Meet the Team

Liza Pfaff, DVM, PhD

Dr. Liza grew up in the Chicago area and she earned her Bachelor’s degree in Environmental and Evolutionary Biology from Dartmouth College in New Hampshire.  She earned both a Ph.D. (Clinical Sciences, Cancer Biology) and her Doctor of Veterinary Medicine from Colorado State University.  See her full CV here.


Dr. Liza worked at Homeward Bound Animal Hospital and Homestead Animal Hospital before deciding to open her own practice.  She
 is excited to be Fear Free Certified – this is a maturation of her gentle style of medicine and she looks forward to sharing it with all of her patients and clients.​

She loves seeing patients of all shapes and sizes – from reptiles, birds, and pocket pets to cats and dogs to small ruminants, llamas and alpacas.  In her spare time, you will find her golfing, trying to tire out her crazy dog family or playing with her vinyl record collection.

Becca — Certified Veterinary Technician, Practice Manager

I graduated from Bel-Rea Institute of Animal Technology in 2015 and I became Fear Free Certified in 2018.

I began my CVT career in a multi-specialty hospital spending time in many different departments but found I had a particular passion for General Practice. I love building a relationship with the pets and owners and seeing how they grow and change through the years.

When I saw that CCAH was looking for a CVT, I jumped at the chance to work with a Fear Free Certified Hospital and at the opportunity to provide care for not just fur-babies, but feathered, scaled, and quilled babies too!

I spent a two-year term as V.P. on the Colorado Association of Certified Veterinary Technicians (CACVT) working to advance and improve the Veterinary Technician field.

While with CCAH, I have worked my way up to becoming Practice Manager and continue working to improve my skills and knowledge.

In my free time I enjoy knitting, acrylic painting, spending time with my family and my four chihuahua mixes.

Amelia Certified Veterinary Technician, Equipment Manager

Amelia joined the Critter Care team in March 2021. She enjoys working with all the different species and is so excited to be at a clinic that can see them all. Her journey with veterinary medicine started with a seasonal position at a wildlife rehabilitation center. She felt so much fulfillment in being able to help animals feel better. She later went on to become a Certified Veterinary Technician after studying at Bel Rea Institute of Animal Technology. Years later, Amelia is still helping animals of all sorts, both wild and companion.

When she is not at work snuggling all the pets, she is at home snuggling her own pets: three birds and two kitties. In her free time, she enjoys singing, dancing, seeing live music, being in nature, and gardening. She loves plants of all sorts and may or may not have too many house plants (is there such a thing?).

Tiffany – Client Services Representative

Tiffany was born in Illinois and moved to Colorado when she was in third grade. She’s had many pets while growing up including dogs, rats, sugar gliders, and she fostered many, many kittens for DDFL as a teenager.

She started out spending just one day a week with us as a receptionist. She has since established herself into a full-time role handling all the front desk, reception responsibilities as well as uncountable other tasks throughout the hospital.

In her free time, Tiffany enjoys acrylic pour painting and creating new things on her Cricut, gaming and playing basketball with her partner.
