Dr. Horowitz and his wife Peggy have taken care of my family and several of my close friends for…read morethe past 20+ years. His broad scope of expertise, humanity, tact, and sense of humor have made a lasting positive impact on my life. Like most of his other patients, I can say without hesitation that I consider him and Peggy to be a part of my extended family. I will never forget receiving an unprompted call from Dr. H late in the evening many years ago after they learned of a sudden health crisis that my parent suffered. Thankfully, my parent's crisis eventually resolved; but that brief check-in from Dr. H touched me deeply. I knew that I was not alone and that he genuinely cared. Unheard of in modern medicine, when you call their office after-hours and connect with the emergency line, the phone rings at Dr. H's house. They trust their patients not to abuse that access; but the small number of times that my family needed it, Peggy and Dr. H were on the other end of the line, providing useful information and reassurance, even at 4AM. My experience as a patient of Dr. H's played no small role in my own journey towards becoming a physician. I often find myself trying to recall one of his totally unique and pithy one-liner jokes when I need to break the ice with a new patient. Family practices like this one are virtually impossible to find these days. The world would be a much better place if everyone had a medical team like Dr. Horowitz and Peggy.

All I can say is WOW!! I've never had such amazing service when it comes to doctor visits. From…read morethe first moment of contacting the office, Peggy was soooo nice and sweet. With covid and how things are run differently now, communication is KEY! Peggy sent me all the health forms that needed to be completed in a timely manner via email. She was wonderful at responding to my emails, and she made things so easy! They went out of their way to see me in person in a really short notice as my visit required necessary clearance for my nursing program. They only have certain days for appointments but she made an exception for me as my work schedule conflicted with their in-person office visits. Peggy also sent me my labs on a Saturday as I requested if she could send it to me as soon as they receive it.. they are closed on Saturdays and she did that for me (I am so grateful!). I also want to say that I drove from Monterey Park to Dr. Horowitz's office on a Friday during the time that there is so much traffic (traffic alone in this area if you already know is hideous) but I would do it again! Thank you so much Peggy and Dr. Horowitz!!

He's very kind n has a good memory even sense of humor. He referred my mom to several other doctors that were great as well. He's very cautious. The receptionist is sweet she speaks several southeast language thai, vietnamese, cambodian and I think some Chinese. I think she still works there. His wife runs the front office in the back. Not the sweetest, stand offish she doesn't interact with patients. I'm sure the complaints about the receptionist are about her. Not the real receptionist. Anyways my mom saw his son when he started his career. He seems smart. Im not sure its been awhile. I do know from experience Dr Yen senior is fantastic. The office is old n run down. But after u see the doctor it doesn't matter. Thank you Dr. Yen. I hope you are still practicing for the low income ( no insurance ) people n wish you happiness. I already referred my cousin to you. Thank you for your service and helping so many that need help and thank you for not making $$$ be the primary purpose you see patients.

Her office runs like a finely oiled machine. She keeps appointment times. Her office staff call you back quickly and they care as much as Dr. Adelman does. Her staff is fabulous just like Dr. Adelman! Dr. Adelman bends over backwards to ensure her patients get the best possible care and in the most timely manner. If I was old enough to see her, I would. I asked, but she only takes geriatric patients and I'm not quite old enough yet. But she helped me find a great doctor in the same network. She cares deeply and she listens. I can't say enough great things about Dr. Adelman and her entire staff. They treat you like family.

Interesting choice of decor; Anyways they never follow up with results for physicals, and without an appointment you'll be sitting in the waiting room for HOURS

If I could give ZERO stars, I absolutely would! BELIEVE THE REVIEWS!…read more This office is completely unprofessional and disorganized. I first called months ago to schedule an appointment and was given such a hard time that I eventually gave up out of frustration. Later, my daughter tried calling on my behalf and experienced the exact same thing , she even warned me, saying "Mom, she has terrible reviews." Unfortunately, those reviews were 100% accurate. Recently, I was diagnosed with pneumonia and was advised to contact my primary doctor. When I called again, the first woman who answered didn't understand me and immediately transferred me. For the record, they don't even answer the phone professionally! The second woman picked up and said, "What do you need?" no greeting, nothing. I told her I needed an appointment, and she asked if I was a new patient. After I explained my pneumonia situation, she said, "Oh yes, okay," and then told me, "Call me tomorrow, maybe I can fit you in." Maybe? Are you serious? That level of dismissiveness, lack of compassion, and unprofessionalism is unbelievable. This office clearly doesn't care about patients or proper service. Absolutely unacceptable experience from start to finish! I will definitely be changing doctors!

I spent YEARS trying to find a doctor that would take time to problem solve with me. As a woman in my late 30's my body is changing and she has been wonderful.
