Dr Maher has been nothing but kind ans compassionate to me. Not only does he listen to my problems bit he also takes the time to get to know me as amd person and my family. Yes I may have to wait at times but that is because he is spending time caring for others!

Avoid at all costs. After an endoscopy and esophageal dilation that he did, I regurgitate after every meal, when I bend over, whenever I burp, cannot lie on my left side at night without burning pain, air escapes esophagus upon exertion. Avoid this man.

I have been coming to this doctor/ office 4 over TWENTY YEARS. It wasn't bad enough that my last colonoscopy, When I encountered trouble with the prep, leaving me with 2 much medicine NOT NEAR ENOUGH FLUIDS, I was severely dehydrated and Surely close to shock. The office and hospital knew ahead of time that I may encounter an emergency, & not ONE PERSON followed through. This week, I waited over an HOUR! ....With fractured rib & was NEVER SEEN. OFFICE RUNNING 90MIN. BEHIND!! Shameful!!!

Dr. Maher had rounds while I was in the hospital and I had been seeing Dr. Lynch (Loved him!) and he was very curt and lacked compassion and bedside manner in my opinion. Was in and out with a 'complete' evaluation in less than 3 mins. Did not really care to listen to anything I said and just walked out. When I mentioned it to the nurses, the response was 'ya, that sounds like Maher'. That's not ok in my opinion.

I had diarrhea for 4 months, going the bathroom 15 times a day. I'm 72 this was very dangerous for a person of my age. Dr. Maher could do nothing to stop the problem. I would go to him and he would recommend some over-the-counter product that I could have asked a pharmacist for and then charge $420.00 for the 15 min. visit while I could not even sit there as I would be in the bathroom. This man is completely incompetent. We went from him to Dr. Ruben and he fixed the problem in one visit.

I would absolutely recommend Dr. Maher, my experience was extremely positive. I felt at ease and in good hands when I was experiencing extreme pain. He explained what was happening and his thoughts on the matter well, referred me to a great surgeon, and actually listened to me. Bedside manner was stellar, he was respectful and kind, and I've had some very bad experiences with previous medical doctors. The rest of the staff was also very kind and professional. I'm shocked the score is 2.8/5!
