Anne Mattern, a consulting school physician who worked for the Montgomery County health department for three decades, died Nov. 15 at her home in Rockville. She was 91.

The cause was colon cancer, said her daughter Carola J. Nesbitt.

Dr. Mattern specialized in child and adolescent mental and physical health. She guided teachers and administrators in matters including developmental and educational screening, special placement of students, evaluations for physical and sexual abuse, and the care and education of mentally and physically handicapped children. She retired in 1989.

Elizabeth Anne Dentry was born in Baltimore, where she received a bachelor’s degree from the College of Notre Dame in 1943. She graduated from the University of Maryland’s medical school in 1947 and ran a general surgery private practice in Aspen Hill, Md., in the early years of her career.

She was a past chairman of Montgomery County’s retired physicians committee, volunteered at local influenza vaccination clinics and received recognitions for her fundraising and organizing efforts with her medical school’s alumni group, her daughter said.

Dr. Mattern participated in tennis tournaments in Maryland and on the East Coast and won a seniors doubles championship when she was in her early 70s, her daughter said. Dr. Mattern also participated in the Maryland Senior Olympics and coached softball, basketball and tennis in Rockville.

Her husband of 48 years, Dr. Carl F.T. Mattern, died in 1996. Survivors include six children, Charles R. Mattern of Rockville, Lucy A. Ertter of Laurel, Md., Susan E. Riegner of Fairfax City, Theodore D. Mattern of Woodbine, Md., Dr. Carola J. Nesbitt of Grayslake, Ill., and James G. Mattern of Gainesville, Va.; 11 grandchildren; and four great-grandchildren.
