Dr. Joseph M. DiMisa, 52, a dentist in Washington since opening his first office here in 1958, died Tuesday at Suburban Hospital after a stroke.

A native of Washington, he was a graduate of Gonzaga High School and Georgetown University. After serving with the U.S. Air Force from 1950 to 1954, he earned a degree from Georgetown University Dental School.

In addition to maintaining his dental practice, Dr. DiMisa was on the faculty of the Georgetown University Dental School. He was active in D.C. and Southern Maryland Dental Societies.

Dr. DiMisa was a eucharistic minister and member of the parish council of St. Bartholomew's Catholic Church in Bethesda, where he resided. He was a charter member of the board of Casa Italiana at Holy Rosary Catholic Parish in Washington. He belonged to the Villa Rosa Home Guild and the Gonzaga College High School Fathers' Club.

He is survived by his wife, the former Margaret Jackson, and four sons. Joseph M. Jr., thomas C. and Stephen J. and John F., all of Bethesda; a daughter, Anne Van Soyoc, of Laurel; his parents, Francis and Elvida DiMisa of Washington; two sisters, Elizabeth Altman and Dolores Stowell, both of Silver Spring, and a brother, Francis Jr., of Olney.

The family suggests that expressions of sympathy be in the form of contributions to the Gonzaga College High School Building Fund, or to the Casa Italiana Building Fund at Holy Rosary Parish.
