O'Fallon Animal Hospital

Dr. McManus is absolutely the best vet! She is very caring and straightforward, but most importantly I can tell she genuinely cares about my dog and her health. All of the supporting staff make you feel very welcome. Communication is excellent!

Dr. McManus and Dr. Callaway continue to go above and beyond with their care each time we see them. These doctors have saved our dogs lives multiple times. Their staff is top notch, and is the most professional and kind group you’ll ever encounter. We are forever grateful.

Dr. Callaway is the nicest, most compassionate vet I have ever had. She truly cares about the animals. Her staff is top notch and ready to help. They were able to squeeze me in-between other patients as cats are very hard to get into carriers and will hide just at the site of the carrier, so making an appointment is difficult. I followed Dr. Callaway from her previous office as I liked her that much !!

Wonderful experience. Have a nervous golden doodle that needs sedation grooming and they made it so easy! It's very clear they are an amazing team and love their customers. They treated my pup with so much kindness. 100/10 would recommend. THANK YOU ♡

Highly recommend! OAH got me in quickly and everyone was incredibly friendly! The vet and techs were so good with my nervous cats and gave them their vaccines seamlessly. The vet was also very thorough and took a lot of time to talk with me. Will definitely be back!

I've been taking my gur babies to Dr Callaway for over 10 years. She is amazing. She caught and treated my diabetic cat for years giving us more years together. She and her staff were beyond kind and compassionate when it came time to say goodbye. Every time We've had an emergency with one of our pets they've made time to see them. I can't say enough good things about our experiences with Dr. Callaway and her staff. If you're looking for a vet definitely check her out. We drive an hour to see her and it's worth the drive.

Dr. McManus took such good care of my cat, Stinky, and my cat has never enjoyed going to the vet before until she saw Dr. McManus. She is very personable and makes sure she takes her time with you to explain everything as well as treating your pet like it’s her own. Highly recommend!
