    Great Experience Here…read more My mother has been going here for some time the service is great here, my husband & I were looking for a dermatologist, and we found this office. I recognized it right away because of my mothers visits, when the nurse was speaking to me I mentioned my mom, and they remembered her. Dr. Brent Martin attended to our specific needs, and I have to say he was the most pleasant Dr. to speak with very sweet, he was happy to serve us, he knew exactly what we needed and gave us quality service. I was very pleased with my visit I will definitely be retuning again for any dermatology needs. Dr Martin You Give Quality Service Your A Very Sweet & Friendly Dr. The Conversation Was Enjoyable. We Appreciate Your Service & Care You Give Thank You Very Much To You & All The Staff.

    Absolutely one of the friendliest, most caring medical offices you'll ever experience. The staff…read morethere, led by PA Andrea, genuinely care about each patient. I learned more about myself medically here than with my own PCP. Andrea made sure to check everything on me and provided valuable health related information I would not have gotten elsewhere. Because of that, I can honestly say she saved my life by catching a soft cell sarcoma on my leg early. We had it removed immediately and now I'm worry free. Everyone there, including Dr Nguyen, speaks to you eye to eye and wants to help. I Highly recommend.

    Dr. Lin has decades of experience having seen thousands of patients. He is open to answering all…read moreyour questions and gives you ample time for consultation. It is best to be prepare yourself before going in as with any doctor. Medical history, symptoms, concerns, questions about research you've done on your own, etc. I end up feeling peace of mind just listening to him reiterate things I already studied to confirm or discard my suspicions. He is very understanding and open-minded but is the type to stear away from diet restrictions to focus on immunotherapy. Appointments last about an hour so if you're going to the Orange office, prepare to pay $1.00 for the parking structure since you might be 5 minutes over or try to find parking on the side for free. Irvine office has free parking lot. Be punctual for immunotherapy shots and expect to sit or stand in the office for 30 minutes after. Irvine office lets some people wait out the shots in empty office rooms when the waiting area is full.

    Dr. Lin has been an absolute God send in my life. I have struggled with allergies my entire life,…read morerelying on over the counter allergy medication only to barely survive allergy season every year. I was plagued with constant runny noses, sore throats as a result of unrelenting post nasal drip, eye infections from watery eyes, and the inability to breathe through my nose from a very early age and for whatever reason, it wasn't until I headed off to college that I decided to take action and find an allergist. I was referred to Dr. Lin from a family friend and went in to have a consultation. Lin is a very sweet guy and has very helpful staff. He was able to answer all of the questions that I had, test and provide results as to what I was allergic to, and get me started on treatment within the span of like two weeks. I started getting shots in June following my senior year of high school and by October or so of my Freshman year of college I noticed significant results. I no longer suffer from almost any of the symptoms that I have dealt with my entire life (except the occasional watery eyes in the spring). I would also like to say that while I was up at school for my freshman year and was unable to go into his office in Orange, his staff was able to ship my medication to a completely different allergist in Los Angeles so that my commute to get treated would be easier and more manageable. Maybe I am a special case where the treatment worked like magic, I really have no idea, but coming to Dr. Lin has been literally life changing and will remain one of the best decisions I have ever made in my life.

    I can't say enough good things about this office. Dr. Hariri is not only extremely knowledgeable,…read morebut also genuinely kind and thorough. He takes his time with each patient, answers every question, and makes sure you fully understand your treatment. You never feel rushed, which is so rare these days. Berlin is an absolute gem so sweet, patient, and caring. She brings such a warm energy and makes every visit feel comfortable and easy. It's clear she truly cares about the patients and goes out of her way to make you feel welcome.

    I'm not sure where all these 5 star reviews are coming from but maybe we just got the bad end of…read morethings. We scheduled an appointment with hopes of finding and answer. Since this doctor had great reviews we were hopeful for our appointment. Fast forward to the day of our appointment which we waited for weeks by the way to get one. We went to his Glendale office location and we were there 15 minutes earlier. I mean it's only polite to be there a few minutes early to any appointment right? Their nurses called us in and we were assigned to one of the rooms to wait for the doctor. The nurse then proceeds to ask a few questions regarding health history. All is good here. Then a few minutes pass by, no check ins to let us know where the doctor is. Eventually an hour passes by and I came out to look for the nurse to ask her what's the doctors ETA. She then says oh I texted him already and he is on the way here. He should be here in 15 minutes. So we decided to wait for an additional 15 minutes. At this point we have already waited a total of 1 hour and 15 minutes mind you. Still, no doctor. I come out again to ask her will he be attending today? Because we really waited for this appointment to come and was looking forward to it and he is nowhere to be found and we are now starting to get frustrated with the lack of respect for our time. She then proceeds to say "I understand, he does this all the time I'm sorry. I've already followed up with him again and he said it will take him another 30 minutes to get here because he had to attend to another patient." Uhm.... Excuse me??? At this point I was really upset and decided to just reschedule. To add salt to the injury, this nurse said. We can reschedule you but we won't have anything until a few weeks from now because he's going on vacation. Wow. We are lost for words. This doctor does not respect your time or cares for his patients. I should have read the other reviews he has on Yelp. For some reason he has 3 different accounts on here. I suggest you read reviews from all 3 accounts. But digging further, other patients also have complained about the same exact thing. How can you trust to be in a care of a doctor that lacks respect for your time and does not value his patients? God forbid you have an urgent follow up, you can't even follow up with him because I doubt you can even get a hold of him based on our experience. He can't even be bothered to be there on time. Almost 2 hours late is beyond me. I have never heard of a medical professional do anything even close to this and I've had my fair share of having different doctors for my care. I can't even tell you his bedside manners, we didn't even get a chance to meet him! But I can probably guess, it isn't as good as people say on his reviews. Anyways. If you value your time and you want a doctor on your team to respect your time as well. Do yourself a favor and find another doctor. There are plenty out here that have amazing bedside manners. We decided to go with another allergist, everything went through smoothly. From appointment to our doctor having the best bedside manners. So no. I will never recommend this doctor. It's so disrespectful to have anyone waiting for 2 hours.
