We have been taking our cat here since we adopted him more than 10 years ago - at the recommendation of Elmbrook Humane Society. They are available 24 hours a day and ready for both emergencies and healthy pet care.Christine M.Christine M. ★★★★★ Highly recommend Mayfair Animal Wellness Clinic! The location is super convenient with ample parking. The staff is kind and courteous and genuinely cares for the health and well-being of my pet. They do such a good job making my dog - and me - feel comfortable and safe, providing plenty of treats and love, and thorough explanations and options for diagnoses and treatment. We’ve been patients since we rescued my dog over 5 years ago and have been so pleased with the level of service and support we’ve consistently received. If you are in need of medical care for your pet, consider Mayfair Animal Wellness Clinic!Monica R.Monica R. ★★★★★ I am so overwhelmingly thankful for this clinic. I have been bringing my dog, Loki, here and at the ER for numerous reasons over the last few years and he has always received outstanding care. I have always felt that his health and wellness is truly a top priority at Mayfair and I am so fortunate that I can look up to them for everything--from suspicious eye boogers to major surgeries. I trust every single vet and tech in that building and I know if my ole' boy could say "thank you" to each and every one of them, he absolutely would. Thanks to their swift action on Loki's surgery he may still have an opportunity to run around out in the sun before it gets cold again. Truly blessed to know I can count on them.Heather P.Heather P. ★★★★★ Wonderful facility and complete staff was excellent! From start to finish All were fabulous!

Her holistic approach and recommendations (like acupuncture) have really helped my dog! The staff is kind and always smiling too! I look forward to going back with my other pets!Ellie K.Ellie K. ★★★★★ Having a mini zoo, some with special needs; it's really important to find vets that care more about the time spent and not the money spent on the fur babies. I thank the wellness staff often and recommend them every chance we get!Bethany B.Bethany B.js_loader
