About me

Preetha Ali, MD, FACS, FASCRS is a general and colorectal surgeon at MedStar Washington Hospital Center. Dr. Ali is double board certified in general and colon and rectal surgery. She specializes in the diagnosis and treatment of a wide variety of benign and malignant diseases in the colon and rectum, including common complaints such as hemorrhoids, anal fissures or fistulas to more complex conditions such as colorectal cancer and pelvic floor dysfunction. Dr. Ali especially takes great joy in improving the quality of life in women with pelvic floor disorders.

Dr. Ali performs a variety of surgical and endoscopic interventions including open, laparoscopic and robotic abdominal surgery (DaVinci Xi) for colon and rectal surgery; simple and complex anorectal surgery; and colonoscopies for screening and diagnostic purposes. She is also certified in placement of sacral neurostimulator devices. In all cases, Dr. Ali strives to provide her patients with the most effective and least invasive treatment method possible while also following national standards and guidelines.

Dr. Ali has a special interest in minimally invasive colon and rectal surgery via laparoscopic and robotic approaches of colorectal cancer and diverticulitis. She finds robotic surgery an exciting tool as it allows doctors to access areas that can be difficult to reach while also offering great visualization. To that end, she is certified in robotic surgery.

Dr. Ali obtained her BA in Chemistry from University of Pennsylvania, where she graduated magna cum laude. She went on to receive her medical degree from the University of Maryland School of Medicine. Dr. Ali trained in general surgery at Stamford Hospital in Stamford, CT. Next, she completed a fellowship in colon and rectal surgery at Swedish Medical Center in Seattle, WA.

Philosophy of care

“My practice is rooted in empathy, empowerment, and advocacy. When patients come to me, they often say that they felt like no one was listening to them or taking their symptoms seriously. I want my patients to know that I am going to listen and collaborate with them to address all their symptoms. It is my goal to make my patients feel comfortable and safe to share with me all their concerns, so that we can reach the best health outcomes possible. With all my patients, I am willing to go the extra mile: whether helping a patient feel comfortable through an awkward hemorrhoid exam or walking through all their options so they can make the best health decisions for themselves. When I work with referring physicians, I see our relationship as a partnership. I will always circle back with them to provide our mutual patients the best and most comprehensive care.”
