Patients appreciate
Cassie Grimmett, FNP, is consistently praised by patients for her exceptional listening skills and thoroughness. Across hundreds of reviews, patients repeatedly highlight that Cassie takes her time during appointments, never makes them feel rushed, and genuinely engages with their concerns. Her warm, caring, and personable demeanor is frequently mentioned, with many patients describing her as kind, compassionate, and easy to talk to.

Several long-term patients specifically mention their loyalty to her over multiple years, and many have recommended her to friends and family members.
Patients also share
Opportunities for improvement noted in the reviews are minimal and infrequent. One reviewer mentioned that Cassie seemed less confident in her diagnosis and not very personable during that particular visit. Another noted a 15-minute delay at the start of a telehealth appointment. A third reviewer felt that Cassie missed an opportunity to address a visible condition on their toes during an exam, though that patient acknowledged it was not a major concern. These isolated observations stand out precisely because they are so rare among an otherwise overwhelmingly positive body of feedback.
