    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.

    I always have excellent experiences at Upper Echelon Medical Office in Fullerton. From the moment I…read morewalked in, everyone was welcoming, professional, and made me feel comfortable. A special thank you to Shawna and Karla--they went above and beyond to provide outstanding care. 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.
