A Fairfax County center for senior citizens is receiving a federal grant that will make it more accessible for the handicapped as well as the elderly.

The center, in the Sleepy Hollow United Methodist Church, 3330 Holloman Rd., west of Seven Corners, will receive a $24,500 grant under the Older Americans Act.

A symbolic presentation of the approved grant was made last week by Carolyn Carter, of the Fairfax County Area Agency on Aging. The actual check will be presented next month, she said.

The grant will be used to bring the center, which opened last April, into physical compliance with regulations of the Department of Health, Education and Welfare and the Fairfax County code, said center director Kitty Arone. The additions will include ramps for wheelchairs and walkers, toilet facilities for the handicapped, improvements to the heating plant, a sprinkler system and smoke detectors.

Arone said the center's original one-year, rent-free lease has been extended to three years by the church.

The symbolic presentation was made at a luncheon attended by about 80 people, including Peggy Fisher, wife of 10th Congressional District Rep. Joseph Fisher, and Fairfax County Supervisor James Scott.

Also in the audience was Dr. Dennis Jackson, whose 100th birthday was celebrated at the center last month. Jackson, a retired professor of pharmacology, now lives in Annandale with his son and daughter-in-law, Charles and Marie Jackson.

The Rev. Charles Swadley, the church pastor and a key figure in the center's creation, said arts-and-craft activities have boomed at the center, as evidenced last week by scores of exhibits in wood carving, jewelry making, painting, crocheting and weaving. Visits by elderly citizens are running 30 to 60 per week. The center is open Tuesdays and Wednesdays from 10 a.m. to 3 p.m.

Professional counseling on Thursdays, by appointment, is being added this month.A monthly newsletter is also printed.

"Our goal for 1979 is at least 40 persons per day," said Swadley. Regular activity, he added, is likely to be expanded from two days per week to three, plus two days of seminars, workshops and trips. A course in CPR - cardio-pulmonary resuscitation - is to be added late this year or in 1979 if demand warrants. The course would be taught by the American Red Cross.

The center is nonsectarian and non-profit. Its phone number is 534-6461.
