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.

Dr. Merker is an excellent, knowledgeable, and experienced doctor. He recently leveraged his decades of experience to recommend and perform a colonoscopy. Other doctors would not necessarily have done this, due to my relative youth. He found both a polyp and colon cancer, thankfully very early. This could have saved my life, because under normal circumstances I wouldn't even have had a colonoscopy for 9 more years. He is also an excellent primary care, and takes the time to call very frequently to help me through my care.

Very down to earth and understanding. Instead of preaching, he works with the patient to get best results. Doesn't overlook any concerns, he explains everything in detail. He also stays after hours if a patient needs additional help. Nicest and greatest Dr I have and will ever meet!

Have been using Dr. Merker for over 25 years. He is very thorough, has a pleasant manner follows up and exudes confidence. Had several colonoscopies and endoscopies over the years. Entire staff is very professional. Would highly recommend.
