Johannes Karl Martensson

He is a great doctor and Kelsey is the best PA ever.

Sorry to read horror reviews. I found Doc to be quite friendly, yet professional. He got me on a better path after 6yrs and 5 specialists. The PA, Kelsey is extremely knowledgeable

I can’t even call this man a doctor. I went to him due to duct issues in my intestines. After extensive tests being done, he never diagnosed problems with my gallbladder which I had excessive sludge. I was told I needed surgery to put a stint in. I was in so much pain after surgery I was admitted back in the hospital for emergency surgery to remove the stint. I would recommend never to go to this doctor. I can’t even call this man a doctor. I went to him due to duct issues in my intestines.

Absolutely horrible physician. I wouldn’t give any stars. He was in the hospital stumbling around like he was drunk. He yelled at a patient’s family and he was talking in riddles contradicting himself.I don’t recommend. I don’t like speaking negatively but if it helps anyone, I felt I had too.

Perfect experience. Start to finish. Top notch

Doctor and staff were amazing t,diagnosed my problem and through surgery was able to help me solve my issue. I would highly recommend the services of Dr Martinson Thank you

What a moron. All he was concerned about was wearing a mask. As a medical professiol he should be well aware that a cloth mask provides ZERO protection against viruses. A sheep is even worse than a quack

I have been a patient of Dr. Martensson for over 25 years. He has ALWAYS been there for me through many operations and now dealing with stomach cancer. My daughter called to notify his staff that I was having issues with internal bleeding, he told her to IMMEDIATELY bring me to his office, when we arrived I was seen and Dr Martensson contacted the ER and had me admitted from his office. He is an incredible, very caring man and pays attention to every detail involved in my wellbeing. I highly recommend him and THANK HIM for everything he has done to keep me going at the age of 90. There are few doctors still around that really care about their patients. He's one of the BEST! BTW - his staff is very helpful in making sure the doctor gets all of his messages and that I always get the medicines & appointments I need to work with my family transporting me to follow up appointments. I've been BLESSED to be in his care for so long!

He is an idi@t and a devout mask devotee not a science based practitioner. He would rather see a patient die than treat them without a mask. His staff and he himself do not wear two masks as recommended by the CDC. They also do not wear N95 masks which are the only effective masks. The policy of the good doctor is to wear a face covering, as he himself stated, "For the common good" and that could be something as simple as a bandana. Take your sheep mentality elsewhere as it is not needed here. A doctor is supposed to be based in science, not hysteria or fear of litigation

Went to his office orignally to have an internal Hemorrhoid banded. The nurse talked me into a Colonoscopy also. Never seen the doctor til day of surgery, no personality at all. He said about 5 words to me. Then to start the procedure they started to do the colonoscopy before I was completly out. Then to top it off the Hemorrhoid never fell off, which again was my main purpose. Then they called me to tell me to come back to get the results of the biopsy, I asked if it was negative and they said yes, but still wanted to come back just to tell me it was negative and charge me another office call.

Went in for Celiac diagnosis, and DR almost did the wrong procedure. I realized his mistake just before anesthesia. On the follow up appointment ( waited for one hour and fifteen minutes) the nurse practitioner needed my help reading the pathology. I asked to speak with the office manager and they informed me they don't have one. I don't like leaving negative feedback, but choosing a DR can determine your future health so I feel obligated to share. Went in for Celiac diagnosis, and DR almost did the wrong procedure.

Great doctor ,very knowledgeable and helpful.

I have been a patient of Dr. Martenssons for 15 years. He is a great doctor. He listens to your concerns and addresses your issues. I have total faith in him. His office staff has always been pleasant. I would and have highly recommended him. I will be at a loss if he ever decides to retire.

I had an EGD procedure yesterday and the medical staff was outstanding. I have never felt more safe and relaxed before such a procedure. The nurses and the doctors were extremely efficient and professional. I would definitely recommend this doctor and his medical staff.

Do not go to this Dr! He is totally incompetent. Doesn't listen when you're trying to tell him your symptoms, always interrupting & belittles you if you question him. So disorganized so be prepared to wait a long time in waiting room...Sometimes even having to reschedule patients in waiting room. Didn't take my issues seriously. Pretty much said it's all in my head so go see a Physiatrist.

I had 4 appointments at his office but never saw him. Is he a real person? Also I received a bill from Medicare for a procedure that was never done . His staff is inefficient and confused. Overall a bad experience I would not recommend him to anyone .

If it was not for Dr. Martensson, I would not be alive today. This man has gone above and beyond to keep my as healthy as to be expected considering my condition. I am proud to say that I am a patient to Dr. M . I have had two other gastro doctors and not one of them could give me a straight forward answer. Dr.M gave it to me straight, and helped me get to where i am today!

I tried to make an appointment with this Doctor for my wife who was very ill. I was told abruptly by the woman answering the phone that my wife who needed an emergency appointment could not be seen until March of 2016. I called on Feb. 2nd of 2016. Most importantly I was told she also needed a referral from our primary care Doctor, which is NOT true. We have United AARP which does not require us to have a referral for any specialist, per a phone call to United AARP on 2-2-16. I would not go here
