David E. Rivadeneira, MD, MBA, FACS, FASCRS, is director of Northwell Health Cancer Institute at Huntington and physician-in-chief of clinical strategic initiatives for Northwell facilities across eastern Long Island. He's a board-certified, multilingual general surgeon and colorectal surgeon who provides leading-edge care for colon and rectal cancer, inflammatory bowel disease such as ulcerative colitis and Crohn's disease, as well as diverticulitis. "I've always wanted to help people," says Dr. Rivadeneira, who completed his residency in general surgery at Weill Medical College of Cornell University, training at both New York-Presbyterian/Weill Cornell Medical Center and Memorial Sloan Kettering Cancer Center. Dr. Rivadeneira, who joined Northwell in 2013, works alongside a multidisciplinary team including oncologists, geneticists and nutritionists to give patients complete and convenient care. Consultations can usually be made within 24 to 48 hours at various Long Island locations-and everyone receives the care they deserve. "I treat people like I'd want a family member to be treated," says Dr. Rivadeneira. "I speak to patients in a way that helps them really understand their care-it's clear, concise and always compassionate." A professor of surgery at the Donald and Barbara Zucker School of Medicine at Hofstra/Northwell, Dr. Rivadeneira also instructs surgeons throughout the country and abroad. He is a fellow of the American College of Surgeons, the American Society of Colon and Rectal Surgeons and the Society of Surgical Oncology, among others. He also works closely with Northwell research partner Cold Spring Harbor Laboratory on tissue analysis for critical research studies for the very best patient care-now and in the future. "Seeing patients have better quality of life with no more pain, and seeing them enjoy major life milestones because of treatment-it just doesn't get any better than that," he says.

A Positive Experience from a Frightening Diagnosis

After a frightening diagnosis of Colon Cancer, I was blessed by being referred to Dr. David Rivadeneira and his awesome team. What can I say? I am a 79 year old woman, not knowing what to expect, and the minute I met Dr. D, I knew all would be well. Everything was explained in detail, and a doctor who was patient and kind, as were all his wonderful team and front office staff. From my family and I, I thank you from the bottom of my heart.

Dr. Rivadeneira

Dr. R walked me through the worst medical experience of my life. He was kind, caring and listened to my concerns. I called him a few times with emergency situation and was called back within minutes.

Outstanding Doctor

I can't say enough about my positive experience with Dr. R, the Northwell Health Network and my surgeries and stay at Huntington Hospital.
I mysteriously (I didn't rip during child birth, do not have gastric disease such as Crohn's) developed a rectovaginal fistula at the rarest possible spot at sphincter muscle. Doctor's near me, upstate NY, wouldn't even touch me. Dr. R first inserted seton drain to strengthen tissue and then performed fix months later. I am success story. I got my life back!

I want to thank you for saving me. I was experiencing extreme intestinal problems. For several years

In the past months the pain became unbearable to the point I didn't want to eat to avoid additional pain.
My PCP recommended me to your office. Your review and explanation of my conditions was detailed and explained in a way I could understand and relate to. You explained what I surgical procedure I would require and that I would not require a bag. I am now 2months later with no eating restrictions, no bag , I go to the bathroom without pain or pressure. and most of all able to eat and Thxs

My experience

My experience with Doctor Rivadeneira and his medical staff was exceptional
I went to him about a blockage in my colon after completing two colonoscopy’s . He spent the time explaining to me my condition. He even provided me with a drawing showing exactly what his proposal was to correct my situation. His ability to explain and lead in layman’s terms was outstanding. He has a great bedside manner. The doctor and his staff supported me throughout my surgeries. Thank you Dr Rivadeneira

His mission is saving lives

I first met Dr. Rivadeneira when I was diagnosed with colorectal cancer. It was a very frightening time for me. But, from our first meeting he calmed my fears with his kind and understanding manner. He listened and answered all my questions. I was not his patient. I was his family. He is a learned doctor/surgeon. His impressive C.V. is an understatement. I believe Dr. Rivadeneira's mission is saving lives. He saved both my life and my quality of life.
