Also be aware that he will charge you $200 if you reschedule an appointment less than 5 BUSINESS DAYS from the scheduled time. Finally, be aware that his office closes at NOON on Fridays. I called his office at 2:30 PM on a Friday, trying to reschedule an appointment that I had for the following Friday. 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 asked my primary care physician for a different referral, and managed to find an office that has normal office hours and doesn't levy ridiculous penalties.

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!

My blood pressure and cholesterol was up, my hormones were down, and I was having weird panic attacks that I've never had before. After trying a few things that made me feel better but not great, my test results came back as having leaky gut in March of 2025. He asked me to get on a strict protein diet and gave me a few supplements, after about 3 months I was feeling better but still had to maintain my diet and supplements and now at month 5 I'm feeling great again and all my tests are stable. When my primary physicians only prescribed me medication to mask the symptoms Dr. Mortenson dug deep to find out what was causing these issues. I am still on the journey of healing my gut and stabilizing my gut bacteria but I can honestly say I feel much better and almost back to normal. I will never regret making the decision to call Dr. Mortensons office and don't even know how I would function if I just gave in and took the meds my primary was giving me and thought that was all that could be done. This team is amazing and you should never just settle with your health!
