Dr Marino was very tentative to the problems. He is an awesome Dr.
Dr Marino LISTENED and was thorough in his approach.
Dr. Marino is so professional and insightful. In fact, Dr. Marino was recommended to me by my retiring gastroenterologist. Great Doctor!!!
Keith & Andre were great, they took great care, were prompt, pleasant & professional.
As soon as a signed in and completed my paperwork Dr Marino saw me. He explained what I needed to know in a professional manner
Dr. Marino is the best there is. Always on time for appointments. Super friendly and so is his stff
Great Dr and staff Dr. explained everything thoroughly. Staff was very pleasant. Would highly recommend. Overall great experience.
I was referred to Dr. Marino for a follow up colonoscopy. He reviewed test results from my emergency room visit. Thank God he caught something to do with my heart on those tests and referred me to a cardiologist. I'm scheduled for an angiogram and potential stent. This was completely missed at Ochsner's ER. Dr. Marino may have saved my life. Thank you! His office staff was very professional and accommodating. My colonoscopy and upper endoscopy was smooth sailing. The facilities are very nice. Highly highly recommend!!!
Dr Marino was both friendly, and professional, kind and informative. I saw him 3 yrs prior and he greeted me like it was yesterday. I was informed and comfortable
No waiting in the lobby, seen the Doctor immediately after paperwork was done. Doctor visit was brief and to the point.
Dr Marino and staff were excellent. From the receptionist to the scheduler and everyone in between were awesome
I think Dr is a great Dr,and he listen to me as I ask him a 100 questions about my medical conditions. He also has good bedside manners.
Super fast professional and extremely nice 100% would recommend to anyone!
Dr. Marino himself is great!
His office staff could use some professional development training. You get a call from someone and they leave a message using their middle name and when you call back the staff doesn’t know who you’re talking about! You get to the person who last entered the communication and it’s the person that called! Am I wrong here but use the name your coworkers address you with! She happened to be nice! Generally, they are not very friendly and sound bothered when you call them. Perhaps, just wish them a good day.
Again, the doctor is great and you’re there to see him.

I thought that Dr Marino was great!
He really listened to what I had to say and asked me if I had any questions or concerns and listened to my heart. Great Doctor!!
The staff at this office was very nice too! Loved how they decorated the office! I felt very comfortable with everyone at this office. All were very nice and polite.

Dr Marino and his entire staff are wonderful and those young ladies and his staff are so professional and so sweet can’t ask for any better service than what Dr Marino and his staff gives you
The staff is excellent and Dr. Marino listens and offers options. I was seen a few minutes early! Good experience all around.
Dr Marino & staff very professional!!
Dr. M. J.Marino is one of a few good doctors. My brother is disable, he's pretty much like a baby. When he get sick he cry out. He can't speak or tell us what's wrong. But Dr. Marino is always there to help in anyway that he can. No rushing you in and out. He's very patient and take time with us.

Hi, folks here we go again, my brother Ronald has been seeing Doctor Moreno forever and just yesterday I accidentally pulled his feeding tube out when I was moving his t shirt .
I called the office close to closing time and asked if he could take care of it for me. Of course he said bring him in. I didn't
have my handicap van and I'm in my late 60s. So when I arrived at Doctor Moreno's office I couldn't lift dead weigh out of my rented vehicle alone. The doctor came out and did the procedure from the car. I was so grateful to him and the staff. Thanks again.
