Dr. Keith Martin is a fantastic doctor!…read more He had done my previous two procedures, so I knew I'd be treated really well. He was kind, patient, very knowledgeable about not only my medical issue, but gave me the information to deal with what is a scary medical situation necessitating two procedures on the same day at the same time. He's very personable and professional, PLUS I got the notification of his initial assessment in my email really quickly.

After Dr. Martin ordered blood work, I had the tests done but never received a call with my…read moreresults. I've left two messages over a three-week period with no response. The lack of communication is unacceptable.

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.

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.

Melissa was my nurse she was so sweet and caring too, they heard everything that I needed to say and listened and told me what I need done. I really appreciate the caring and kind vibe that I got here and for sending me for testing right away so we can figure my issues. I will write more and update more after more testing. But thank you so very much from the bottom of my heart for caring and trying to help me! It means so much to have caring and kind doctors.

Dr. Sajen Mathews is the BEST Gastroenterologist I have ever met!! You need a doctor like him:…read morepersonable, thorough, knowledgeable, and of course, highly experienced!!!! He has diagnosed and treated many of my family members, too. Dr. Mathews is in such high demand and it seriously took me 2.5 months to secure an appointment with him!!! Worth the wait and I am beyond grateful for his expertise!! He might be able to see you sooner if it's a serious life threatening issue, but best to call his office and inquire.

I've called several times for an appointment but the first time they said they'd have to get back…read moreto me and call me back. They never did... Sorry I called back the next week and it took me a long time to get a hold of somebody and when I did they just asked me some questions and then told me they would call me back, I'm not holding my breath this time.......

I'm old.... so a colonoscopy is just part of life now…read more I called to make an appointment. The uninterested person on the phone looked over the schedule and said that Dr. Martin was available first. So I took it. I waited FOREVER in the lobby to get in to see him. Once I was in, he was very sweet. Asked lots of questions and took 2 pages of (handwritten) notes. I was in the office for almost 2 hours. I was the last one to leave. A day or so later, they called me with a colonoscopy date, and to look over the prep paperwork. I was given no paperwork. They didn't send me home with anything. So I had to go back and pick them up. When I went in to pick them up they were all eating and didn't even look up from shoveling their food. I had to reach out... annoyed, they found someone to take me back and get the papers. She was very friendly and sweet, super apologetic. Colonoscopy went well, thank you.... So, I would say that as much as Dr. Martin was and the friendly person who gave me my paperwork is concerned, I would continue to use this office..... however, that front office staff is some of the most disinterested and unfriendly around. 5 Stars for Dr. Martin 1 Star for the staff

He does take his time with each patient and so you must be patience when waiting for your appointment. The office staff is wonderful, but always busy. Donna, Dr. Chapman's nurse is amazing as well.
