Best. Doctor. Ever. He genuinely puts his patients ahead of profit. So kind, well informed, and he takes time to explain everything. He has real compassion for his patients, never stops learning about new medical advances, and is always professional.

Dr Horowitz is the best doctor I have ever had. His knowledge is priceless and he has helped me through so much and so many ailments. His wife Peggy is wonderful too, and they make such a great team. I really hope he doesn't retire anytime soon, because I would not know what to do without their care. Thank you both.

Dr. Horowitz is the ultimate consummate professional and a caring doctor!!! In my 52 years, I have never known anyone with the patience, quick wit, and depth of knowledge this doctor has. I was recently.

Of all the doctors I have seen in my life, Dr. Horowitz tops my list. He is absolutely charming, professional, personable, and thorough. He takes his time and is funny too. I love the personal.

I rarely write reviews, but Dr. Horowitz and his staff are SO worth it. I've gone through a few primary care physicians since moving to Los Angeles 15 years ago and was never fully happy until I found Dr. Horowitz. I can't even.
