Patients appreciate
Dr. Olivia Celine Demarta receives overwhelmingly positive feedback from patients, with the vast majority of reviews rating her at or near 5 stars. Patients consistently praise her exceptional listening skills, describing her as attentive, patient, and genuinely interested in their concerns. Her caring and compassionate demeanor is highlighted repeatedly, with patients noting she makes them feel comfortable, heard, and valued rather than rushed. Many reviewers emphasize her professionalism, knowledge, and thoroughness in addressing medical concerns. Her bedside manner is frequently described as excellent, with patients appreciating that she takes time to explain diagnoses, treatment options, and test results in clear, understandable terms. Numerous patients mention they have recommended her to family and friends, and several describe her as the best doctor they have ever had. Her ability to make patients feel respected, not judged, and genuinely cared for stands out as a defining characteristic of her practice.
Patients also share
The reviews reveal very few areas for improvement, with most lower ratings reflecting patients reserving judgment until they have had multiple visits rather than expressing dissatisfaction. A small number of reviews mention that patients were waiting for follow-up conversations or needed more time to fully evaluate the provider-patient relationship. One patient noted a minor complaint about having to drive downtown to the office location, though this was not a reflection on Dr. Demarta's care quality. Overall, the constructive feedback is minimal and does not reveal any consistent patterns of concern or recurring issues with the quality of care provided.
