Dr. McGuire has performed endoscopies and colonoscopies on all four of us. He, unfortunately,…read morediscovered colon cancer in my late husband and eldest son. He was instrumental in the treatment of my husband and referred my son to the City of Hope. His professionalism is excellent as are his skills. In addition, he genuinely cares about his patients. There is nothing impersonal about his care. I do not say lightly that I trust him with my life. No, he doesn't walk on water. Among all the physicians I've been exposed to he is what I would call the best. How many doctors take time out of their schedule to attend a Celebration of Life Service for a 32 year old patient who lost his battle with colon cancer?

I am very thankful to Dr. Mortensen and his staff at Premier IFM. I came to his office roughly two…read moreyears ago. I was in bad health. I had chronic fatigue, brain fog, muscle and joint pain, low stress tolerance, along with digestive problems. I also needed some direction on nutrition regarding my hypothyroidism. I was subclinical and not taking any meds at the moment. He ordered blood work to see what my numbers revealed. His treatment plan included supplementation, a nutrition plan, along with lifestyle changes, and would help me treat leaky gut. I am happy to report it took a while to move all the pieces together, but the body started following. Now I am doing great. My energy is back, no more muscle and joint pain, my digestive health issues have resolved. The staff at Premier IFM are friendly and professional. They are ready to help with any questions and made all the moving piece for integrative care feel seamless. One thing I do want to mention, this level of holistic care is not cheap. Depending on your medical insurance, there will be out of pocket spending you might need to plan for. The staff can help you determine these details. If you find yourself dealing with painful, debilitating symptoms, and your health is suffering, getting seen and treated might be one of the best things you can give yourself. For me, I went from surviving each day to now thriving. I've regained my stride in life. Last but not least, I want to thank my Lord Jesus Christ for lording over my health and activating the healing process. He designed my body to heal and repair when the correct inputs from our environment and food we eat. Dr. Mortensen has been instrumental at helping my health journey with his knowledge and training to educate me on how to treat the imbalance in my health. God you get the glory and thank you for putting Dr. Mortensen in my path to regain my health, God bless you and your staff!

Update: I see your response. You should let your rude, unprofessional and unorganized wife know…read morethis information instead of posting it here. You were not the issue, it was trying to deal with her that was the main concern. She would not answer or return calls, would not give me my results after I paid hundreds of dollars for them, would not let me speak to a "doctor" and had a terribly rude demeanor. I thought maybe it was just to me, so as someone who has had my own successful business for 2 decades and likes to give everyone second chances because we all have bad days, I decided to test my theory. I had my best friend call to make an appointment and then my husband and she was rude to both of them each on different days, as well. Unfortunately for your career, she is a big problem.

I recently went to see Dr. Yoo for a colonoscopy. I found him through my insurance company website…read moreand saw that he was located nearby in Rowland Heights. When I called to make my appointment, I found out that Dr. Yoo moved his practice to a new building in Diamond Bar as of March 2024. Dr. Yoo's new office is located in the newly renovated Diamond Bar Medical Plaza, which was previously a Chuck E. Cheese (if you all were in the area when that was around). Looks like they are still in construction, as a couple offices are still vacant with plastic on the glass windows. The staff I encountered all very friendly and nice. Dr. Yoo was professional and clearly explained the process and indicated what I needed to do to prep for my procedure. I came in on a Monday and the front staff was able to fit me into an appointment on Thursday due to a last minute cancellation. This kind of procedure is not fun, but the entire staff made me feel comfortable the entire time, and the nurse who attended to me was so nice, I felt like my mom was taking care of me. =) She made sure I had extra blankets because I was cold and came by a couple times to made sure my IV was ok. I got a call the day after to follow up and see how I was feeling and if I was experiencing any issues. I appreciate the check in even though I was feeling good! I highly recommend Dr. Yoo if you need an gastroenterologist.

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.

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!

They are a highly professional and compassionate group, and I highly recommend them. Thank you so much to Dr. Singh and his wonderful staff!
