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
I have been a patient of Dr. Harrell for two years, and have had an outstanding experience under his care. From the very first visit, I felt welcomed and well cared for.Dr. Harrell is not only highly skilled but also very empathetic, taking the time to thoroughly listen to my concerns and address them with patience. He explains medical issues in a way that is easy to understand and make sure I feel comfortable with any treatment plan.The office staff is also wonderful—friendly, efficient, and always helpful when it comes to scheduling appointments or handling paperwork.What stands out the most is Dr. Harrell's commitment to patient well-being. Whether it's follow-up calls after procedures or a genuine concern during consultations, I feel like I am in very capable hands.I would highly recommend Dr. Harrell to anyone looking for a dedicated and compassionate healthcare provider.

Dr. Harrell
Disrespected me as a patient. Rolled his eyes like a 12 year old when I tried to explain my frustration. Criticized 2 of my other UCLA doctors. Not a good representation of UCLA Doctors. Did explain why he couldn’t clear me for surgery without any empathy.
