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.

My experience
All the medical staff were pleasant and make you feel really at home and comfortable.

The entire staff were very friendly, polite, respectful & professional.They made me feel very comfortable from the minute I walked in until the minute I left. And what I really liked the most was they called me the next day to see how I was feeling after my procedure. I would definitely recommend woodholme gastreology & the endo center for all GI related problems.

Thank you for your care!
I recently had a procedure with Dr. Onwueme at the Woodholme Gastroenterology Center. Dr. Onwueme and all the staff at the center were absolutely wonderful! I've already referred friends and expressed to them that I couldn't have had a better experience! In addition to saying thank you to Dr. Onwueme, I want to send a thank you to all the staff who cared for me. (Brittany, Margie, Krystal, and Renee) You all are the best!

Wonderful doctor and staff
Dr Onwueme and his staff are an unbelievable team. From the moment I arrived till the end of my visit I was cared for by a dedicated team of friendly, smiling people. Everyone from the office staff, to nursing, anesthesia and the techs, were really professional. And Dr Onwueme is one of a kind!

This is what excellence in medical care looks like
Dr. Onwueme is the most professional, empathic, and all-around excellent physician I have ever gone to. And at 68 years old, I’ve been to a lot of docs. I wish he could be my primary care provider.

EXCELLENT CUSTOMER CARE
Not only was Dr Onwueme very attentive to my situation, the whole staff was excellent also. The made a very UNPLEASANT procedure more tolerable. To add icing on the cake after speaking with the doctor about my family history he recommended that I get the procedure every 3 years instead of the recommended 5 showing his concern for my situation and I AGREE

The entire procedure went like clock work.
The entire team was like poetry in motion. Fast, efficient and very caring. I don't really care for medical procedures but the way I was treated; I don't want to see them again too soon, but they have made me feel good about the medical profession.

Not what I expected, In A Good Way!
I totally expected the worse....I was sure that this was going to be a very unpleasant experience....but I was wrong! My initial meeting with Doctor Onwueme eased some of my fears but the experience at the EndoCenter erased each and every trace of apprehension that I was feeling about the colonoscopy procedure that I had scheduled! I barley had a few moments of 'down' time to think about the procedure because the nurses where talking to me and told me...the hard part (the prep) was over....and it was! They explained everything that was happening and was going to happen and the next thing I knew....I was waking up and it was over! They called my friend who was there to pick me up and I was off to eat! Great experience....I'm glad the nurses were so friendly and basically held my hand through it all!

Excellent experience
My whole experience with Woodholme was excellent! The staff was welcoming and professional, explained everything and put me entirely at ease. This was my 3rd procedure and their team was top flight every time! And Doctor O was the same. He fully explained the procedure and the results each time. He is very person oriented and makes you comfortable. It’s an important diagnostic test, and the team does it so well.
