"We signed up for Dr. Keifer’s concierge services in the summer of 2022. He did some initial blood work on me and found my cholesterol was high. After a brief discussion we decided to wait on medication and see if I could lower it by increasing exercise and changing diet. Dr. Kiefer said he would recheck in 3 months. After 3 months I reached out to him to see about rechecking the blood work. He didn’t respond to me regarding scheduling it either before or after Christmas. My wife had to call him to discuss her own test results and she reminded him my blood work needed to be redone. He told her he would call the next day to schedule, he never did. After 2 days my wife reached out to him again and again he said he would call. Once again he did not. This time in a professional and respectful way (my wife and I both work in health care, she as a provider and I as a consultant) my wife emailed him and expressed disappointment that he again failed to schedule my follow up blood work and reminded ...
him I was at a higher risk for stroke. He responded that he had been “busy” (keep in mind we are paying him a monthly fee) and that we should find another provider. So he basically fired us for being called out on not following through or delivering on his service promise. We were left scrambling to find a new provider and astounded by his lack of concern or care. There is a reason he has the review functionality on his Facebook page disabled. We might as well have flushed 6 months of “concierge” fees down the toilet. "

Data Transparency and Trust: Understanding WebMD Doctor Listings and Reviews

We know that finding the right doctor or provider is important to your health. That’s why we want to ensure you have confidence in the provider profiles and listings you see on WebMD Care. Our provider data is sourced from the physicians themselves as well as publicly available databases. Any doctor or provider who claims their profile by verifying themselves can update their information and provide additional data on their specialties, education, accepted insurances, conditions they treat, and procedures they perform.

All the physician and provider reviews on WebMD Care are provided by users just like you. Knowing these reviews provide insight into how other patients feel about a doctor, we maintain internal policies and protocols to ensure the quality and accuracy of all reviews. Providers are not able to remove or modify reviews on their own. Reviews can only be removed after an internal review by our customer service team.

We value your input and encourage you to reach out to our support team if you encounter any issues.
