Crohn's disease expert Berkeley Limketkai, MD, had wanted to become an aerospace engineer. He loved science, but something was missing. Medicine became more than a glimmer and Dr. Limketkai trained as an internal medicine doctor before specializing in gastrointestinal disorders, and Crohn's disease, more specifically. Dr. Limketkai is now an advocate for his patients, working with them to find treatment combinations that can give them back a more normal life, despite a chronic illness with major effects on digestion.
