David Mark Posner

David Mark Posner passed away on January 18 at age 80.

Born on June 27, 1945, David grew up in Brooklyn, NY. He was a dynamic and dedicated person who cared greatly for his family, excelled as a physician, and pursued diverse interests in his lifetime.

David attended Midwood High School and embraced the opportunities of growing up in New York: riding his bike across town, taking up photography with the city as his canvas, soaking in jazz at local halls, and making trips to Coney Island for a Nathan’s hot dog. He enrolled at Bard College after high school and graduated from Hofstra University, where he studied biology and spent his summers working as a clinical lab technician. He attended medical school at Kansas City University.

He was a loving father, grandfather, and husband. Nothing was more important to him than spending time with his wife of 55 years Suzanne; children Nicole, Eric (Amanda) and Andrea Kate (Joshua); six grandchildren—Alexandra, Roman, Miles, Asher, Perry and Max; and brother Paul and his wife Barbara. He was predeceased by his loving parents Anne and Herbert Posner. David adored his family, taught them so much, and encouraged them to live life to the fullest. Proud of his Jewish heritage, he was a longtime member of Temple Isaiah since the 1970s.

One of David’s greatest strengths was his knowledge of many subjects. He could discuss almost any topic. He was a fine physician who not only treated patients but loved getting to know them as people. He was caring and compassionate. After medical school, David joined the United States Public Health Service, taking his internship in Staten Island. He became board-certified in family practice and opened offices in Baltimore, Howard County, and Frederick. Later, he shifted to emergency medicine, practicing for 25 years at hospitals all over the country, including in remote communities where the need for quality physician care was in high demand. He found emergency medicine exciting and fulfilling. His passion for patient care stuck with him throughout his life and he continued practicing at urgent cares and local medical facilities.

David was a lifelong learner and encouraged his children to always be open to expanding their horizons. Education was very important for his children and himself. He earned his MBA from Loyola University in the 1990s. In recognition of his value to public service, he was appointed a member of the Adult Public Guardianship Review Board in Baltimore.

David loved the arts and to travel. He regularly attended performances at the Washington Opera and Metropolitan Opera and enjoyed trips to Europe, Australia, Israel and the Far East with loved ones. A musician himself, David was a talented drummer. He played in the school band and as a hobby growing up. He had an eye for treasures and accumulated a collection of beautiful art and wine throughout his life.

His adventurous spirit led him to get a pilot’s license in medical school. He owned a Cessna for many years and liked going on golfing trips with his friends, taking his kids to camp, or just hopping down to Ocean City for a hamburger. He even blended his passion for travel and medicine, serving as the passenger physician for the Holland American Cruise Line.

Staying well informed on world happenings was always important to David. From a young age, he read The New York Times, The Washington Post, The Wall Street Journal, and the Financial Times daily, and was always surrounded by books and magazines. He felt for the injustices of the world and believed in helping others regardless of their circumstance. Warm and approachable, he lit up social gatherings with easy conversation. Spending a day soaking up the sun or an evening out with friends over good food and wine was a joy for him.

At his core, David was incredibly generous. He was always giving and ready to help his family or a friend in need. He was one of a kind, loved life and taking in the beauty of the world. He will be dearly missed.
