Patients appreciate
Cassie Lee Grimmett, FNP, receives overwhelmingly positive feedback from patients who consistently praise her exceptional listening skills and patient-centered approach. Reviewers repeatedly emphasize that she takes time with patients, never rushes appointments, and genuinely listens to their concerns without making them feel like "just another number." Patients describe her as professional, knowledgeable, caring, and thorough in her examinations and assessments. Her bedside manner is frequently highlighted as outstanding, with patients noting she makes them feel comfortable, at ease, and supported during visits. Many reviewers appreciate that she explains treatment options clearly, involves patients in decision-making, and follows up appropriately through the patient portal. Her personable, friendly demeanor combined with clinical competence has earned her strong loyalty, with multiple patients stating they've recommended her to family and friends or switched their entire household to her care.
Patients also share
Very few opportunities for improvement emerge from the reviews. One patient noted a 15-minute wait when the provider was late logging into a virtual visit. Another reviewer mentioned that while the provider was thorough with stated concerns, she didn't proactively address a visible condition (toenail issues) that the patient hadn't mentioned but that was observable during the examination. One patient gave a lower rating expressing that the provider didn't seem very confident in her diagnosis and wasn't very personable, though this appears to be an isolated experience contrary to the vast majority of feedback.
