Patient Rating
Patients consistently praise Dr. Callis for strong clinical knowledge, thoroughness, and helpful care coordination, with several noting she reduces medication costs and leverages staff effectively. Many describe her as professional, personable, and effective at teaching trainees while providing clear follow-up and responsive communication. A minority of comments raise concerns about communication style and privacy — some found explanations overly technical or felt she could seem stern or defensive, and a few were uncomfortable with the positioning of assistants or trainees during exams. Overall the feedback is predominantly positive, with occasional issues related to clarity and perceived receptiveness.
Generated via Patient Reviews
The patient rating score is an average of all responses on our patient experience survey. The rating averages scores for all questions about care from our providers. The scale on which responses are measured is 1 to 5 with 5 being the best score.
Patient comments are gathered from our patient experience survey and displayed in their entirety. For the convenience of our visitors, some patient comments have been translated from their original language into English while preserving their original meaning as accurately as possible. Patients are de-identified for confidentiality and patient privacy.
