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 customer service and very smart doctor
I have left voicemails with two other doctors at Cedars and it's been over a week and I still have no response. Within this week, I have already gotten in to see Dr. Ahn and gotten blood work AND results. It has been a pleasure working with a team that is responsive. Dr. Ahn sat down with me and explained everything very clearly and made me feel very comfortable. He even did my blood work (not leaving me with a nurse). His office is small and feels like a family environment. I'm very happy I found them!

Dr. Ahn is by far the best doctor I’ve ever had. He’s punctual, professional and most importantly, he’s incredibly intelligent. Dr. Ahn will listen to you and he will never be in a rush to see his next patient. I strongly urge you to give Dr. Ahn a try. I promise you won’t be disappointed.

I've been on the road for 2 hrs left a message the first time since they were not open yet, called a second time to notify I was going to be late and was informed to reschedule after I was 90% there. This is a ridiculous office no wonder they have a 3.5 rating. avoid at all costs. Blamed for accidents on the fwy for not having made it on time plus receptionist needs an attitude adjustment big time. Did I mention worst first impression as a doctor? So how was Dr. Ahn as a doctor I will never know, and will not go back. What a horrible experience.

Without question, the best doctor I’ve had in my life… We’ve been seeing Dr. Ahn for over 20 years now and never have any of the dozens of people I’ve referred to him been anything but as blown away by him and his staff as we are. He is exceptionally thorough, incredibly available under urgent circumstances, and just an absolutely miraculous, wonderful endocrinologist and general practitioner. I was originally referred to him by my neurosurgeon over 20 years ago. He is THE BEST!!!

Saw me right away at appointment time. I moved to L.A. from TX and was able to stay on Vyvanse for weight loss. Helped find new drugs that would help fight my diabetes as well as contribute to weight loss. I found him very knowledgeable about current medical approach to combating my issues and very friendly. I highly recommend this Doctor one of the best I have come across in my 47 years.
