Dr. Xander Simunek is now our vet and today at our two dogs’ annual wellness exams, it was so reassuring to see how calm both dogs were around Dr. Simunek and vet tech Michelle, which hasn’t been my or their past experiences with other vets.

Our 1.5 year old dog had some unfortunate vet visits when she was younger that contributed to a significant fearfulness when going to the vet. We were ready for a change from our prior vet and from the first call to GAH I knew this would be a better experience for all of us. Dr Simunek, Justin, and the entire front desk staff have gone above and beyond to help our dog feel safe and secure at the vet and have been so patient working with me and our dog to build up her trust with them. Even so much as having her favorite treats ready and waiting ahead of her appointment. We’ve made such great progress in just a few visits and the care she’s received has been top notch.

Every Doctor has been highly skilled and knowledgeable. Over the years they have cared for 4 of our dogs. They have diagnosed and treated a variety of health issues from relatively minor to very serious. They have performed dental cleaning, bladder stone surgery, and neutering. They were instrumental in quickly securing an appointment with a veterinarian oncologist when we were on a waiting list and not expecting to be seen for a month. They have been kind and compassionate helping with end of life decisions. The office staff and techs have always been friendly and helpful. During our most recent visit we saw the major renovation being done to the office and treatment rooms and are excited for the upgrade.

GAH has cared for 8 dogs in my family over the past 42 years. Doctors and staff are knowledgable and more importantly they truly care about your pet. Facility is always clean and up to date. Wouldn’t dream of going elsewhere.

Rick E.

The front desk staff are friendly, helpful and very nice to our rambunctious English bulldog; the doctors take their time to explain their diagnosis and treatment. The fees are fair. We were very nervous about our pet’s neuter because of the risk for Bulldogs with anesthesia, they were understanding, took great precautions and our sweet mister is recovering perfectly.

Verna E.

I cannot say enough good things about this Animal Hospital. Not only are they kind and compassion but they are NOT looking to sell anything or talk you into unnecessary procedures or meds.

Laura M.
