About Sajen J. Mathews
My father was a factory worker and had great ambitions for me. He spent almost half of his salary on my education. The day I was accepted into the India Institute of Technology, the world’s finest engineering school, was one of the happiest of his life. Imagine his disappointment when I quit after a year to go to medical school. It was very difficult to tell my father, but I knew I had a passion for medicine and making a difference in people’s lives.
The collaboration between St. Jude Medical Center and St. Jude Heritage Medical Group allows me to focus on medical advancements, and practicing at the state-of-the-art Knott Family Endoscopy Center ensures my patients have access to the newest technology and treatment options available today.
Offering the latest procedures with the newest techology is a vital component of my practice, but I believe it is equally important to treat patients the way I would want to be treated. I take the time to listen to my patients’ concerns, educate them about their options and work with them to improve their health and well-being. This is why I became a doctor.
