Patients appreciate
Diana Nanayakkara, ACNP, receives overwhelmingly positive feedback from her patients, with the vast majority of reviews awarding five stars. Patients consistently praise her thoroughness, medical knowledge, and professionalism, frequently noting that she takes time to explain diagnoses, test results, and treatment options in terms they can understand. Many reviewers highlight her strong listening skills and the fact that she answers all their questions without making them feel rushed. She is also repeatedly described as caring, kind, personable, and attentive, with several patients specifically appreciating her promptness, efficient scheduling, and ability to fit them in for urgent needs. A number of reviews mention that she reviews patient history in detail before appointments and provides clear, actionable guidance for follow-up care, leaving patients feeling confident and well-informed about their health.
Patients also share
Constructive feedback in the reviews is minimal and largely isolated to a few individual comments rather than recurring themes. One review (4.83 stars) described a stressful situation in which a surgical clearance was delayed, though the issue was ultimately resolved before the scheduled procedure. Another single review (3.87 stars) noted that she could not answer all of the patient's questions, and a separate lower-rated review (3.23 stars) simply indicated the experience did not fully meet expectations without further detail. These comments appear to be exceptions rather than common concerns, as the overwhelming majority of reviews report no issues with her care.
