Dr. Kaw has been my primary physician for almost a decade since I moved to Fullerton. I switched…read moreto him after a bad experience with a St. Jude GP. What I like about Dr. Kaw is that it is easy to book an appointment with him and you don't have to wait for weeks on end like St. Jude. He quickly and accurately diagnoses any medical issues you may have and I appreciate his expedient, straightforward manner and friendly demeanor. His staff is also great as they are responsive on the phone and fill prescriptions quickly - sometimes while I'm still sitting in the office so that they're ready for pick up at CVS down the road after my appointments. He also went the extra mile in getting a prior authorization for meds approved from my insurance, who have been very challenging to deal with to say the least. If you're looking for a competent and reliable GP in North OC, give Dr. Kaw a call.

I've been a patient of Dr. Kaw's for a long time, and something I noticed over the course of…read moreseveral visits was that he'd be very impatient and trying to get out of the room as soon as possible, almost like he's in a hurry and doesn't have time to listen to all your concerns. On several occasions it felt like he spent 3 to 5 minutes, and I believe his max is 10 minutes. I never felt like he truly cared about me as a patient; it feels like a McDonald's drive-thru. One day, I verbally expressed to him that I felt like he spent very little time with patients, and he lost his patience and became super furious saying that he felt insulted. He immediately kicked me out of his office. He should go into high frequency trading.

A special thank you to Esmeralda, his medical assistant, who is incredibly organized and always on top of everything. She really makes a difference. I hope I don't need another surgery, but if I do, I will absolutely return to Dr. Ali. I'm very grateful for the excellent care I've received and continue to receive during my recovery.

One of the things that impressed me most is how respectful they are of their patients' time. Appointments are run with remarkable efficiency, and they've even seen me ahead of schedule on multiple occasions (something that feels almost unheard of at most doctor's offices). Despite being so efficient, I never felt rushed. Every visit has been organized, attentive, and personalized. It's clear that Dr. Pyo has built a team that genuinely cares about their patients and works seamlessly together to provide an outstanding experience. I highly recommend this practice to anyone looking for compassionate, knowledgeable, and efficient care.

I had been in the market for medical insurance through Covered CA but the cheapest one I could…read morefind, that also allowed me to go to the doctors I had been going to for years, was a bit expensive. I decided to look into other options and did a search for places I could pay out of pocket. When I lived in Mexico, I had been using the services at a local hospital, paying a monthly membership fee for their services so imagine my surprise when I found out that the exact same system existed here. That was when I found Dr. Marisse so I booked an appointment. I found her originally on Zocdoc and the nearest appointment was in a month and a half. Within a day of making the appointment, I was called by the office to Nurse Shawna who wanted to make sure that I knew that all appointments needed a preliminary chat with the Doc, after which I could book my appointment. thanked me for letting her know that the next available appointment was that far away. It turned out there was a mix-up and that she did have more immediate appointments available. There is plenty of parking, as it is in shared parking lot with other businesses. However, there are two buildings with the same building number but with different locale numbers. Upper Echelon is in the building nearest to the AAA and the Farmer Boys. At the appointment, everything was clearly explained and we went over a sort of plan of attack, with regards to my concerns and what I needed to do. I appreciated paying less per month for the membership, which includes as many appointments as you want. The lab work and the tests are at wholesale prices so even with the membership fee and registration, all of this was cheaper than the plan I was going to get with insurance. What I appreciated was the quickness of getting an appointment. I have always hated waiting a few weeks, as a new patient, before actually being seen but I was able to book this within a week of the appointment. It was a week because their availability interfered with my work hours. Otherwise, I would have been seen earlier. All in all, it is pretty convenient and a wallet-friendly option. After that first appointment and the lab results came in, Dr. Marisse wrote a VERY long email detailing every point of concern. Which I appreciated because I went for answers and I was getting them. If you need a straightforward person to tell you what you need to be doing and not someone who has to be on your ass every step of the way, this is the ideal option. I would say the ONLY con is that they do not have appointments during the weekends. And since I work during the week, I have to take time off to go to an appointment.

