Dr. Weiss is congenial and down to earth. He also has a great sense of humor. He listens! When I saw him for a consultation I had no sense of being rushed. He even looked over previous blood tests I hadbrought in. Quite a pleasant man! This is a good thing if he is going to be looking up your butt! The procedure was painless. Dr. Weiss spent time with me explaining what would be done and he answered all of my questions even though I had a lot of them. I had difficulty securing a ride home from the procedure as there was a huge snowstorm and everything was shutting down and my ride cancelled. Dr. Weiss waited three hours for me to finally find a ride! He had no other patients to attend to and he could have gone home, He did not seem annoyed at all about waiting. He just told me he couldn’t wait much longer and he would need to leave soon, and then I finally found a ride home. I will definitely go back to Dr. Weiss for all my gastrointestinal needs. He has a family history of colon cancer, as do I, so he understands. He trained with the best in the city. I felt secure and comfortable in his hands. Afterwards he sent a report to my doctor and he also printed out the report for me! He is kind, witty, and he knows what he is doing. I want to repeat that he really listened to me. That is a quality that is getting rare these days! Dr. Weiss is my new gastroenterologist and I am very happy about it!

Doctor Weiss is very a nice and humorous professional. I showed up to my appointment late and he waited for me even though I was his last patient that day. The interview was not rushed, he made sure to ask aboutall my symptoms and discomforts. The atmosphere was very friendly and he made me feel at ease. It is such a relief to finally find a good doctor.

Dr. Weiss was awesome. I showed up an hour early hoping he would take me and he accommodated me quickly, spent time with me discussing my symptoms and was knowledgeable. He was also very understanding about my decision to avoid medicationif possible and presented me with options, and respectfully left it up to me. He feels like family, kind and gentle and humorous, but you also know you're in good hands of a medical professional. I left the appointment looking forward to my colonoscopy next week!

He seemed uninterested in my concerns. Only suggest that i drink more water rather than try to find out more information about my symptoms and why i might be having them. The wait time was about 15 mins and the actualvisit was no more than 10 mins long. I got more help and suggestions from a co worker currently taking a nutrition class.

I liked Dr. Weiss a lot. He took me in right away, was welcoming, patient, and even appropriately humorous. What I liked the best though that he did not rush me, carefully heard out my complaints and walked me through thenext steps/procedures. What I loved the most was that he personally called me to let me know one of the time slots we had discussed for a procedure had been filled, and later when I picked a slot and confirmed by calling his voicemail, he again took care to call and email me to confirm that we're on.

Personable attitude with focus on patient, Robert Weiss carefully listened about my health history and promptly suggested best course of action in compassionate consideration of my general concerns. I am disabled under the act and I havebeen involved with almost every hospital/doctor in NYC, so, while I am a new patient of his, my experience with Doc Weiss and his office was highly satisfactory in every sense.

Although a friendly doctor, my evaluation was cursory at best leading to an incorrect diagnosis, wrong treatment prescribed, and needless pain. I only found out after seeing a second opinion.

I really liked the doctor but he was very resistant to testing for an illness that I was trying to exclude, even when I hv the classic symptoms. My primary care wanted me tested for it. It is okay if iteventually gets excluded but The dr did not listen to me and was eager to exclude it out of hand due to it being somewhat rare. I really need to get it excluded and got a second opinion and the doctor prescribed the test for it. I liked Dr Weiss a lot. He's really cool, but I really needed him to have an open mind so I can get a correct diagnosis.
