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.

Dr. Marino is 10/10. He got me on same day for an issue I was having AND got me in to see a specialist I needed VERY quickly. Wouldn’t have happened without him. Best bedside manner too. You’re in good hands.
I had a positive experience seeing Dr. Mark Marino at MGA last week. He was pleasant and his plan reasonable . The staff members were polite and friendly . They were very busy so you do need to be patient with them and their process .
Highly recomended, Dr. Marino!

Great Doctor, Great Staff, enjoyable place to go. I enjoy my visits and would recommend them to anyone. Looking for to my next appointment. Thanks for everything.
I have been a patient of Dr. Marion’s for years now. I appreciate the time he spends during appointments and after procedures to discuss my health, results, treatment plan etc. Dr. Marino returns phone calls promptly & has always been available to answer any questions or concerns I have. The office staff are super friendly too. I live on northshore now but still make the drive to see him. Highly recommend!