They were incredibly kind, attentive, and took the time to answer all of my questions without making me feel rushed. Their professionalism, compassion, and positive attitudes truly made a difference and turned what could have been a stressful visit into a great experience. It's rare to find a medical office where you feel genuinely cared for, and Shawna and Karla exceeded my expectations. I highly recommend Upper Echelon Medical Office to anyone looking for quality care and exceptional customer service. Thank you both for making my visit such a positive one! Dr. Marisse is truly one of the best doctors I've ever had. She explains everything clearly, never makes you feel rushed, and always makes you feel like your health and well-being are her top priority. Her professionalism and caring attitude give me complete confidence in the care I receive. I highly recommend Dr. Marisse to anyone looking for an exceptional physician.

Let me tell you the story of the physician that saved my life. On a balmy day towards the end of…read moreApril, I had symptoms that required the skills of a neurosurgeon. The first spinal surgeon declined to operate on me as the site of surgery was too close to my brain stem involving my spinal cord. He referred me to his friend and that is how I got into contact with the neurosurgeon that saved my life, Dr. Erick Westbroek. I'm not sure why there is one disgruntled review on his Yelp page but nonetheless, I would like to speak accolades about his professional treatment of me with courtesy and respect. When he first examined me, I had a pretty serious medical problem that requires immediate surgical intervention. I'm talking about the kind that can lead to an occlusion of a vertebral artery could potentially cause induce a stroke. However, he was very calm and collected when he reviewed my medical notes and charts, knowing full well my medical condition even before I stepped into his office. Though he outlined the risks of the surgery, he spoke with a sense of reassurance that only someone who is confident in their skills can. I had my surgery within 2 weeks of initial consult with him due to the manner of my emergent medical condition. The day of surgery, he looked very relaxed and full of energy, ready to do my surgery. I was able to speak with him for a brief moment sharing how people of almost the entire orange county are praying for me and for him before the surgery. He made his surgical mark with a marker and before I knew what was happening after I was wheeled into the operating room, I was anesthetized. After what felt of only a minute, though the surgery lasted 6 hours, I woke up in the intermediate care unit where I had full use of my limbs again. As a physician, he restored my health. It was incredulous to believe. An ailment that I was afflicted with for several months was now abated. I could walk again! Not only that, I woke up to a new Pope elected after my surgery, Pope Leo. Furthermore, 2 of the nurses that visited and cared for me was my classmate and student. If that is not an uncanny coincidence, I don't know what is. I knew it was one of those where God provided Divine Providence. What a fitting name as the hospital where my life was saved... was owned by Providence. Thank you Dr. Westbroek for your consummate service to your patients. I would consider you a renown neurosurgeon in this county of Orange as there are few people with your subset of technical skills to operate at a precise level, restoring the health of the human body to its original function.

I'm surprised there isn't more reviews about Dr. Hone on yelp already! Hopefully more people will…read morerealize there is one of the best doctors around our little town of Hacienda Heights. So here's the story: I usually don't take any medication and don't trust western medicine for multiple reasons. However, I was very sick and started developing a very sore throat and started getting red patches on my soft palette in my mouth. I was horrified, since it was out of nowhere, and I've never experienced such a thing in my life. Since I couldn't speak, my boyfriend checked out yelp, and saw the lonely 5 star review that the reviewer below left. We both liked the fact that a doctor *gasp* actually spends time with his patients! So to the doctors we went. Okay, so it was 70 bucks just to see Dr. Hone. First of all, I've been to an ENT and spent 120 dollars, and didn't even get a fraction of the care that I got from Dr. Hone. As soon as I met with him, I knew he was a genuinely kind soul. He was very attentive and asked questions, and was never condescending. He explained to me that the reason I had strep-throat like sores in my mouth was because my immune system was fighting the virus, therefore allowing the bacteria to generate... or something like that, haha. He made sense, basically. He also checked my heart and we talked about my heart murmur, when he didn't have to. When the receptionist told him he had a phone call, he asked her kindly to hold it, continued speaking to me, and noticed her urgency, and excused himself to get on the phone. He came right back, apologized, and continued where he had left off, instead of forgetting, like I'd assume some doctors would. Basically, I believe there's nothing to lose here, as I've decided he's the best doctor I've ever been with. I absolutely recommend you to him!
