Dr. Horizon

 “I have seen Dr. Horizon for 10+ years and lately Dr. Shim (same office)..  They are well informed and current with their knowledge. Both have great bedside manner. Dr. Horizon can inject your joint and you won't even feel the needle.  They only run tests you need and have great suggestions for non medical solutions to your problem.  i.e. eating right and exercise.  The office staff is always helpful and easy to deal with.”

“I have seen Dr. Horizon for just under two years now and I travel over an hour to see him which says something since I really hate driving in traffic.  I was extremely surprised to look on Yelp and see some bad reviews for him.  I was expecting to see only 5 stars from reviewers.   I wasn't planning on writing this review but I am now in fairness and appreciation for Dr. Horizon's excellent work on treating me.  I am 50 years old and feel I know good doctors when I see them and went through three other doctors before placing my trust in Dr. Horizon.   This guy is smart, caring and does a great job in figuring out what's going on.  If you need an excellent Rheumatologist don't hesitate and just go see him or at least get a second opinion from him.  I highly expect you will be glad you did.”

“Dr. Horizon has been great. I've seen 8 different doctors this year and he was the only one to figure out what was wrong with me. He is very busy so scheduling is difficult but I highly recommend him.”

“I been treated by Dr. Horizon for over 6 years. From day one, he was able to solve any and problems i raised and has at the time. Since than, he watch my health and make sure that as i get older, i will not get my health in any risk.

I can't thank enough to Dr. Horizon for keep me healthy.


Re all those negative reviews on yelp, i think you eather work for a compititors or just not satisfied patient. In medical it is no gaurenty. If from whatever reason Dr. Horizon wasn't able to help you, i'm sure that he didn't make your health condition worst. However, for no reason, you hurt his business with your negative review.

You should remove your review or give him better rate as he done all what he could for you. I wish you all the best and better health.”

“I have always had a great experience with Dr. Horizon and his staff.  Yes, the office can be busy at times and when you call to ask a question or schedule an appointment there is often a wait, but I also know this is common in most medical practices.  In-person I never have found the office overcrowded or hectic at all.  Dr. Horizon generally spends quite a bit of time with me and is very thorough, patient, and compassionate.


I went to Dr. Horizon after years of auto-immune issues that no-one could diagnose, and my other rheumatologist was calling chronic fatigue and secondary dysautonomia.  Dr. Horizon immediately picked up on clues that I had been trying to point out to the previous doctor, and he took xrays which showed definite inflammatory damage.  He ran labs that supported his diagnosis and started me on a medication that has helped me a lot.  He also has treated my husband for familial psoriatic arthritis, with a medication he just took for a few months, and then stopped once the labs showed improvement.  No side-effects, and his symptoms are completely gone.  His siblings have deformed hands and are in a lot of pain, but my husband won't have to go through that now, thanks to Dr. Horizon.


I am an RN and Dr. Horizon has always taken the time to review his rationale with me and has only seemed rushed during one appointment, which was a quick follow-up.  Otherwise he has taken quite a bit of time with me (more than most any other doctors I have ever seen) and is so comprehensive and clear.  I am so grateful for his care and knowledge, insight and wisdom.  I also appreciate his back office staff who are always friendly and kind, and the front office even asked me the other day if I would like a bottle of water when I checked in for my appointment.  They have transitioned to all electronic signatures, which makes checking in a breeze.”

Dr. Karayev


"The most caring, thorough doctor in Los Angeles. I traveled from South Dakota to see Dr. Karayev, and he was worth the travel. Seeing any other doctor is a waste of time. Bless you Dr. Karayev."
