Testimonials

What our patients are saying

"I had the pleasure of working with Dr. Sugumaran in multiple capacities at Barnes Jewish Hospital. He is one of the most well rounded surgeons I have worked with. He has exceptional skills when it comes to general surgery, emergency surgery, trauma, bariatric, and ECMO. His technical skills were impeccable and he was very knowledgeable in the cardiac ICU. I would gladly let him take care of myself or my family."

Benjamin B

"Dr. Sugumaran is amazing with his patients and very respectful to the nurses. I remember seeing him advocate for a patient in the ED who was being neglected. He got the patient transferred to ICU which is the level of care that was needed. The patient’s family was so thankful and couldn’t stop voicing their gratitude to every nurse on the unit. Working alongside him as a nurse, we always had an open line of communication and he lifts the atmosphere of the workplace."

Kaylin J

"I currently work as a Nurse Practitioner at Dana Farber. I was introduced to Dr. Sugumaran 2 years ago, and since then he has been a consistent and reliable source for seeking an expert opinion. He is both knowledgeable and considerate in his advice, and he is very thoughtful in his approach to patient care. I would highly recommend working with him!"
