Overall sentiment across review platforms: negative
- WebMD (specific to Dr. Brian Ringhofer): 2.5 out of 5 stars (8 ratings and 3 reviews)
Patients praise
- Some individual physicians at the practice have high ratings (e.g., Dr. Robyn H. Jacobs)
Common complaints
- Lack of communication from the doctor (staff answers majority of calls/messages)
- Feeling ignored when attempting to resolve issues with the office
- Perceived lack of empathy and professionalism
- Insufficient explanations for medical conditions or treatment plans
"Also had his staff answer 90% of the call/messages I sent so half the time I don't even get to hear his actual opinion. When I reached out to Mercy to report these issues my response was ignored and nobody followed up with me to resolve."
— WebMD user review for Dr. Brian Ringhofer"I would not recommend this doctor. He is extremely unprofessional and lacks empathy. My wife left crying... A kidney doctor, telling someone that is truly saddening."
