Richard Duane Semmler

Dr. Richard D. Semmler, 80, of Annandale, Virginia, passed away peacefully on January 13, 2026. Born on January 12, 1946, in Webster, New York, Richard lived a life marked by discipline, determination, and generous spirit.

From an early age, Richard distinguished himself as an exceptional athlete. A standout track star at his high school in Webster, he carried his talent and drive to the State University of New York at Plattsburgh. There, he became one of the program’s most celebrated distance runners, ultimately earning a place in the SUNY Plattsburgh Athletic Hall of Fame—an honor that reflected both his remarkable achievements on the track and the respect he earned from teammates and coaches.

Beyond athletics, Richard was known for his character, loyalty to friends and family, and his deep pride in the communities he called home. Whether reminiscing about his days on the track or offering encouragement to younger athletes, he remained a model of perseverance and humility throughout his life.

He was a member of the Mathematics faculty at Northern Virginia Community College (NOVA) where he taught for 45 years and earned many awards for his excellence in teaching. Upon his retirement, he was named Emeritus Faculty. One of his passions was his service to the community where he built more than 50 houses with Habitat For Humanity. He endowed several scholarships for students at SUNY Plattsburgh and NOVA. Richard's philanthropy was recognized on an episode of ABC's 20/20. Every Thursday he could be seen serving meals to the homeless at DC's Central Union Mission.

Richard’s legacy endures in the memories of all who knew him and in the example he set through his dedication, kindness, and quiet strength.

Special thanks to the staff at Arden Courts Annandale for their compassionate care of Richard during his convalescence.
