Patients appreciate
Diana Nanayakkara receives overwhelmingly positive feedback from patients who consistently praise her exceptional communication skills and thorough approach to care. Patients repeatedly highlight that she takes time to explain medical information in understandable terms, never rushes appointments, and ensures all questions are answered. Her knowledge and professionalism are frequently mentioned, with many patients describing her as highly competent in cardiac care. Patients particularly appreciate her listening skills, noting that she makes them feel heard and comfortable discussing their concerns. Her warm, caring, and personable demeanor is consistently praised, with patients describing her as kind, empathetic, and genuinely concerned about their wellbeing. Many reviews emphasize that she knows their medical history in detail and provides patient-centered care that makes them feel valued rather than like "just another patient."
Patients also share
The reviews reveal very few areas for improvement, with the vast majority being highly positive ratings. A small number of lower-rated reviews (in the 3-4 star range) offer minimal specific criticism, with comments being generally brief such as "good" or noting the visit met expectations without elaboration. One patient mentioned she was "obviously being rushed" though still rated the experience positively overall and noted she remained kind and professional. The lack of substantive negative feedback or recurring themes of concern suggests minimal opportunities for improvement based on patient perspectives.
