★★★★★ Brought my new rescue pup in for a checkup and left with everything I need and more! This has been my folks vet for 5 animals over the last 20+ years, and I can see why!Shannon LShannon L ★★★★★ I'm a new client here. The place I had been going to for years closed their vet facility, and I had been looking for a new place that felt right for just over a year now. We've had some unpleasant experiences between my last place closing down and finding Rocky Mountain Small Animal Hospital.This was the first place that I had a good feeling with over the phone, so I decided to bring my kitty in for an exam.Everyone was friendly, gentle, and loving with her. One of the last places I took her had her so scared and stressed that she came out drooling on herself, which has never happened.I am so happy I found this place! Meeps left so calm that she fell asleep on the ride home instead of meowing through the drive. :)I came in with pre-dental lab work from a different facility, a facility that I did not feel comfortable returning to. I had a few questions on the results, and rather than adding a bunch of expensive tests, they were honest and informed me it wasn't necessary at this time.This place is a breath of fresh air from my interim between my spot closing down and all the unpleasant experiences I and my kitty have had. I am so excited to have found our new spot! Thank you RMSAH 😊CourtneyCourtney ★★★★★ Great vets.Steve J.Steve J. ★★★★★ We have been with Dr Tancher and Rocky small animal hospital since 1991 and the care we receive has been professional, caring and loving towards our family. Our pets have received the best care and when it became “that time” everyone were so grateful to have been a part of our family and pet’s life and cried with us. So thankful to have his team taking care of us.Craig W.Craig W. ★★★★★ I love Rocky Mountain Small Animal Hospital. I have brought several generations of both dogs and cats here since I was a child, and they have always been super helpful, friendly, as well as honest and respectful. I will continue to bring my future pets here as well, as I trust this clinic fully.Dan Farrand (Din V.Dan Farrand (Din V. ★★★★★ Rocky Mountain Small Animal Hospital has bent over backwards to help take care of our diabetic pet. We trust them totally. I'm sure that our dog is still alive and happy because of them.Jeff H.Jeff H. ★★★★★ Always a great experience and happy pups ! ( whether or not they like it lol)Swede G.Swede G. ★★★★★ What a nice Vet, very understanding and acknowledgeable. Took the time to listen and stayed late to take care of my dog. This is a great place for all your pets needs.Steven S.Steven S. ★★★★★ A++ Service. Caring doctors, nurses, and staff. We give it 4 paws up!Lynn K.Lynn K. ★★★★★ 2022-09: I worked here under Dr. Tancher many, many years ago. He was an amazing guy with the desire to help any animal that couldn't speak for themselves. The staff I worked with, and encountered by simply being a patron with my own pets, was great. I realize this was years ago. However, I still have friends in the area who bring their pets here still to this day. So I feel pretty confident with my rating.Katrina H.Katrina H. ★★★★★ Great vet careSusan P.Susan P. ★★★★★ We have been patients of Dr Tancher’s since he opened this practice and we would recommend anyone to go here. Everyone is kind and they LOVE all animals.Suzanne P.Suzanne P. ★★★★★ They have a vet with expertise in hamster health. He kindly ruled out the worst causes of why my daughter's cute hamster experienced some hair loss, and gave us knowledgeable advice on what to do about it. He was also the only person who has held our hamster and didn't get bitten. Very gentle!Bethany K.Bethany K. ★★★★★ Top notch vet. They also provide boarding.No O.No O. ★★★★★ This was my first experience with Ricky Mountain Small Animal hospital. Dr. Hanson was incredibly kind and caring towards my cat and myself. The staff is very friendly and professional. I will be going back to this office for any future vet needs for my animals.Melissa K.Melissa K. ★★★★★ The staff here is very caring and they handled my dramatic husky wonderfully! I was also very pleased that their prices for dental work were quite reasonable! I am glad to use this clinic as our vet.Erica M.Erica M. ★★★★★ Called around with some questions I had concerning my five year old black pug. The gal who answered the phone was very knowledgeable and answered all of my questions. What really sold me was she referred to my Marty as kiddo. Never had any children of my own, not even a dog until i was 58. He is literally my child. Looking for a new vet, not happy with the one I have, found it!Rafael D.Rafael D. ★★★★★ I love RMSMAC! They have neutered several of my bunnies and all have been perfect, healed very well, and the staff are all super nice! I highly recommend.Elizabet N.Elizabet N. ★★★★★ Dr. Clark is wonderful. I have always had a great experience at this clinic! I highly recommend them.David H.David H. ★★★★★ They are great.Tammie R.Tammie R. ★★★★★ Dr Bean is the bestDonetteDonette ★★★★★ We have had Dr Jane longer than we have had a pediatrician! She is an amazing provider and we trust her whole heartily to care for our dogs!BlockfeldBlockfeld ★★★★★ Dr. Bean is the best!J 4.J 4. ★★★★★ Friendly staff and very helpful vets. They truly have gone above and beyond to help my dog and guinea pigs.Kevin N.Kevin N. ★★★★★ Wonderful, caring, compassionate people. The entire staff here is incredible, but Dr. Hanson and Dr. Clark in particular go above and beyond to provide quality care for my family's animals. When it came time to make some tough decisions for our elderly cat, Dr. Clark listened to us and worked with us to make sure that we were making the very best choice for our little buddy. Not once have we ever felt