Darren Kastin, M.D.

“I chose a career in medicine for the simple reason that I wanted to make a difference in people’s lives. When it came time to choose a specialty, I found gastroenterology attractive because it embodied, for me, a combination of what medicine is all about. As a physician, my objective is to heal the sick wherever and whenever possible, improving the quality of life for people with very real problems. In digestive medicine, achieving this objective requires a broad knowledge base and diagnostic skill while combining direct therapeutic intervention as well as medical management.”

“I believe that being a physician and a specialist means making a daily commitment to doing what’s best and most appropriate for each individual I see. From experience, I know that patients just want to get better, and that’s why I’m here. It’s why I never limit or restrict my availability and always give them the time and attention they need. Ultimately, excellent medical care is all about caring, and I never forget that. It’s what motivates me to do my best for every patient.”
