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 Marks is an excellent doctor but I can’t say that for his staff. Waited 6 months to get an appointment for a colonoscopy and then forgot to tell me to stop a medication. I cancelled and don’t want to go through it again.

I feel that Dr Marks went over my concerns and had a plan to take care of them. I will follow up in two weeks.

Post a ResponseAre you Dr. Marks?
My son (college age) had severe gastrointestinal problems. Since we have cancer that runs in our family (colon, appendiceal and kidney/bladder cancer) we requested a CT or MRI, to be followed up by other tests. The pain had been pretty significant, thus elevating our concerns; yet we waited for numerous days with the doctor's staff saying we "have the reports in hand" but he had not reviewed them yet. We finally went to another GI to get an opinion and got fast results and great communication. They scheduled immediate follow-up procedures to review some problem areas. Dr. Marks may be a very decent doctor, but with the lack of response on something we obviously had significant concerns about, we were not comfortable with his lack of communication.

D. Fisher in Katy, TX – May 29, 2018
Post a ResponseAre you Dr. Marks?
Dr. Marks was a phantom Doctor. Upon my initial visit I was led to the exam room and then seen by a medical practitioner. Dr Marks never took the time to step in and introduce himself. I did see him vaguely when I had my gastroscopy as I was falling deeply into unconsciousness due to anesthesia.
I returned to the office several times thereafter and again was seen only by his medical practitioner.
I have never received medical treatment by a physician at such impersonal level.

From the receptionist to the medical assistant and Dr. Marks, my husband and I were thoroughly impressed. Dr. Marks is thorough, serious about his care, yet personable and able to engage on a personal level. He listens, explains and is pro-active in looking to resolve individual health issues related to his area of expertise.
