4.9 /5( out of 232 reviews )The patient rating score is an average of all responses on our patient experience survey. The rating averages scores for all questions about care from our providers.
The scale on which responses are measured is 1 to 5 with 5 being the best score.
Patient Comments
Patient comments are gathered from our patient experience survey and displayed in their entirety.
Patients are de-identified for confidentiality and patient privacy.October 30, 2024MORAN EYE CENTERDr Fleckenstein was respectful, listened well and answered well-I felt see viewed me very individually-Many practices use a one size fits all approach whereas Dr. Fleckenstein didn't try to fit me into a specific box (a certain protocol the steps of which other practices follow)
October 29, 2024MORAN EYE CENTERShe is a kind person.
October 19, 2024MORAN EYE CENTERShe takes time to explain, especially to reiterate things to NOT be worried about.
October 19, 2024MORAN EYE CENTERShe is the best! So upbeat every time.
October 18, 2024MORAN EYE CENTERTrust, respect, affection and a measure of humor thrown in comes to mind.
October 17, 2024MORAN EYE CENTERExcellent. One of the best doctors I have ever encountered.
October 12, 2024MORAN EYE CENTERDr. Fleckenstein simply the best. Always begins by asking how my eyes are doing and seeking input about any detail. Her treatment approach is very professional and gives me great confidence. I'll be her patient flor the long term with confidence.
October 07, 2024MORAN EYE CENTERShe was kind and answered questions. She was very careful not to hurt me.
October 04, 2024MORAN EYE CENTERShe is very business in her approach. Explaines what is happening and is quick with procedure which b Is great.
