Built by someone who understands
the decisions that matter
Dr. Henry Conter is a board-certified medical oncologist who trained at MD Anderson Cancer Center, led global pharmaceutical strategy at Hoffman-La Roche, and served on Canada's national drug review committees. He built Kesis & Sisters because he saw firsthand how the gap between cutting-edge evidence and daily clinical decisions was widening — and knew technology could close it.
