About Our Doctors

Dr. Alycia Hagenmaier

I’m a native Phoenician (yes, we really exist) and I earned my undergraduate degree at good old ASU (Arizona State University for the newcomers - go Sun Devils!). After ASU, I headed for vet school at Colorado State University - and I’m proud to say I just earned my DVM!

While I’m a new veterinarian, I’ve actually worked as a vet tech for 10 years, so I’m familiar with all aspects of an animal hospital. I’m particularly interested in allergies and dermatology cases.

One of the most exciting things about joining the AZPetVet team is meeting so many doctors in our family of animal hospitals that share similar interests or specialties.

Everyone benefits from being able to compare notes with colleagues, whether it’s tracking down elusive allergies or something’s particularly puzzling or challenging in a case. I’m looking forward to collaborating with vets who have different experiences to share. We have a pretty strong home team to rely on, and we can always call on the reserves if we need them.

I also love to try new restaurants (there’s never a shortage in Scottsdale), hiking, horse-back riding and camping.

Can’t wait to meet you and your very special pets!
