I started seeing Dr. Craig Mortenson around November of 2024. I was having all kinds of weird…read moresymptoms and my body was all out of wack. 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!

Hepatitis C Dr…read moreChapman was my Gastroenterologist for over 30 years. He always listened to my concerns. He always went over my results from medical tests and explained the numbers. My Hepatitis C was stable and clear in June 2018. He is a great and compassionate Doctor and I will always appreciate him. The office staff are very nice and helpful.

Kavita Singh was awesome - I had no stomach cramps whatsoever from her doing my procedure - she listened to me and removed all of the excess air.

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. The parking lot is the same near Placentia Linda Hospital where I have been before it's a big parking lot too I had a little hard time finding the place cause I thought it was the wrong area for some reason but I was ok. It's a clean and very professional office but also very caring and kind thank you so much. Have a beautiful day, be kind to everyone Aloha

So you…read morecan imagine my surprise that Dr. Matthews isn't seeing patients and will only do phone calls. I've currently been on hold for 15minutes!! Oh and did I say they NEVER called to share test results done over a month ago. Let me save you time and energy, don't pick Dr. Matthews. Well at this point don't pick St.Judes

DO NOT SEE DR. SCOTT SAINBURG!!…read more Completely rude and judge-mental. I was admitted to the ER prior and the doctors wanted a GI to do tests and look at me. He refused to do any test. Refused to look at the medical records. Claimed the ER doctors know nothing and it would be useless to look at their findings. Then he did nothing but lecture me on life. The whole time looking me straight in eye with a smirk, like he was waiting to see my reaction. Like he enjoyed it. Not only was he rude and unprofessional, he kept asking questions about my personal life totally unrelated to the medical conditions. I have filed a complaint with the office manager, my insurance, as well as my primary physician. I'm hoping to stop anyone from seeing him until he gets treatment or changes his behavior. He did nothing to help nor did he even try.

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. The keyword is patience. If you want a good Doctor with lots of knowledge that really takes his time with you, this is the place. I am extremely glad that my dad was sent to Dr. Chapman for care, he is an amazing Doctor.
