If HACC invited everyone who ever studied at the community college to its upcoming series of birthday parties, its guest list would have about 673,000 names on it.

HACC celebrates its 50th anniversary this year and will kick off a year-long celebration of its heritage with local birthday parties at each campus in the next week.

HACC's York campus has only been a part of the college for 11 years, but its quick growth and flexibility in scheduling have made it an asset to the York community, said Jean Treuthart, the campus' vice president.

The York campus started in 2003 as a small extension of the main college in Harrisburg. Only about 250 students were enrolled in the first classes in York, which were held in high school classrooms around the area, Treuthart said.

By 2005 the school moved to its current location at 2010 Pennsylvania Avenue. And two years later, it had acquired official campus status from the state Department of Education, which means it offers the same services that Harrisburg's main campus does.

Now, the campus has about 3,000 students enrolled in a number of programs, including nursing, business administration, criminal justice and psychology, Treuthart said.

"Any of our projections (for growth) for York were just beat," he added.

HACC's president John "Ski" Sygielski will visit the York campus for the birthday party Tuesday. The event is not open to the public, but is a precursor to the upcoming events throughout the year that will involve the community.

The next event, to be held in April, is a week-long celebration when the public is invited to "Rediscover HACC." Visitors can sit in on classes, see displays and demonstrations, and perhaps witness Sygielski on his 150-mile bike trek to each of the HACC campuses.

Treuthart, who has been at the York campus since its first year, said it has been exciting to see the campus grow and become a part of HACC's service to the diverse students in the area.

Treuthart said HACC as a whole has grown 20 percent since 2008, a sign of continued growth as an entire community.
