Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Excellent Doctor
Dr. Lengemann has been my primary care physician for many years now and he always takes the time to talk about any needs or concerns I have. He also is straight forward and tells you what you need to hear and not what you want to hear which is incredibly important in a doctor.

The best Internist at Edward Health
Listened to my list of questions and concerns. Has continued to encourage me to control diet and exercise to reduce my risk of diabetes, over past 10 years reducing my A1c from 6.8 to 5.8, in the normal range. Lost 40 pounds and feel great. Advises me on other health concerns, and always positive toward improving health even though I'm turning 78.
