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.

Terrible! He is rude, took incomplete & inaccurate notes on my symptoms, did not answer a single one of my heart related questions pertaining to my cardiac test results- just suggested I ask my GP?? He seemed completely uninterested in his work or me as a patient. The only reason I went to him is his schedule is wide open and I was able to get in the next day. All the other cardiologists are booked weeks out. There is good reason he has so few patients.

No !! He doesn’t listen and he was very rude.I am an athlete that has taught sports all my life, i’m not a complainer. He was mad that I got a second opinion that is absolutely arrogant and ridiculous I would never go to him and I would never recommend him to anybody..

Dr. Gim's medical decision-making was appropriate & good for my elderly mother. However, he handled a telephone conversation very unprofessionally with my parents concerning a miscommunication with his office staff. With the exception of the physician assistants & pacemaker technicians who were very caring, there is a culture of indifference among the office staff. Communication breakdowns occurred more than once between Dr. Gim & his staff, & vice versa. I hope Dr. Gim can improve this.
