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.

Dr. Lee ordered expensive test (>$4000) without my consent. When I tried contacting his office, they told me he was no longer working there. Extremely frustrated with the quality of service.

I was very impressed with Dr. Lee. He is not only an excellent specialist but also an exceptional human being. Even though I was a new patient he spent a lot of time with me, he was very thorough, very attentive, and very patient. He thought of all possibilities and made sure that all necessary tests were done. He also made sue that I understood every detail we were discussing and that I felt nothing was neglected. I am very fortunate to be his patient. I know that I am in good hands and I feel safe with Dr. Lee and with his team.

Dr. Lee is a caring, accessible and professional who treats his patients with respect and concern. He is attentive and responds to questions. He explains everything so that the patient understands. His "bedside manner" is reassuring and comforting. He takes time so that as a patient i never felt rushed as is often the case with many of my doctors.

Dr. Lee has been nothing short of amazing. He’s been very thorough and patient since my unfortunate diagnosis of AML at the end of 2020. Both inpatient and outpatient his bedside manner is courteous, compassionate and informative. Dr Lee and his entire team nurses and administrators have been a source of great comfort during such an emotional time of my life. His remarkable team of nurses (Michelle, Ayelet, etc....) and administrators even helped me secure a grant for medication that would’ve been terribly expensive. In my 79 years, I’ve always been fortunate to have the best doctors. Dr Lee is at the top of I my list. He’s also been extremely responsive when communicating with my son I cannot song his praises high enough.
