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.

Every time I visit Dr. Koo, I feel confident that she has done an excellent review and diagnosis. She takes the extra time to make sure I have no followup questions. In addition, she always ask about the family and how we are all doing. She makes visits to the doctor something to look forward to!!!!

Dr. Koo is one of my all-time favorite doctors! She is personable and very thorough and explains things in a very understandable manner. Her staff is top-notch as well. It is always a pleasant experience to come to Atlanta North Dermatology, even when the news and treatment is not ideal. My husband and I are both patients and we appreciate and value the care we receive very much.

Ten years ago I got the shingles right before Easter weekend. It was on a Friday around noon. I did not know what to do but decided to take a chance and called her office. She had trained her staff to discern a real emergency and Dr. Koo saw me before her office closed. The rest is history. I've been seeing her every year and as I have aged, she has taken care of every skin need that has come up...she even encourages one's questions! She is a blessing!
