Dr. Farrell, originally from Clarksburg, W. Va., was a 1955 graduate of Campion Jesuit High School, a Jesuit boarding school for boys in Prairie du Chien, Wis. He was a 1959 graduate of the University of Notre Dame.
Dr. Farrell completed his medical training in 1965 after his internship at Medical College of Virginia in Richmond, and residency at Children’s Hospital of Pittsburgh.
After completing his medical training Dr. Farrell served in the U.S. Navy Medical Corps at the U. S. Naval Hospital, Pediatrics, Camp Lejeune, N.C. In 1968-69, he served in Vietnam pacification program as a Navy pediatric physician advisor II corps, Milphap Team N-4 in Nha Trang and Saigon treating plaque, malaria and tuberculosis.
After being discharged in 1969, he continued to serve in the U. S. Navy Reserves receiving an honorable discharge as Lieutenant Commander April 1975. He received the National Defense Service Medal, Vietnam Service Medal and Vietnam Campaign Medal.
After his military service, Dr. Farrell moved to Reston in 1971, establishing Farrell Pediatrics in Hunters Woods Village Center.
In 1985, he moved his practice to Sunset Hills Professional Center. The practice still bears his name and has provided care to thousands of young patients in Northern Virginia.
“Dr. Farrell was such a good clinician that in 1989, when my daughter was diagnosed with leukemia, he knew the diagnosis before the blood test came back,” said Reston resident John Farrell, a lawyer who often joked with the doctor because the two shared the same name.
Dr. Farrell was preceded in death by his father, Dr. Marcus E. Farrell and his mother, Mae Ann (Hurray) Farrell. His first wife, Carol (Aston) Farrell, died in November 2015 in Raleigh, NC.
He is survived by his wife Nancy; brother Marcus E. Farrell Jr. (wife Ellen); son John David Farrell Jr. (wife Kerry and grandchildren Victor, Patrick and David); Laura Farrell Page (husband Jeff and grandchildren, Carter, Natalie and Logan); Michael Farrell and Julene Farrell; and stepdaughter Cynthia Connell (husband Paul and grandchildren Brian and Kevin).
