First and foremost, I extend my deepest condolences to the family, friends, and colleagues of Dr. Donald R Henderson.

I am still in shock after learning of the transition of my friend and brother, Donald R Henderson, MD, MPH. Yes, Donald and I were more like brothers for more than 30 years. We were born and raised in Jacksonville, Florida. Donald’s mother (Mrs. Bernice Henderson) was one of my high school teachers. Upon my arrival at Howard University I became aware of Dr. Henderson, an affable, erudite sophomore student who was as involved with the political scene on campus as a senior. After graduating from Howard University, I chose the University of Florida for medical school. Donald was a 2nd year medical student involved in student activities (welcoming committee for new students). At the University of Florida, Donald was recognized as one of the most talented students in his class. In addition, he and I became friends, and his family and my family developed heartwarming friendships (Mrs. Bernice Henderson was also a teacher of my 2 younger sisters). After graduating from the University of Florida, Donald traveled North to Beth Israel (Harvard), and I traveled to California (UCLA teaching program Hospital). After completing my internship and residency, I decided to accept a position in a GI fellowship at UCLA. To my amazement, upon my arrival, I discovered that Donald was a senior fellow in the fellowship program. Subsequently, Donald established a practice of gastroenterology in Inglewood, California. After completing my fellowship in gastroenterology, Donald offered me a partnership in his practice. Together we developed a premier gastroenterology practice for more than 20 years, that was recognized as being one of the best GI medical groups in California. Throughout this 25-year relationship, Dr. Henderson adhered to the beacons of success (affability, ability, and availability). His patients loved him for his compassionate care, and his colleagues and referring physicians admired him for his erudition, endoscopic skills, and fund of knowledge. And, he was always immediately available to all of us (family, friends, patients, and referring physicians). I will truly miss my friend and brother in life.
