I was forced to pay a $200 penalty because I didn't know that his office closed at noon on Friday. Who runs a business like that? Also, these hours were never printed on any of the paperwork that I was given.

I have had several colonoscopies and a few endoscopies with Dr Abousaif. I am always impressed by the thorough notes he takes (which usually accompany the procedure results that I get a copy of). I appreciate his practice of reviewing previous results with me before we move towards next steps. I never feel rushed during my appointments with him and I do feel that he listens to any concerns I raise. I feel confident that he is familiar with my situation and that he is following up appropriately. I trust my G.I. health to him and have referred a friend to him. I highly recommend Dr Abousaif.

I write this review with immense gratitude for dr. Patel. After being very sick for several months…read moremy symptoms became increasingly worse and debilitating. Not knowing where to turn or whom to trust, thankfully a dear friend referred me to Dr. Patel. During my first appointment, Dr. Patel listened carefully to my concerns and understood that I was not only in severe pain but also nervous about being in a doctor's office. She quickly put me at rest with her compassionate and positive bedside manner. After her very thorough examination, she scheduled multiple tests. These tests identified serious but treatable GI issues, a hormonal imbalance, and a large ulcer that I was completely unaware of. Within a short time after starting treatment I was a newer better version of myself. Now, months later, I continue to improve and truly appreciate Dr. Patel for her incredible ability and willingness to address my medical issues.

She understood how exhausted I was and showed me warm caring as well, which I appreciated! The endoscopy she suggested went very smoothly, with her by my side to answer my questions, beforehand and afterwards. Since my two visits, I've called her office with questions to her medical assistant, Precious, and I received answers from Dr. Patel within a day as well as a personal reply from her via email. Though she is listed here with a Tustin, CA office, she has a Mission Viejo office as well--it's very convenient for me!

So I went to this place for a consultation appointment at 2:30 pm yesterday. I was there on time,…read morethen I checked in and signed a bunch of paperwork that makes medical care so expensive here and exonerates everyone in the process in case I get screwed. Then, I sat down in the lobby patiently awaiting to get my name called. A little later, another gentleman came in and told the front desk that he had a 2:45 appointment, and he did pretty much the same things as I did. After another 5 minutes or so, his name got called and he went inside. I didn't give it much thought thinking he could be seeing a different doctor than mine. Then later, another old lady came in for her appointment, I didn't hear what she said about her appointment time, and she got called rather quickly, but I was still waiting. After half an hour of waiting, my patience was running out, so I went to the front desk and asked them why people who had come after me went in before me. Well, my complaint kinda worked, my name got called and I was put into a room to wait. While I was waiting, I heard a doctor speak to a patient in an adjacent room, and it was a female doctor. I happened to know that my doctor was a female too. So I patiently waited for a good 5-10 minutes, and when I had a pretty good idea that the doctor was done with the patient and was walking out, I opened my door and saw the gentleman with the 2:45 appointment accompanied by a female doctor, who was the very same doctor that would finish me with my consultation in a few minutes. At that point, I was beyond being upset, but I kept my cool. Before I left, I requested a meeting with their office manager who patronized me with some bogus reasons that the front desk young lady was new, it was her 2nd day at work, lack of training, blah, blah, blah. Come on, I had been waiting in the lobby for over half an hour, and she was obviously the more senior one than the other dude. What really troubles me is why they would arrange not to see me with an appointment at 2:30 for a 5-minute consultation, instead they chose to see a patient with an appointment at 2:45 1st for a half an hour visit. Could it be that they enjoyed keeping a foreigner-looking individual waiting as he didn't look he belonged in the 1st place? That I don't really know, I certainly hope not. But isn't it an interesting time in which we live. Full disclosure: I am a Chinese, the gentleman is either a hispanic or southern Asian, the lady is white.

Dr. Mortensen is one of the best alternative healthcare practitioners I have had the pleasure of…read moreworking with. He has helped me tremendously through debilitating gut and health issues. Before finding Premier IFM, I had visited several conventional doctors but was unable to get clear answers. Dr. Mortensen took the time to investigate further by ordering comprehensive bloodwork, gut testing, and mold testing, which revealed longstanding gut dysbiosis and elevated mycotoxins. With his guidance, I began addressing these underlying issues and experienced meaningful improvements in my overall health. I want to be clear that I had preexisting gallbladder problems before becoming his patient. I eventually discovered that my gallbladder was severely infected and required emergency removal. This was not caused by any of the therapies or supplements Dr. Mortensen recommended. In fact, I believe his care helped strengthen and support my body leading up to the emergency. The ER doctors were amazed by how healthy my bloodwork looked before the procedure, despite the severity of the infection. I am incredibly grateful for Dr. Mortensen's knowledge, thoroughness, and dedication. His recommendations played an important role in improving my health and helping my body handle a serious medical emergency. I highly recommend him to anyone searching for a practitioner who genuinely listens and works to uncover the root causes of their health concerns.
