Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Excellent doctor.

Excellent doctor; thoughtful; thorough
Telehealth
I have a history of a rare disease that puts me at very high risk for a number of gastroenterology-related conditions and diseases. Dr. Grunkemeier was not only aware of my rare disease, but he knew how to approach long-term monitoring and testing. In addition, he has a holistic lens and approach. Lifestyle changes are now an important part of my long-term view and approach. I am not waiting around for these diseases to emerge, rather we are actively on the offensive. Dont ask me how, but this patient has a plank-game now. 90 seconds and holding! Further, and most importantly, I spend I a lot of time in doctors offices and it gets to be exhausting. Dr. Grunkemeier is always someone I am happy to see and talk with. He makes me feel he has the time for me and he answers my all my questions.

Excellent! Clear communication and compassion
Met Dr. G when he was treating my mother in law. It was refreshing how he handled her situation with candor and compassion. Since then, I sought Dr. G out when I had GI issues, and he's been great.

I have referred several people to Dr. Grunkemeier.
He has been treating me since 2007 with regular upper endoscopies and colonoscopies, and I have the utmost confidence in his knowledge and level of care. All of my visits have been positive experiences - not only with Dr. Grunkemeier, but with the entire staff. They have both exceptional customer service and clinical expertise.

Outstanding doctor
This was my first visit with Dr. Grunkmeier. He listened very carefully to every word that I said and did not make any notes when talking to me. When I looked at my post-visit notes, I was amazed that he had captured every minute detail.

My PCP was able to work me into Dr. Grunkemeier's schedule with a four day's notice after becoming alarmed over a CT scan. I was seen by Dr. Grunkemeier inside forty-five minutes after arriving in his office and he explained what was needed going forward. The procedures were scheduled and completed. This all happened over three weeks.

Informative the whole way through
I’ve had three procedures from Dr. Grunkemeier at the Oregon clinic. Each time, I felt well informed going into and after the procedure. I was able to see and discuss results as needed. I was informed of follow up care and future visits. Dr. Grunkemeier was personable with a sense of task at hand and revealed a sense of humor in speaking with him afterwards. I would highly recommend the Oregon clinic and Dr. Grunkemeier.

I left GI clinic due to the wait times and feeling very rushed for an appointment. At times Dr Grunkmeier would spend time a lot of time going over options and such, while others you would spend less then 10 mins after waiting over an hour.
