Upper Marlboro, MD |
I recently had a procedure done by Dr. Mahjoob and I've barely seen results. After the procedure, I waited in the waiting room for him to follow-up with me to see how I as doing and it took a couple folks to go get him to come speak with me. Once he came by the waiting the room, he looked at him like what I was still doing there. Needless to say, the service as not what I expected.

Terrible bedside manner. Performs procedures on patients but waits days to check on them if he checks on them at. If you ask for him to come back because you as his patient has questions he'll come to your room with an attitude asking "what do you want now". I was in horrible pain after he performed an ERCP on me and he showed no concern whatsoever. Will not ever let this doctor near me again. If you want a patient doctor who cares about your well being Mr. Mahjoob is NOT the one.
A patient with above name was not treated or performed ERCP in 2016 or in the past by Dr. Mahjoob. it appears this person has fear of revealing his/her true identity due to psosible her/ his underlying mental conditions. He or/ she also misidentify the title of Doctors, which is another sign of their mental disturbance. While we strive to provide the best care possible to all patients, however here and there we would confront by troubled individuals.