pressured into a procedure or medication (something I cant say about many other vets in the area), and the hospital works hard to ensure that you have all the knowledge you need to make informed decisions. Truly a first-rate clinic.Tahoe D.Tahoe D. ★★★★★ I took my Yorkie in because he wasn't feeling well. They made time for him on the same day, which I really appreciated. Long story short, the price came out to a lot, but they worked with me on a payment plan that worked for me, which was super helpful and again very appreciated. They really care about their patients and clients and I will always take my pets to them first.Luke A.Luke A. ★★★★★ Clean, great staffSan D.San D. ★★★★★ They took great care of our cat! Could not have asked fro more.Ned H.Ned H. ★★★★★ Awesome! The entire staff was engaged, helpful, and loving to us and our doggy.William P.William P. ★★★★★ ::Edited to five stars::New experience,Dr Bean is a credit to his profession and the only vet that will ever take my boy to. Dr Bean is down to earth, very realistic and an upfront honest professional. I can't emphasize enough how comfortable and relatable he is with every visit whether that be a major concern or minor. Dr Bean genuinely seems to care about each individual patient.I have never felt rushed or unappreciated over the course of the last four years. My first review of Rocky mountain was after a very impersonal and rushed visit I had with a previous vet. I decided to take a recommendation from a friend and request Dr Bean specifically. My experience with him solidified my decision to only go to Rocky mountain small animal hospital for all my veterinary needs.At no point with Dr Bean did I ever feel like I was being pushed into an unnecessary procedure or medication. He was very upfront about all options that I had for any need for Jax (My 85 lb boxer). Without going into specifics there were, on more than one occasion, recommendations for expensive procedures from other vets at that office that he quickly dismissed and deemed unnecessary.When we take our pets into a vet we need to feel comfortable and confident that the vet has our pets best interest at heart and that we are not just another customer or outlet to gain more in sales for services etc. The down to earth, friendly and upfront nature that Dr Bean brings to the entire experience leaves me reassured that the options recommended to me are exactly what my pet needs. I can't recommend Dr Bean enough. I would absolutely request him specifically if you choose to take your pet here.Old Review 3 stars:Great service and a variety of services. The female veterinarian I had was a bit cold and not very personable. It was very clear that the 'upsale' tactics are drilled into the conversion at every opportunity.J E.J E. ★★★★★ Great with cats! Our cat is a fiesta, picky cat who hates vets and other cats. She loves going here! Dr. Bean is great and the staff is friendly and helpful.Travis B.Travis B. ★★★★★ We love the staff and veterinarians here. They are kind and caring, and great follow up.Amy J.Amy J. ★★★★★ The last place I went wouldn't let me come into the exam room (or even set foot inside the front door) when I took my dog in. I liked that I could enter (after calling) and accompany my dog, and Dr. LaCroix was great! She was kind, gentle and caring. Highly recommend!Diane M.Diane M. ★★★★★ Been bringing our dogs here for years. Very happy with all the services.paul T.paul T. ★★★★★ This place is fantastic! I took my Guinea Pig here for a check up and they are extremely knowledgeable, friendly and professionalDennis BDennis B ★★★★★ Love this place best staff ever all around everyone here is amazing!!!Holly V.Holly V. ★★★★★ We had a funeral to go to and two dogs to board. Our almost 1 yr. old sheepadoodle, Jax and my son's 3 yr. old blk lab, Shadow. Neither had ever boarded before and we wanted to keep the "cousins" together. Jax celebrated his first birthday at the resort with a little party. Macy took pictures for me. Looks like they were both smiling and having a good time at the party! Our pups got to play together and hang out with Robin and Macy.We are so appreciative from the beginning when speaking with Grace, to the experience Robin and Macy gave our pups!I would recommend this resort to any first timers! We will definitely board with them again! Jax and Shadow came home happy.Thank you Grace, Robin, and Macy! You're the best!Connie J.Connie J. ★★★★★ If I could give more than 5 stars, I would!The team at Rocky Mountain Small Animal Hospital was absolutely spectacular when we had to find a place to board our dog last minute. Macy, Grace, and Robin (and everyone else who helped!) we're extremely understanding and compassionate for our situation.This was the first time we ever boarded our dog and they took great care of him. I think he had so much fun he almost didn't want to leave! We will definitely be back for future boarding. Thank you RMSAH for taking such good care of Shadow!!Leanna Rutledge J.Leanna Rutledge J. ★★★★★ Great service during adoptionScott S.Scott S. ★★★★★ Great carung and knowledgeable staff!Laurie E.Laurie E. ★★★★★ Facility is clean, Staff is friendly, Doctor is caring and knowledgeable... highly recommend this place. Been coming here for over 25 yrs and trust them completely.Shel W.Shel W. ★★★★★ Another fantastic visit for our new puppy! Dr. Hansen is so wonderful, and even though we were one of the last appointments of the day, he did not rush us at all. I don't have enough good things to say about this facility. We have been clients for four years now!Annastasia K.Annastasia K. ★★★★☆ Went at 6 am and had to wait till 8 to see the doc because at 7 day shift comes in and does rounds. They don't exam the pet in the exam room, they take them elsewhere to do the exams.Janice N.Janice N.js_loader
