Read What Our Clients Say

  • "So far Dr. Woodley and the staff have been nothing but amazing. I say so far since we've only had two appointments, but in that short time I have become so much better equipped to handle my assistance canine's diagnosis. My girl has been on meds for a couple of weeks and has been doing great. She gives me hope that there is a chance my girl may make it a little longer than predicted and with an awesome quality of life.
    For a holistic approach, Dr. Woodley, by far, is the best choice!"

  • "We love Advanced Animal Care of Colorado, we started bringing our black lab, Keira, here when we moved here from Florida and have never been disappointed! Great service every time, they always lay out options and recommendations, but never force extra tests/shots/etc on us. We get the final say, which I appreciate. We've gone to vets before where we were shamed if we opted out of a certain service, and that doesn't happen here. We got Keira spayed here just yesterday and Dr. Deramus did an awesome job! Keira is doing great! Thanks for taking such great care of our girl! We love AACC!"
