Phenomenal surgeon. Saved my life

Dr. Marks saved my life. He convinced me to get a colonoscopy and colon cancer was found. Patients always come first with Dr. Marks. The wait is sometimes long if he has an emergency. But i don't mind waiting. He is a brilliant doctor and very skilled.

Dr. Marks has excellent surgical skills and I am so grateful for all that he has done for me. He is kind, to the point and does not over promise but totally overdelivers. When I was diagnosed with colon rectal cancer with the tumor being in a very difficult location, my son who is a medical rep and has watched Dr. Marks operate, supported that I make an appointment to see him. My son expressed his admiration for the time and skills that Dr. Marks takes with a patient to make sure that the operation is a success.While in the hospital and after the operation, Dr. Marks and his team followed up on my progress and showed genuine care and concern for my recovery. I have complete trust and very grateful to this gifted surgeon.

Pain is not an issue show details Pain is not an issue
by Lori Andrews on Jan 25th, 2010

I had a reconstructive surgery to my sphynctor by Dr. John Marks in 2007. The possibility of chronic pain was never mentioned. A second surgery was done by Dr. John Marks in 2008. The pain was not eleveated at all. I never got a call back after the second surgery and my follow-up appointment was cancelled and never rescheduled. I continue to be in severe pain in my private area on a daily basis. I am extremely frustrated by this and feel something should be done so that it never happens again!

Dr. John Marks is an excellent physician who I would trust with my life! I am a registered nurse and he has cared for me during the past 5 years. I have required hospitalization twice during that time for partial bowel obstructions and he patiently treated me with fluids and antibiotics and never pushed to operate (unlike many surgeons!). I recovered fully and am so grateful that he is my doctor.
