“I took my bearded dragon to All Pet Animal Hospital for the first time today (due to some health concerns), so I was a new client. The staff was extremely friendly, enthusiastic, and helpful. The check-in questionnaire process was efficient and effective, despite coronavirus related changes to service. They are extremely knowledgeable about reptile husbandry and asked all of the right questions and details about my bearded dragon's enclosure, care, diet, lighting, etc.”
