Patients appreciate
Cassie Grimmett receives overwhelmingly positive feedback from patients who consistently praise her exceptional listening skills and the time she takes with each person. Reviewers repeatedly emphasize that she never rushes appointments, thoroughly addresses all concerns and questions, and makes patients feel genuinely heard and valued rather than like "just another number." Patients describe her as warm, personable, caring, professional, and knowledgeable, with many noting her excellent bedside manner and ability to explain treatment options clearly. Her thoroughness in examinations and follow-up care stands out, as does her willingness to collaborate with other specialists and respond promptly through the patient portal. Many patients specifically mention recommending her to friends and family, with several stating she is the best provider they have ever had.
Patients also share
Very few areas for improvement emerge from these reviews. One patient mentioned that Cassie seemed less confident in her diagnosis and not very personable during their visit. Another patient noted she was 15 minutes late logging in for a telehealth appointment. A single reviewer observed that while Cassie was methodical in addressing stated concerns, she didn't proactively ask about a visible condition (toenail issues) that the patient hadn't mentioned, though this patient was not overly concerned since they had already scheduled a dermatologist appointment.
