the floor to comfort my dog. She was straightforward but kind, she made me feel confident that she is an expert. I feel so much better about my dog's diagnosis and recovery steps (IVDD diagnosis) after going here. 10 out of 10, would recommend.
