The front office made the entire process incredibly seamless, and I was able to secure an appointment within just one week.

Although they were quite busy on the day of my procedure, resulting in a slightly longer visit, the efficiency, care, and dedication of the entire team were outstanding. They are a highly professional and compassionate group, and I highly recommend them. Thank you so much to Dr. Singh and his wonderful staff!

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.

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.

I was referred to Dr. Hwang by my surgeon, Dr. Rad. From my…read moreinitial call to schedule an appointment and speaking with Cammy, I felt "at ease." It's always hard going to see a specialist as you may not be sure they understand your concerns and feeling comfortable with the Physician. My initial appointment was supposed to be a "TeleHealth" one due to COVID - 19. I wasn't really keen on it due to my issues but Dr. Hwang was highly recommend by Dr. Rad and I trust him implicitly and agreed to the "TeleHealth" visit. Again, from my initial contact, I was thoroughly impressed. Calls were returned almost immediately as were emails. Two days before my "TeleHealth" visit, I received a phone call saying Dr. Hwang could see her patients in person and was asked if I wanted to go in, I immediately said "YES!" When I checked in I was greeted by the most friendly, Cammy! I didn't have to wait long to be brought back to the exam room. The nurse (I don't recall her name ), took my vitals and although I could not see her entire face due to having wear a mask, I could tell she was smiling as I could hear it in her voice and see it in her eyes. Before I knew it, Dr. Hwang came in along with her Nurse Practitioner, Richard. Dr. Hwang made me feel at ease right away. She was already knowledgeable about my health history - and it's a long one. (Many times I feel health records aren't always read). I was impressed on how much she knew about me and felt like I was already an established patient! Dr. Hwang explained everything to me simply and really took the time to get to know me as a person! She had prescribed a medication for me and there had been a problem with my Pharmacy as they said they did not receive the new prescription. I called Dr. Hwang's office back and literally within a half hour, Richard, the Nurse Practitioner, resolved the problem and my prescription was actually ready! Richard even called back to let me know he had remedied the problem - note, he called after hours to boot. Even he was surprised to know that I had already picked up my prescription! Dr. Hwang's office was that quick making sure was "taken care of," prior to the long weekend! Vanessa was essential in scheduling a procedure for me. I wasn't even home and she was already calling to offer days and times for me to choose from. I was immediately emailed the information that I would need! I know this is a long review, but there are several people - people who offer their care to make it so! Everyone I was in contact with was friendly, professional, and offered genuine care! I'm rest assured that I can trust my health care needs with Dr. Hwang and her staff. I'm confident they will all make a great team in getting me to feeling better. Thank You To All.

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!

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.
